▼ Evanescent Wave Assist Features (EWAFs) are features that are sensitive to near-field radiation that modify diffracted order intensities from photomask patterns. In implementations studied in this thesis, the EWAFs increase a transmitting feature's image contrast and Normalized Image Log Slope (NILS). In this way, the EWAFs are a way to improve image fidelity for high-resolution features. The assist features consist of local, buried grooves located around transmitting mask regions. These grooves reside in otherwise unused areas, since they are located under or on top of opaque mask absorber regions. In these "buried" locations, they are not optically visible to the lithographic system in a traditional sense. Designs are explored for both top-surface and bottom-surface EWAFs on 1-D and 2-D layouts. Using EWAFs, 27% image contrast improvements have been shown on contact layouts, as well as best-case image contrast improvements of over 2X on 1-D slot-type mask layouts. Dependence of EWAF effect on mask absorber material and bottom-surface relief shape is studied, as well as polarization sensitivity and the role of Surface Plasmon Polaritons (SPP). TM polarized light creates a normal-component field enhancement that amplifies surface waves across suitably conductive absorbers. These waves can then interact with bottom-surface EWAF grooves, and convert to propagating based on grating action. The converted orders may then interact with standard transmitted orders from a transmission feature, resulting in enhancement or suppression, depending on EWAF tone, pitch regime, and illumination angle. A demonstration EWAF sample, as well as a reference sample with no grooves, was fabricated at the RIT SMFL and tested using a Variable Angle Spectroscopic Ellipsometer (VASE). Accounting for pitch deviations during fabrication, as well as lateral inter-layer alignment offsets gives diffracted order responses that agree with SPP resonances observed in the samples at normal incidence and diffracted order enhancement factors that agree with simulation.

▼ We present an examination of near-wall colloidal
particle dynamics, their associated measurement techniques and
applications to micro- and nano-scale fluid flows. The dynamics of
small particles in solution exhibit interesting and useful
properties. The most popular measurement methods for characterizing
their motion are imaging techniques based on
evanescent wave
illumination, namely total internal reflection fluorescence (TIRF)
microscopy, which allows the imaging of small, fluorescent
particles (10 nanometer to 10 micron) within a few hundred
nanometers of a fluid-solid interface. In some instances, the
particle intensity may be used to determine particle's distance
from the wall, and thus, the three-dimensional particle motion. In
the presence of a solid boundary, the random, Brownian motion and
the convective motion of the particles is modified due to
interactions between the particle and wall. Some examples of these
effects are hindered diffusion, shear-induced rolling,
electrostatic repulsion and van der Waals attractive forces. This
has immense consequences for fluid velocity measurement techniques
that infer fluid motion from the measured particle motion.
Evanescent wave illumination was applied to measure single particle
dynamics and also to infer the fluid motion in several fluid
systems. The dynamics of semiconductor nanocrystals or quantum dots
(QDs) and single molecules were examined and applied as tracer
particles, extending the resolution of particle velocimetry probes
down to about 10 nm. Additionally, the inherent intensity variation
of QDs with temperature was used to measure the local fluid
temperature within the
evanescent field. QDs were also applied to
measure high speed micro-flows (near 1 cm/s) within about 200 nm of
the fluid-solid interface. A three-dimensional TIRF velocimetry
(3D-TIRV) technique was developed to measure slip velocities at
microchannel walls with tracer particles on the order of 100 nm.
The three-dimensional adhesion dynamics of large (6 micron
diameter) particles were examined to determine the kinetics of
adhesion ligands and receptors for applications to leukocyte
dynamics. Finally, the techniques of fluorescence microscopy and
in-line holographic imaging were applied to characterized the
structure and dynamics of electrospray droplets.

▼ The need for label-free integrated optical biosensors has dramatically increased in recent years. Integrated optical biosensors have many advantages, including low-cost, and portability. They can be applied to many fields, including clinical diagnostics, food safety, environmental monitoring, and biosecurity applications. One of the most important applications is point-of-care diagnosis, which means the disease could be tested at or near the site of patient care rather than in a laboratory. We are exploring the issues of design, modeling and measurement of a novel chip-scale local
evanescent array coupled (LEAC) biosensor, which is an ideal platform for point-of-care diagnosis. Until now, three generations of LEAC samples have been designed, fabricated and tested. The 1st generation of LEAC sensor without a buried detector array was characterized using a commercial near field scanning optical microscope (NSOM). The sample was polished and was end-fire light coupled using single mode fiber. The field shift mechanism in this proof-to-concept configuration without buried detector arrays has been validated with inorganic adlayers [1], photoresist [2] and different concentrations of CRP proteins [3]. Mode beating phenomena was predicted by the beam propagation method (BPM) and was observed in the NSOM measurement. A 2nd generation LEAC sensor with a buried detector array was fabricated using 0.35μm CMOS process at the Avogo Technologies Inc., Fort Collins, Colorado. Characterizations with both single layer patternings, including photoresist as well as BSA [4] and immunoassay complexes [5] were done with cooperative efforts from various research groups. The BPM method was used to study the LEAC sensor, and the simulation results demonstrated the sensitivity of the LEAC sensor is 16%/nm, which was proved to match well with the experimental data [6]. Different antigen/antibodies, including mouse IgG and Hspx (a tuberculosis reactive antigen), have been used to test the immunoassay ability of LEAC sensor [7]. Many useful data have been collected by using the 2nd generation LEAC chip. However, during the characterization of the Avago chips, some design problems were revealed, including incompatibility with microfluidic integration, restricted detection region, strong sidewall scattering and uncoupled light interference from the single mode fiber. To address these problems, the 3rd generation LEAC sensor chip with buried detector arrays was designed to allow real-time monitoring and compatibility with microfluidic channel integration. 3rd generation samples have been fabricated in the CSU cleanroom and the mesa detector structure has been replaced with the thin insulator detector structure to solve the problems encountered during the characterizations. PDMS microfluidic channels and a multichannel measurement system consisting of a probe card, a multiplexing/amplification circuit and a LabVIEW program have been implemented into the LEAC system. In recent years, outbreaks of fast spreading viral diseases, such as…

