▼ Integration of complex
optical functionalities with high performance will lead to a huge development in the field of nanophotonics for a broad range of applications. Silicon photonics is currently the leading technology for the implementation of low-cost photonic integrated devices. The great potential of this technology relies on its compatibility with the mature silicon integrated circuits manufacturing based on complementary metal-oxide semiconductor (CMOS) processes widely used in microelectronic industry and the availability of high quality silicon-on-insulator wafers, an ideal platform for creating planar waveguide circuits that offers strong
optical confinement due to the high index contrast between silicon (n=3.45) and silicon dioxide (n=1.45). In order to keep improving the performance of photonic devices on silicon, the integration of CMOS compatible materials with unique properties shows up as an excellent opportunity to overcome the current limitations in silicon while offering unprecedented and novel capabilities to the silicon platform. In this way, barium titantate (BaTiO3) stands out as one of the most disruptive candidates. The work developed in this thesis is essentially focused on the design, fabrication and characterization of an electro-optic modulator based on a hybrid BaTiO3 on silicon structure for the implementation of high performance electro-optic functionalities with beyond state-of-the art performance that currently cannot be afforded in silicon photonics technology.; La integración de funcionalidades ópticas con alto rendimiento llevará a un gran desarrollo en el campo de la nanofotónica para un amplio abanico de aplicaciones. Actualmente, la fotónica de silicio es la tecnología líder para la implementación de dispositivos fotónicos integrados a bajo coste. El gran potencial de esta tecnología reside en su compatibilidad con las maduras técnicas de fabricación de circuitos integrados de silicio basadas en los procesos "complementary metal-oxide semiconductor" (CMOS) ampliamente utilizados en la industria microelectrónica y la disponibilidad de disponer de obleas de silicio sobre aislante de alta calidad, una plataforma ideal para crear circuitos de guía de ondas planas que ofrecen un fuerte confinamiento óptico debido al alto contraste índices entre el silicio (n=3,45) y el dióxido de silicio (n=1,45). Para poder mejorar el rendimiento de dispositivos fotónicos en silicio, la integración de materiales con propiedades excepcionales y compatibles con los procesos de fabricación CMOS surge como una excelente oportunidad para superar las actuales limitaciones de la tecnología de silicio al mismo tiempo que ofrece oportunidades novedosas y sin precedentes en la plataforma de silicio. En este sentido, el material titanato de bario (BaTiO3) se postula como uno de los candidatos más prometedores. El trabajo desarrollado en esta tesis está esencialmente enfocado en el diseño, fabricación y caracterización de un modulador electro-óptico basado en una estructura híbrida de BaTiO3 en silicio para la…

▼ Over the past several years, rapid advances in the field of integrated photonics coupled with nanofabrication capabilities have enabled studies of the interaction of light with the mechanics of a variety of physical structures. Concurrently, mechanical resonators have been extensively studied in the MEMS community due to their high quality factors, and have been implemented in a variety of RF filters and oscillators. The combination of MEMS with integrated optomechanical structures can generate a variety of novel devices that can be used for applications in RF-Photonics, timing and optical switching. While there are several demonstrations of electrostatic devices integrated with optomechanical structures, fewer examples exist in the piezoelectric domain. In particular, photonic integration in a piezoelectric material can benefit from some of the traditional strengths associated with this type of actuation, such as the ability to easily scale to higher frequencies of operation by patterning lateral features, the ability to interface with 50Ω electronics and strong electromechanical coupling. In addition, it enables a platform to produce new architectures for photonic-based electronic frequency reference oscillators that incorporate multiple degrees of freedom. This thesis presents the development of a piezoelectrically-actuated acousto-optic modulator in the aluminum nitride (AlN) material system. The process of implementing this device is carried out in five principal stages. First, light coupling from optical fibers to the AlN thin film is demonstrated with the use of on-chip grating couplers, exhibiting a peak insertion loss of -6.6 dB and a high 1 dB bandwidth of 60 nm for operation in the telecommunications C- and L-bands. This is followed by characterization of photonic whispering gallery mode microdisk and microring resonators with optical quality factors on the order of 104. Next, a robust fabrication method combining optical and electron-beam lithography is developed to produce a fully-integrated device preserving the critical features for acoustic and photonic resonators to be colocalized in the same platform. Acousto-optic modulation is demonstrated with the use of a contour mode resonator which drives displacements in the photonic resonator at 653 MHz, corresponding to the mechanical resonance of the composite structure. The modulator is then implemented in an opto-acoustic oscillator loop, for which an initial phase noise of -72 dBc/Hz at 10 kHz offset from the carrier is recorded with a large contribution from thermal noise at the photodetector. Finally, some possibilities to improve the modulator efficiency and oscillator phase noise are provided along with prospects for future work in this area.