▼ Esta dissertação versa sobre a parcela evanescente que constrói uma série convergente e, desse modo, impossibilita sua permanência em uma forma última. O estudo da evanescência como a possibilidade de movimentar um corpo afirma a potência do infinito de uma vida finita e a impossibilidade da permanência a partir do movimento incessante do infinitamente pequeno. Afirmar a irredutibilidade do movimento a um ponto de chegada e a possibilidade da criação de um outro si ou de um si sempre provisório é considerado, neste estudo, um modo de inventar a vida. Com Foucault e Deleuze, apresenta-se um corpo como uma estrutura atravessada por linhas que operam e compõem instantaneidades, como forma em constante mutação. Trata-se de produzir ecos entre os domínios da filosofia e da matemática, na afirmação da diferença como aquilo que constitui um corpo. A impossibilidade da permanência é tomada como transgressão de limites impostos, ao considerar uma formação como a produção de infinitas formas.
This dissertation is about the evanescent parcel that builds a convergent series and, this way, precludes its permanence in an ultimate form. The study of evanescence as a possibility of moving an object affirms the potency of the infinite of a finite life and the impossibility of permanence from an incessant movement of the infinitely small. Affirming the irreducibility of movement to an arrival point and the possibility to create another form or an form always temporary is considered, in this study, a way to invent life. Departing from Foucault and Deleuze, an object is presented as a structure crossed by lines that operate and compose instantaneities, as a shape in constant mutation. It is about producing echoes between philosophy and mathematics, considering difference as what constitutes an object. The impossibility of the permanence is taken as a transgression of imposed limits, when it consideres a formation as a production of infiniteness forms.

▼ During the past two decades the dramatic developments in cooling and trapping of gaseous atomic samples has produced a variety of techniques to manipulate the external and internal atomic states with electromagnetic fields. The research efforts so far have mainly focused on studying the fundamental aspects of modern quantum physics, although numerous practical applications, e.g., in integrated matter-wave optics and quantum information processing, are expected to soon be added to the already established atom-optics products, such as atomic clocks and acceleration sensors. One of the most promising foundations for the practical applications of Bose-Einstein condensates (BECs) and coherent matter waves is the technology based on the creation of microscopic atom traps on the surface of a solid substrate. This trapping technique has recently been used to successfully control the motion of microscopic atomic samples and to significantly simplify the creation of BEC. The main research topic of this thesis is the development and design of surface-mounted atom traps on transparent dielectric substrates. Such traps could provide an extra flexibility and stability for the experiments, since they would allow unimpeded control of atoms with laser light and provide reduction of magnetic-field fluctuations associated with the thermal motion of free electrons in the substrate material. The thesis describes several novel approaches to the creation of such surface traps by superimposing repulsive
evanescent optical waves with strongly localized magnetic or electric fields. These fields can be produced by either conductive or permanently magnetized, optically transparent patterns imprinted in a thin layer on a transparent dielectric substrate. The
evanescent wave can also be used to cool the atoms in a gravitational field before loading them into the microtrap. The lateral confinement of the atoms on the
evanescent wave can be realized with a thin-walled hollow laser beam, the creation of which is demonstrated in the thesis. The thesis also describes certain general aspects concerning
evanescent-wave cooling. In particular, the influence that multiple reabsorption of resonance-frequency photons in a cloud of
evanescent-wave cooled atoms has on the cooling efficiency is investigated. Also, a theoretical model based on classical statistical mechanics and thermodynamics is introduced to show how a microtrap on an
evanescent-wave mirror can be used to decrease the temperature, increase the phase-space density, and provide temperature conserving spin-polarization of the atoms.

▼ Current assumptions for the limits of immersion optical lithography include NA values at 1.35, largely based on the lack of high-index materials. In this research we have been working with ultra-high NA
evanescent wave lithography (EWL) where the NA of the projection system is allowed to exceed the corresponding acceptance angle of one or more materials of the system. This approach is made possible by frustrating the total internal reflection (TIR)
evanescent field into propagation. With photoresist as the frustrating media, the allowable gap for adequate exposure latitude is in the sub-100 nm range. Through static imaging, we have demonstrated the ability to resolve 26 nm half-pitch features at 193 nm and 1.85 NA using existing materials. Such imaging could lead to the attainment of 13 nm half-pitch through double patterning. In addition, a scanning EWL imaging system was designed, prototyped with a two-stage gap control imaging head including a DC noise canceling carrying air-bearing, and a AC noise canceling piezoelectric transducer with real-time closed-loop feedback from gap detection. Various design aspects of the system including gap detection, feedback actuation, prism design and fabrication, software integration, and scanning scheme have been carefully considered to ensure sub-100 nm scanning. Experiments performed showed successful gap gauging at sub-100 nm scanning height. Scanning EWL results using a two-beam interference imaging approach achieved pattern resolution comparable to static EWL imaging results. With this scanning EWL approach and the imaging head developed, optical lithography becomes extendable to sub-22 nm generations.

▼ Evanescent waves are created by the wavemaking process during tank testing.
They have long been a nuisance for engineers as they contaminate the wave
field in the tank and result in additional inertial force experienced by a wavemaker.
Evanescent waves are created by the mismatch between the motion of the
wavemaker and the motion of the
uid particles in a progressive wave. To avoid
contamination of test results, often a considerable distance must be left between
the wavemaker and the test area. This space requirement may be costly for small
research groups or companies who wish to have a facility to perform some basic
proof-of-concept tests in-house, but are restricted for space. The initial aim of
this project was to develop a wavemaker which minimised this space requirement
over a large range of frequencies. The exploration into the behaviour of evanescent
waves from the point of view of the fundamentals of hydrodynamics has been
very enlightening. It became clear with the discovery of an interference pattern
between the evanescent waves, that this pattern can be optimised to effectively
cancel out the evanescent wave fieeld. This interference pattern arises from a phase
shift of � radians experienced by some of the evanescent waves, with respect to
the others. The significance of this in hydrodynamics is that it explains the existence
of negative added mass. The application for this knowledge far out reaches
the topic of reducing the distortion in a wave tank. The ability to minimise the
added mass of a wavemaker has a great deal of potential in both active absorbing
wavemakers and wave energy conversion. For active absorbing wavemakers, the
minimisation of added mass may be useful in the absorption of unwanted waves
which can be particularly troublesome at high frequencies.
The concept of designing the geometry of a wavemaker to simply match the
motion of the
uid particles has long been proposed; however, the difficulty with
designing such a wavemaker is that the ideal geometry is frequency dependent.
Hence, a design that eliminates the evanescent waves at one particular frequency
will not be able to do so for other frequencies. An investigation into the design of
a segmented wavemaker is presented here, as its geometry can easily be adjusted
to suit different frequencies.
The wavemaker theory for the multi-body problem of the segmented wavemaker
is developed, and a new aspect of wavemaker theory that predicts a phase
shift of � radians in some of the evanescent waves is presented for the first time.
A hypothesis is put forward, and then investigated, proposing that this phase
shift can be exploited to create an interference pattern that can effectively cancel
out the evanescent waves. The hydrodynamics of the segmented wavemaker were
constrained using the Newton-Euler equations of motion with Eliminated Constraints
(NE-EC). This approach facilitated a comparison between wavemakers
with multiple degrees of freedom and traditional wavemakers with a single degree
of freedom.

contamination of test results, often a considerable distance must be left between
the wavemaker and the test area. This space requirement may be costly for small
research groups or companies who wish to have a facility to perform some basic
proof-of-concept tests in-house, but are restricted for space. The initial aim of
this project was to develop a wavemaker which minimised this space requirement
over a large range of frequencies. The exploration into the behaviour of evanescent
waves from the point of view of the fundamentals of hydrodynamics has been
very enlightening. It became clear with the discovery of an interference pattern
between the evanescent waves, that this pattern can be optimised to effectively
cancel out the evanescent wave fieeld. This interference pattern arises from a phase
shift of � radians experienced by some of the evanescent waves, with respect to
the others. The significance of this in hydrodynamics is that it explains the existence
of negative added mass. The application for this knowledge far out reaches
the topic of reducing the distortion in a wave tank. The ability to minimise the
added mass of a wavemaker has a great deal of potential in both active absorbing
wavemakers and wave energy conversion. For active absorbing wavemakers, the
minimisation of added mass may be useful in the absorption of unwanted waves
which can be particularly troublesome at high frequencies.
The concept of designing the geometry of a wavemaker to simply match the
motion of the
uid particles has long been proposed; however, the difficulty with
designing such a wavemaker is that the ideal geometry is frequency dependent.
Hence, a design that eliminates the evanescent waves at one particular frequency
will not be able to do so for other frequencies. An investigation into the design of
a segmented wavemaker is presented here, as its geometry can easily be adjusted
to suit different frequencies.
The wavemaker theory for the multi-body problem of the segmented wavemaker
is developed, and a new aspect of wavemaker theory that predicts a phase
shift of � radians in some of the evanescent waves is presented for the first time.
A hypothesis is put forward, and then investigated, proposing that this phase
shift can be exploited to create an interference pattern that can effectively cancel
out the evanescent waves. The hydrodynamics of the segmented wavemaker were
constrained using the Newton-Euler equations of motion with Eliminated Constraints
(NE-EC). This approach facilitated a comparison between wavemakers
with multiple degrees of freedom and traditional wavemakers with a single degree
of freedom.

▼ The conventional atomic force microscope (AFM) is equipped with a single optical detection system. Probe-sample separation is determined in an independent deflection with respect to AFM z-translation experiment. This method of determining probe-surface separation is relative, susceptible to drift and does not provide real time separation information. The
evanescent wave atomic force microscope (EW-AFM) utilizes a second, independent detection system to determine absolute probe-surface separation in real time. The EW-AFM can simultaneously acquire real-time force and probe-sample separation information using the optical lever and
evanescent scattering detection systems, respectively. The EW-AFM may be configured with feedback on the optical-lever system for constant force applications or with feedback on
evanescent wave scattering intensity for constant height applications.
Scattering of the
evanescent wave exponential decay profile is used to determine probe-surface separation. Sub-micron sized dielectric and metallic probes show exponential scattering profiles, micron sized polystyrene and borosilicate microspheres show non-exponential profiles when they are affixed beneath the cantilever tip. By affixing the microspheres to the end of the AFM cantilever exponential and non-exponential profiles were observed.
The EW-AFM can be used to conduct force-distance and imaging experiments. The EW-AFM was used to measure the thickness of surfactant bilayers formed at the silica-solution interface using silicon nitride AFM tips. The presence of a refractive index difference between the surfactant bilayer and the solution does not influence the accuracy of the surfactant bilayer thickness measurement. The EW-AFM was used to scan a 2 x 2 micron area in constant height mode. The probe was brought to within 6 nanometers of a planar dielectric surface using the
evanescent wave intensity as a height reference with accuracy of ± 1 nm. This capability may be utilized to observe charge heterogeneity at the solid-liquid interface with nanometer lateral resolution or to map chemical functional group heterogeneity based on perturbations to the electrical double layer.
The EW-AFM
evanescent scattering system has an absolute separation resolution of 0.3 nm compared to 1.0 nm relative separation resolution for the optical lever system. In constant scattering (constant height) mode the real time separation precision is about 2 nm.

▼ In this dissertation, we present the development of a novel, compact and highly sensitive waveguide Mach-Zehnder interferometer to measure methane dissolved in water. Methane is a greenhouse gas, like carbon dioxide, and is emitted from both natural sources and human activities. Due to the challenges to measure dissolved methane in the sea and the vast area it covers, much of the methane cycle is unknown. In the last couple of years, there has been an up-swing in the development of subsea methane sensors. These high-end sensors rely on successfully separating the dissolved gas from the water with a membrane before the measurements, effecting the limit of detection, response time and it may give rise to hysteresis effects. Alternatively, samples can be transported to an on-shore laboratory, which can be time-consuming and expensive.
We developed a methane sensor with the possibilities of direct and in-situ detection of methane with a relatively cheap and compact optical sensor-chip. A methane sensitive layer, consisting of a host-polymer and cryptophane-A, is deposited onto the chip. Cryptophane-A is a supra-molecular compound that can entrap methane molecules within its structure and thus, induce a change in the refractive index of the host-polymer. This change is detected by the
evanescent field from the waveguide, in the sensing arm of the interferometer. Thus, with a change in refractive index in the sensitive layer, a phase change between the reference and the sensing arms of the interferometer is obtained.
For obtaining optimal design, simulations were made for shallow silicon nitride rib waveguides with respect to the sensitivity as function of refractive index and the mode-behaviour of the waveguide. Once the design had been established, the waveguides were fabricated externally, with a core thickness of 150 nm, a rib height of 5 nm, rib widths of 1.5, 2 and 3 μm and sensing lengths of 1, 2 and 3 cm. The propagation losses were measured and simulated for tantalum pentoxide (similar to silicon nitride) strip and rib waveguides, to find the dependence of the propagation losses on the waveguide width. The sensitivity of the sensor was characterised with a diluted acid (HCl) and, in a separate measurement, by changing the temperature of the sensor coated with a polymer (PDMS).
The sensor was combined with a methane sensitive layer of styrene acrylonitrile (SAN) and cryptophane-A, to detect methane gas. The sensitive layer showed a 17-folded sensitivity increase with a cryptophane-A to SAN ratio of 1:9. Methane gas was measured in the range of 300 ppm to 4.4%(v/v), with a detection limit of 17 ppm. Finally, the sensor was tested with methane in water. It was found that when the sensitive layer was exposed to water, the SAN polymer showed fractures along the surface. In an effort to circumvent the problem, a protecting layer of PDMS was deposited directly onto the SAN layer. However, after some time bubble structures appeared within the layer after exposure to water. Despite this, dissolved methane was…

▼ In recent years, major research funding and commercial development has been going toward the production and characterization of increasingly useful nanomaterials. These materials such as quantum dots, nanoparticles, and thin films can increase the efficiency of solar panels, create new treatments for cancer, and vastly improve the detection capabilities for various optical sensors for biosensing. Unfortunately, to date, very few methods of characterizing these types of materials exist such as scanning electron microscopy and ellipsometry. These techniques are prohibitively expensive, cannot be used with all materials, and require rigorous preparation schemes before scanning. Therefore, a new method to characterize thin films and detect the properties of nanomaterials is needed. This study proposes a newly revived method, Total Internal Reflection Photoacoustic Spectroscopy, along with related techniques, to deliver cost effective characterization and detection for nanomaterials and thin films.

▼ In this dissertation a fabrication process is
developed to reliably create suspended waveguides with optical
grating features. Two potential applications for suspended
waveguides with optical gratings are described,
evanescent field
sensors and stimulated Brillouin scattering lasers, along with
procedures for design and fabrication of the devices. Development
the of fabrication process is described in detail, to explain each
choice of material and fabrication method. The optimized
fabrication process is presented along with the full parameters and
fabrication techniques used. Suspended optical gratings are
fabricated successfully using this method, reliably creating
suspensions of up to 1mm in length, ranging from 1μm to 5μm in
width, and 400-450nm thick. The waveguides are optically
characterized, revealing significant spectral features as a result
of optically induced defects on the waveguides. These defects and
their effects are thoroughly characterized through numerical
modeling. Two methods to bypass the issues caused by these defects
are presented: increased lithography resolution to create single
mode or defect free waveguides, or the use of a high index cladding
layer to force even large scale waveguides into single mode
operation. Time resolved transmission measurements, using the
defects to create stochastic spectral features, are completed as a
proof of concept for these structures use as
evanescent field
sensors.

▼ Accurate diagnosis of active tuberculosis is
required to improve treatment, reduce transmission of the disease
and control the emergence of drug resistance. A rapid and reliable
test would make a considerable contribution to the management of
the TB epidemic, especially in HIV-burdened and resource-poor
countries where access to diagnostic laboratories are limited.
Surrogate marker antibody detection to mycobacterial lipid cell
wall antigens gave promising results, in particular with cord
factor. The specific advantage of using mycolic acids as lipid
antigens in comparison to protein antigens is that mycolic acid is
a CD1 restricted antigen with the ability to induce proliferation
of CD4/CD8 double negative T-cells, which may explain the sustained
antibody production in AIDS patients. Traditional end-point assays
to detect anti-MA antibodies showed an unacceptable number of false
positive and negative test results. Here a much improved biosensor
method (the MARTI-assay, i.e. Mycolic acid Antibody Real-Time
Inhibition assay) was developed to detect antibodies to mycolic
acid in patient sera as surrogate markers of active tuberculosis.
The test was assessed on an IAsys optical biosensor and gave an
accuracy of 82%. The technology was transferred to an SPR (ESPRIT)
biosensor to economise and simplify the assay. Mycolic acid
containing liposomes were immobilized on the SPR gold surface
pre-coated with octadecanethiol. The following parameters were
optimized on the ESPRIT biosensor to enable reliable TB diagnosis:
effect of degassed buffer, saponin blocking, first exposure to
serum at low concentration and second exposure to antigen inhibited
serum at high concentration. The IAsys biosensor system has a
weakness in the double channel cuvette system, in which the
channels often do not give matching results, while being ten times
more expensive than the gold discs provided for the ESPRIT
biosensor. The ESPRIT biosensor is provided with an adjustable
laser setting to compensate for differences in the channel readings
as well as an automated fluidic system that reduces variance from
one sample to the next. First indications are that the test can
also be used for prognosis of TB during treatment. It is hoped that
the ESPRIT biosensor will improve the accuracy of the test to more
than 90%. If the MARTI-assay technology could be made amenable for
high throughput screening, it may provide the solution to the
serodiagnosis of tuberculosis and monitoring of progress during TB
treatment both in adult and children, thereby reducing the spread
of TB within the communities.

▼ Nanotechnology has become so widely used it can be found in every aspect of life, from cell-phones and computers, to cars, and even athletic socks. As it permeates so many markets, the need for supplemental technologies has also increased. One such needed technology is in the area of nanoscale characterization. Current imaging methods are advanced; however, they do not have the capabilities to characterize the size, shape, composition, and arrangement of nanostructures and nanoparticles in a real-time, unobtrusive manner. The Polarized-Surface-Wave-Scattering system (PSWSS) is a method being researched at the University of Utah that can provide such characterization,although in order for the PSWSS to function accurately through inversion techniques, a predictive forward model must be developed and validated. This work explores thediscrete dipole approximation with surface interaction (DDA-SI), an open source MATLAB toolbox, as a predictive model to calculate electromagnetic scattering by objects on a surface illuminated by an evanescent wave generated by total internal reflection (TIR). Far-field scattering predictions via DDA-SI are validated against scaled microwave experimental results for two objects on a surface: a sphere with a diameter ofA/1.92 and a cube with a side length of A/1.785, where A refers to the wavelength. A good agreement between experiments and simulations is observed, especially when modified Fresnel reflection coefficients are employed by DDA-SI. Programs to calculate theamplitude scattering matrix and Mueller matrix elements have been also been created.Additionally, the sensitivity of four Mueller matrix elements (Mu, M 12, Mu, and M22) to the particle size, material (gold and silver), shape (sphere and cube), and interparticle spacing, is analyzed. It is found that these four elements are sensitive to changes in shapeand interparticle spacing, whereas prove insufficient to difference in material and sizes smaller than one-half the wavelength of incident light. Findings show that DDA-SI is a strong forward model for calculation of far-field scattering, but for characterization purposes, other Mueller matrix elements that measure changes in circular polarization must be analyzed. Future research efforts will include more extensive experimentalmeasurements and calibration, as well as creation of a scattering profile database, and further sensitivity analysis using DDA-SI.

▼ Nesse trabalho, propomos uma modificação da técnica de caracterização de filmes conhecida por m-line para o desenvolvimento de um refratômetro para gases e líquidos. O principio dessa técnica consiste no acoplamento de ondas evanescentes em guias de ondas planares obtidos via o fenômeno da reflexão total interna frustrada através de dispositivos acopladores. Observa-se experimentalmente, após incidir um feixe de laser contínuo na base do acoplador óptico, uma grande atenuação da radiação refletida para determinados ângulos de incidência, que é justamente a radiação acoplada nos modos permitidos pelo guia de onda. Medindo-se os valores desses ângulos e usando a teoria de acoplamento, é possível determinar as características desconhecidas do sistema. Esse sistema consiste de um acoplador óptico semicircular de alto índice de refração em cuja base foram depositados, via evaporação, um filme de dióxido de silício (SiO2) e outro de dióxido de zircônio (ZrO2). Ou seja, o sistema resume-se a dois meios finitos (filmes) prensados entre dois meios semi-infinitos (prisma e amostra). Como a espessura dos filmes e os índices de refração complexos dos filmes e do prisma são conhecidos, a única variável é o índice de refração do quarto meio, que é a amostra da qual se deseja medir o índice de refração. Estudamos a influência que cada um dos parâmetros externos exerce sobre o perfil refletido, tais como comprimento de onda e polarização da radiação incidente, espessuras e índices de refração dos filmes e o formato dos dispositivos acopladores. Descrevemos o comportamento do sistema quando o feixe incidente possui perfil gaussiano, que é perfil dos lasers usualmente usados em pesquisa. As espessuras das camadas de SiO2 e de ZrO2 foram otimizadas tendo em vista a faixa dos valores do índice de refração das amostras que se deseja medir. A otimização do sistema é obtida via teoria de guiamento de radiação em guias de ondas planares para o caso de quatro meios. Para a aquisição e tratamento dos dados desenvolvemos um programa na plataforma LabVIEW® que processa a imagem detectada por uma câmera CCD no visível, possibilitando o acompanhamento da variação do feixe refletido em função da variação do índice de refração da amostra. Assim, além de determinar ponto a ponto a variação do perfil refletido, é possível determinar a dinâmica em que esse efeito se realiza, gerando possibilidades de aplicação da técnica em áreas relacionadas à dinâmica química e bioquímica. Para confirmação da efetividade da técnica, realizamos medidas da variação do índice de refração do ar em função da umidade relativa, temperatura, pressão e para soluções de glicose. O sistema demonstrou sensitividade suficiente para acompanhar mudanças do índice de refração do ar da ordem de 10-6.

▼ Accurate diagnosis of active tuberculosis is required to
improve treatment, reduce transmission of the disease and control
the emergence of drug resistance. A rapid and reliable test would
make a considerable contribution to the management of the TB
epidemic, especially in HIV-burdened and resource-poor countries
where access to diagnostic laboratories are limited. Surrogate
marker antibody detection to mycobacterial lipid cell wall antigens
gave promising results, in particular with cord factor. The
specific advantage of using mycolic acids as lipid antigens in
comparison to protein antigens is that mycolic acid is a CD1
restricted antigen with the ability to induce proliferation of
CD4/CD8 double negative T-cells, which may explain the sustained
antibody production in AIDS patients. Traditional end-point assays
to detect anti-MA antibodies showed an unacceptable number of false
positive and negative test results. Here a much improved biosensor
method (the MARTI-assay, i.e. Mycolic acid Antibody Real-Time
Inhibition assay) was developed to detect antibodies to mycolic
acid in patient sera as surrogate markers of active tuberculosis.
The test was assessed on an IAsys optical biosensor and gave an
accuracy of 82%. The technology was transferred to an SPR (ESPRIT)
biosensor to economise and simplify the assay. Mycolic acid
containing liposomes were immobilized on the SPR gold surface
pre-coated with octadecanethiol. The following parameters were
optimized on the ESPRIT biosensor to enable reliable TB diagnosis:
effect of degassed buffer, saponin blocking, first exposure to
serum at low concentration and second exposure to antigen inhibited
serum at high concentration. The IAsys biosensor system has a
weakness in the double channel cuvette system, in which the
channels often do not give matching results, while being ten times
more expensive than the gold discs provided for the ESPRIT
biosensor. The ESPRIT biosensor is provided with an adjustable
laser setting to compensate for differences in the channel readings
as well as an automated fluidic system that reduces variance from
one sample to the next. First indications are that the test can
also be used for prognosis of TB during treatment. It is hoped that
the ESPRIT biosensor will improve the accuracy of the test to more
than 90%. If the MARTI-assay technology could be made amenable for
high throughput screening, it may provide the solution to the
serodiagnosis of tuberculosis and monitoring of progress during TB
treatment both in adult and children, thereby reducing the spread
of TB within the communities.

▼ The manipulation of micrometer or nanometer scale objects based on light-matter interaction has been a hot topic ever since Ashkin proposed in 1986 the ¡°optical tweezers¡±, which realized optical trapping and manipulation of polystyrene latex micro-particles through focused laser beams. Notably, Kawata et al. manipulated micrometer scale spheres near the surface of a prism based on radiation pressure generated by total internal reflection-induced
evanescent field. Righini et al. introduced ¡°surface plasmon tweezers¡± by trapping single microparticles on patterned gold structures under surface plasmon excitation. There remains much work to be done, however, in areas including patterning techniques and dynamics study of manipulated objects.
The disclosed thesis contributes to the breadth of knowledge on optical manipulation. Key developments in the field were first reviewed. From this background ¡®surface plasmon tweezers¡¯ were devised to trap and arrange polystyrene beads. The aggregation of the beads was driven by the combination of force and thermal gradient, and the bulk migration of said beads by radiation pressure or scattering force along the light propagation direction. The dynamics of the beads were also found to be
subject to thermal convection. Lastly, a tunable, surface plasmon-based patterning technique was proposed.

▼ Near-membrane and trans-membrane proteins and their interactions with the extracellular matrix (ECM) can yield valuable information about cell dynamics. However, advances in the field of nanoscale cellular processes have been hindered, in part, due to limits imposed by current technology. In this work, a novel
evanescent field (EF) imaging technique is designed, modeled, created and tested for near-field imaging in the apical surface of cells. This technique and Förster resonance energy transfer (FRET) were used to investigate interactions between integrins on the cell surface and the ECM protein, fibronectin. The goal was to monitor changes in the integrin density at the cell surface as a function of clustering after binding to fibronectin on the microsphere surface. For the EF technique, quantum dot (QD)-embedded polystyrene microspheres were used to couple light into whispering gallery modes (WGMs) inside the microspheres; the resulting EF at the surface of the microsphere was used as a near-field excitation source with ~50 nm axial resolution for exciting fluorescently-labeled integrins. For FRET measurements (~10 nm axial resolution), QDs (donors) were coated on the surface of microspheres and energy transfer to red fluorescent protein (RFP)-integrin constructs (acceptors) studied. In both techniques, the QD-modified microspheres were mounted on atomic force microscope (AFM) cantilevers, functionalized with fibronectin, and brought into contact with fluorescently-labeled HeLa or vascular smooth muscle (VSM) cells. The results obtained from both methods show the clustering and activity of the integrins and are in good agreement with each other.
Amsterdam discrete dipole approximation (ADDA) was used to study the effects of inhomogeneous surrounding refractive index on the quality factor and position of the WGMs due to the attachment of a microsphere to an AFM cantilever. WGMs of various QD-embedded microspheres mounted on AFM cantilevers were experimentally measured and shown to be consistent with the model.

▼ Immobilization of photosynthetic cultures has been used to generate biofuels and high value compounds through direct conversion of CO2 and water using sunlight. Compared with suspended cultures, immobilized bacteria can achieve much higher densities resulting in greater areal productivity. Limitations exist however, on the density that can be reached without compromising access to light and other nutrients.
In this thesis an optofluidic approach to overcoming the challenge of light delivery to high density cultures of cyanobacteria is described and proof of concept experiments presented. This approach uses optical waveguides to deliver light to cells through bacterial interaction with the evanescent field and is tailored to meet each cell's need for light and nutrients. Experiments presented here demonstrate biofilm proliferation in the presence of evanescent fields. Illumination of surfaces by surface plasmon enhanced evanescent fields is also shown to be an effective and potentially useful technique to grow biofilms within optofluidic architectures.

▼ Growing concerns for quality of water, food and beverages in developing and developed countries drive sizeable markets for mass-producible, low cost devices that can measure the concentration of contaminant chemicals in water, food, and beverages rapidly and accurately. Several fiber-optic enzymatic biosensors have been reported for these applications, but they exhibit very strong presence of scattered excitation light in the signal for sensing, requiring expensive thin-film filters, and their non-planar structure makes them challenging to mass-produce. Several other planar optical waveguide-based biosensors prove to be relatively costly and more fragile due to constituent materials and the techniques involved in their fabrication. So, a plastic total internal reflection (TIR)-based low cost, low scatter, field-portable device for enzymatic biosensors is fabricated and demonstrated. The design concept of the TIR-based photoluminescent enzymatic biosensor device is explained. An analysis of economical materials with appropriate optical and chemical properties is presented. PMMA and PDMS are found to be appropriate due to their high chemical resistance, low cost, high optical transmittance and low auto-fluorescence. The techniques and procedures used for device fabrication are discussed. The device incorporated a PMMA-based optical waveguide core and PDMS-based fluid cell with simple multi-mode fiber-optics using cost-effective fabrication techniques like molding and surface modification. Several techniques of robustly depositing photoluminescent dyes on PMMA core surface are discussed. A pH-sensitive fluorescent dye, fluoresceinamine, and an O2-sensitive phosphorescent dye, Ru(dpp) both are successfully deposited using Si-adhesive gel-based as well as HydroThane-based deposition methods. Two different types of pH-sensors using two different techniques of depositing fluoresceinamine are demonstrated. Also, the effect of concentration of fluoresceinamine-dye molecules on fluorescence intensity and scattered excitation light intensity is investigated. The fluorescence intensity to the scattered excitation light intensity ratio for dye deposition is found to increase with increase in concentration. However, both the absolute fluorescence intensity and absolute scatter intensity are found to decrease in different amounts with an increase in concentration. An enzymatic hydrogen peroxide (H2O2) sensor is made and demonstrated by depositing Ruthenium-based phosphorescent dye (Ru(dpp)3) and catalase-enzyme on the surface of the waveguide core. The O2-sensitive phosphorescence of Ru(dpp)3 is used as a transduction signal and the catalase-enzyme is used as a bio-component for sensing. The H2O2 sensor exhibits a phosphorescence signal to scattered excitation light ratio of 100±18 without filtering. The unfiltered device demonstrates a detection limit of (2.20±0.6) µM with the linear range from 200µM to 20mM. An enzymatic lactose sensor is designed and characterized using Si-adhesive gel based Ru(dpp)3 deposition and oxidase…

▼ Photosynthetic biofilms have much higher cell density than suspended cultures and when grown in a stacked waveguide configuration, can have orders of magnitude higher areal productivity. Evanescent and plasmonic growth of biofilm cultures have been demonstrated, solving issues with light penetration impeding growth, but thus far the technology has been limited to biofuel production applications.
In this thesis, plasmonically excited cyanobacterial biofilms are used to produce electrical power in a photosynthetic-plasmonic-voltaic device. This approach uses red lasers to deliver light to cells via an optical waveguide through the generation of surface plasmons at the interface between a metal and dielectric, in this case a glass-gold-air interface. This gold film serves a dual purpose as a current collector for electrons generated at the cell surface. Experiments presented here demonstrate positive power output light response under both direct light and plasmonic excitation and produced equivalent power output of 6 uW/m2 under similar light power intensities.

▼ Silicon photonics has garnered plenty of interests from both the academia and industry due to its high-speed transmission potential as well as sensing capability to complement silicon electronics. This has led to significant growth on the former, valuing at US 626.8M in 2017 and is expected to grow 3-fold to US 1,988.2M by 2023, based on data from MarketsandMarkets™. Silicon photonics’ huge potential has led to worldwide attention on fundamental research, photonic circuit designs and device fabrication technologies. However, as with silicon electronics in its early years, the silicon photonics industry today is extremely fragmented with various chip designs and layouts. Most silicon photonic devices fabricated are not able to reach the hand of consumers, due to a lack of information related to packaging design rules, components and processes. The importance of packaging technologies, which play a crucial role in turning photonic circuits and devices into the final product that end users can used in their daily lives, has been overlooked and understudied. This thesis aims to – 1. fill the missing gap by adapting existing electronics packaging techniques, 2. assess its scalability, 3. assess supply chain integration and finally 4. develop unique packaging approaches specifically for silicon photonics. The first section focused on high density packaging components and processes using University of California, Berkeley’s state-of-the-art silicon photonic MEMS optical switches as test devices. Three test vehicles were developed using (1) via-less ceramic and (2) spring-contacted electrical interposers for 2D integration and (3) through-glass-via electrical interposers for 2.5D heterogeneous integration. A high density (1) lidless fibre array and (2) a 2D optical interposer, which allows pitch-reduction of optical waveguides were also developed in this thesis. Together, these components demonstrated the world’s first silicon 2 photonic MEMS optical switch package and subsequently the highest density silicon photonic packaging components with 512 electrical I/Os and 272 optical I/Os. The second section then moved away from active optical coupling that was used in the former, investigating instead passive optical packaging concepts for the future. Two approaches were investigated - (1) grating-to-grating and (2)
evanescent couplings. The former allows the development of pluggable packages, separating fibre coupling away from the device while the latter allows simultaneous optical and electrical packaging on a glass wafer in a single process. Lastly, the knowhow and concepts developed in this thesis were compiled into packaging design rules and subsequently introduced into H2020-MORPHIC, PIXAPP packaging training courses (as a trainer) and other packaging projects within the group.

▼ This thesis describes the application of a custom
designed λ/4 resonant coaxial probe to measurements of the complex
permittivity of in vitro freshly excised porcine skin tissue. The
dielectric properties of the organic material within the near field
of the tip of the probe frustrates the electric field and
measurably changes the resonant frequency and quality factor Q of
the coaxial sensor, where the change in resonant frequency and
quality factor of a tuned resonance is measured as a function of
tip-sample separation. The design of the probe enables better
spatial resolution than previously developed probes. The following
studies were performed: (1) measurement of the complex permittivity
of porcine tissue over a range of frequencies revealed values
consistent with published literature; (2) the change in quality
factor from the probe measurements was compared to a visual
microscope analysis of histological slices from the same skin
location, indicating that subsurface structures such as capillary
beds, ducts of exocrine sweat glands, and vein lumen ducts can be
detected; and (3) measurements of the dielectric properties of a
puncture wound and several burn lesions of varying severity
revealed easily detectable changes, indicating that the probe has
potential for evaluating and monitoring skin conditions. In
addition, a new quantitative two point relationship between the
real and imaginary parts of the materials complex permittivity
related to the resonant frequency and quality factor shift using
the method of images is developed, presented, and used in the above
described skin studies. The two-point model describing the probe
tip-sample interaction is capable of producing quantitative complex
permittivity values for organic and biological
materials.

▼ In this thesis electromagnetic near fields in nanoscale structures are investigated. The optical near field is characterized by a strong presence of evanescent (non-radiative) waves which are significant only within the distance of the wavelength of light from the surface of a light emitting or scattering object. These waves play an essential role in the design and characterization of components for nanophotonics and exhibit phenomena not encountered in the conventional far-field optics. In this thesis, specific optical systems at sub-wavelength scale are studied. In two of them the electromagnetic field is assumed to be deterministic whereas in two other systems the random nature of light is considered. One specific aim of this work is to assess the role of partial polarization and partial spatial coherence in electromagnetic near fields. This type of analysis necessitates the coherence theory of general, non-planar, three-dimensional (3D) electromagnetic fields which has not been available until very recently. The new concepts of electromagnetic coherence theory for 3D fields, such as 3D degree of polarization, electromagnetic degree of coherence, and electromagnetic theory of coherent modes, are applied to study partial polarization and partial spatial coherence of random near fields. Furthermore, the first explicit 3D coherent-mode representation is derived for a certain type of electromagnetic fields. The topics which are included in this thesis are as follows: Transmission of partially polarized light through a scanning near-field probe tip, is studied in terms of the 3D degree of polarization. The enhanced transmission of light through a single sub-wavelength slit on a metal film is investigated, and the resonance behavior of its transmission spectrum is analyzed. The electromagnetic coherence theory is applied to study surface plasmon resonances in metallic nanocylinders, and their effect on the 3D degree of polarization, the electromagnetic degree of coherence, as well as on the electromagnetic energy transfer in the optical near field is assessed. Also the fluorescence resonance energy transfer (FRET) mediated by plasmon resonant metallic nanoparticles is addressed.
Väitöskirjassa tarkastellaan sähkömagneettisia lähikenttiä nanorakenteissa. Optisille lähikentille on luonteenomaista vaimenevien (ei-säteilevien) aaltokomponenttien hallitseva vaikutus kokonaiskenttään. Vaimenevat aallot ovat merkittäviä vain alle valon aallonpituuden etäisyydellä kentän lähteestä ja niiden huomioiminen on olennaista tutkittaessa ja suunniteltaessa nano-optisia komponentteja. Lisäksi vaimenevista aalloista johtuen lähikentissä esiintyy optisia ilmiöitä, joita ei tavata kaukana lähteestä. Tässä työssä tarkastellaan sähkömagneettista kenttää tietyissä alle aallonpituuden mittakaavan rakenteissa. Kahdessa rakenteessa sähkömagneettinen kenttä oletetaan täysin deterministiseksi, kun taas kahdessa muussa rakenteessa kentän satunnainen luonne huomioidaan.

▼ An optical fiber humidity sensor has been devised using a porous sol-gel silica (PSGS) coating as a transducer.
Evanescent wave scattering (EWS) in the PSGS coating. PSGS particles are highly hydrophilic and have a strong tendency to absorb water molecules from the surrounding environment. The absorbed water molecules form a thin layer on the inner surface of the pores inside the porous silica and enhance EWS, from which an indicatory signal can be obtained. The humidity sensor presented in this thesis has a fast response, is reversible, low cost, and has a broad dynamic relative humidity range from 3.6?0-6% to 100% or humidity range from 1.2ppm to 30000ppm. Because of its multiple advantages, including immunity to electromagnetic interference, resistance to corrosive environments, and high sensitivity, this humidity sensor has various applications. In soil moisture sensing, this humidity sensor can avoid the interference caused by compounds in soil water. For electrical transformer moisture sensing, this humidity sensor can avoid the effect of electromagnetic fields.

▼ Outbreaks of bacteria have caused many problems over the last few years and are a major public health concern. Bacteria are now affecting our lives in many ways to a more severe extent, from contaminated food in markets to polluted water. There are some devices available which detect bacteria, however, all of them can only be used in the lab condition and are very expensive. This research is aimed at the development of a biomedical sensor which is capable of monitoring bacteria, especially focusing on diagnosing colorectal anastomotic leakage (AL) in patients at an early stage by detecting the existence of E. coli in the drain fluid. The occurrence of AL in patients after colon surgery is high and is cause for concern as it can lead to severe consequences, such as morbidity or even mortality. Therefore, there is a vital need for an efficient, on-line bedside tool to monitor the bacteria in the leakage: a diagnostic on-line device that is accurate, cost-effective, and ideally operates in an easy plug-and-play fashion which is beneficial for practical application.

▼ Elektrotehničko inženjerstvo - Fotonika /
Electrical Engineering - Photonics
Optički senzori su deo mnogobrojnih sistema u
industriji, transportu, telekomunikacijama, medicini i nauci.
Koriste se za merenje temperature, pritiska, istezanja, indeksa
prelamanja okolne sredine i indirektno za merenje koncentracije
gasova i tečnosti, vlažnosti i drugog. Uglavnom zahvaljujući naglom
razvoju optičkih telekomunikacionih tehnologija, razvoj optičkih
senzora pratio je opšti trend smanjivanja i integracija ka malim,
robusnim i prenosivim urađajima. Pri tom su se izdvojila dva
osnovna tipa senzora: senzori na bazi optičkih vlakana i
integrisani senzori, koji su dalje funkcionalizovani hemijskim
putem i korišćenjem nanotehnologija. Razvoj metoda za proizvodnju
minijaturnih senzora i tankih filmova koji se nanose na površinu
senzora je značajno uticao na razvoj optičkih senzora. U
distertaciji su istraživani senzori na bazi integrisanih svetlosnih
talasovoda funkcionalizovani tankim poroznim filmom. Princip
detekcije je interakcija merene tečnosti ili gasa sa evanescentnim
elektromagnetim poljem. Kod gasova je dominantna rezonantna
apsorpcija svetlosti, a kod tečnosti promena profila i propagacione
konstante moda usled promena indeksa prelamanja tečnosti. U oba
slučaja poroznost filma omogućava veće preklapanje polja moda sa
fluidom koji se meri i time osetljivost senzora. Ova teza se bavi
proučavanjem uticaja parametara tankog filma na performanse
senzora, osetljivost i opseg, kao i optimizacijom geometrije
senzora u cilju dobijanja najviše osetljivosti. Pritom su korišćeni
parametri tankih filmova i njihove varijacije određeni
eksperimentalno. Rezultat rada su predlozi i dizajn ovih tipova
optičkih senzora pogodnih karakteristika za određivanje
koncentracije fluida upotrebom poznatih nanotehnologija. Pokazano
je da se najbolja osetljivost senzora gasa javlja u slučaju
talasovodnih struktura koje podržavaju modove pretežno lokalizovane
u oblasti tankog poroznog filma. Takođe je pokazano da se
korišćenjem poroznih filmova osetvljivost senzora povećava 20 puta
u odnosu na neporozne, kao i da male varijacije debljine i
poroznosti filma od 1% značajno smanjuju osetljivost senzora.
Proračuni su izvedeni za senzor ugljen-dioksida u bliskom
infra-crvenom opsegu...

▼ Recently, Giovannetti et al. successfully demonstrated that some metals (such as Cu and Au) only have weak van der waals interaction with graphene and thus can only form weak bonding without severely shifting graphene’s band structure, which describes the energies range of the electrons in the material. Therefore, this opens up windows for graphene enhancement without greatly changing its properties. Furthermore, Zhou et al. later suggested the possibility of self-assembling periodic arrays of alkali atoms on graphene. In our group, graphene thin films fabricated in a cost effective way using solution-processed methods have been used extensively, including decorating graphene thin films with metallic nanoparticles for optical enhancement. Motivated by these experiments, our study reports a facile fabrication method for copper nanoparticle (Cu-np) superlattice, which is a periodic structure of copper-nanoparticle lines. This fabrication is based on thermal evaporation of ultrathin layers of copper. These copper layers are deposited on solution-processed thin films formed by few-layer graphene platelets. We show that the annealing of these systems in nitrogen without previous exposure to air prompts the heterogeneous nucleation of the Cu layer into nanoparticle superlattices. And these nanoparticles self-assemble along specific crystallographic directions of graphene. Theoretical calculations suggest the lowest formation energy for Cu-nanoparticle arrays forming along armchair directions, indicating that their self-assembly is energetically more favorable. The possibility of using these superlattices in evanescent waveguiding devices is explored by scanning near-field optical microscopy. The light-confining properties of our systems in the near field indicate that our nanoparticle superlattices are poised to satisfy the technological demands required by nanophotonics devices.