▼ There is an ever-increasing demand in bandwidth and data rate in optical communications, internet, sensing, computing, machine learning applications and cloud computing. For chip-level communications, existing complementary metal oxide semiconductor (CMOS) electronic-based solutions are currently challenged and strained to its maximum limit. The maximum speed of the new 5G mobile connection is 10 Gbits/s. When the bit rates increase beyond 10 Gbits/s, copper tracks that carry current between the processing chips severely distort and attenuate the data signal due to parasitic resistance, inductance, and capacitance of the track. To overcome this challenge, the industry is increasingly looking towards silicon photonics as a key technology in next-generation communications systems, and data interconnects.
Silicon photonics is an emerging technology based on silicon chips, where photons (instead of electrons) are used to carry information in a CMOS chip. Photons can carry far more data in less time than electrons because it can be pulsed at higher frequencies than electric currents resulting in high bandwidth. Since both CMOS and silicon photonics are based on silicon, it is possible to integrate photonics circuits and electronic circuits in a single chip. Conventional on-chip silicon photonics-based functional elements such as filters, waveguides, laser sources, modulators and switches are still bulky compared to electronics process technology (14 nm process technology became available in 2014 and 10 nm in 2017) and hence there is a mismatch in the integration. This mismatch in the size of photonic components and transistor gates is a bottleneck in developing functional elements integrated with electronics on a chip. This requirement has recently triggered research on new device technologies where silicon photonics is combined with plasmonics and electro-optic materials to reduce the footprint, energy consumption and insertion loss as well as to increase modulation index (modulators) and the frequency of operation.
This thesis investigates the development of new plasmonic modulators and switches combined with vanadium oxide operating in optical communication wavelengths to reduce the footprint and increase the performance. Further research is carried out to study other suitable plasmonic geometries, which are optimised in optical communication wavelengths.
Optical modulation is at the heart of silicon photonics for on-chip optical communications where there is a trade-off exists among optical loss (attenuation), size and modulation depth, speed and footprint. This demands innovative approaches to research on CMOS compatible novel high-speed modulators for silicon photonics for next-generation communication devices. We first explored the plasmonic slot modulators using Vanadium Dioxide (VO2) as modulating material realised on silicon on insulator (SOI) wafer with 200 nm by 140 nm modulating section within 1 um by 3 um device footprint. By utilising the phase transition property of VO2, the modulator can…

▼ Abstract: Techniques for characterization of photonic devices are presented. The experimental procedures employ ultrafast acquisition of the electromagnetic
optical wave, after its photodetection through direct or coherent reception schemes. The acquired data is digitalized and stored in high-speed memories, resulting in packets suitable for the posterior offline analysis. The developed algorithms allow the extraction of information regarding the dynamic operation of the photonic devices responsible for the
optical carrier generation, modulation, or amplification. By employing this new methodology and interferometric principles, the harmonic distortions on electro-
optical modulators are characterized as a function of their electrical modulation frequency. Therefore, a characterization technique based on the overmodulation analysis was developed, allowing the verification of the signal quality in the time and frequency domains as a function of the properties of the electrical modulation signals. The achieved results show the device frequency limitations, resulting in the increase of its half-wave voltage, as well as some nonlinear effects. Following, the phase and frequency noise in semiconductor lasers under continuous wave operating mode are characterized. The employed technique is based on the
optical carrier coherent reception, mixed with a reference local oscillator, allowing its temporal analysis with an offline algorithm. The achieved results allow a thoughtful insight on the loss of coherence events nature, in addition to the estimation of lasers' linewidth. Finally, the characterization of amplitude, frequency, and phase distortions due to the
optical carrier switching by an electro-
optical space switch based on semiconductor
optical amplifier (SOA), as a function of its operating properties, are discussed. In this sense, the optimum operational region and the desired device characteristics are determined for the switching of an amplitude modulated
optical carrier case. Additionally, the frequency chirp and phase noise, due to SOAs' intrinsic nonlinear behavior, are characterized

▼ Bis(thiourea)cadmium chloride (BTCC) is a novel
semiorganic nonlinear optical (NLO) material for efficient
frequency doubling of Nd:YAG laser. BTCC crystal has good
transmission in the entire visible region and is 110 times more
nonlinear than quartz. Bis(thiourea)cadmium iodide (BTCI) is
another novel semiorganic NLO material found to be a good candidate
for electrooptic modulators. With an aim of discovering new useful
materials, we have grown by the free evaporation method and
characterized pure and mixed crystals of BTCC and BTCI [(BTCC)x
(BTCI)1-x with x = 1.0, 0.8, 0.6, 0.5, 0.4, 0.2 and 0.0] and urea
doped (0.25, 0.50, 0.75 and 1.0 mol% doped) BTCC single crystals.
newline newline Single crystal X-ray diffraction (SXRD) and powder
X-ray diffraction (PXRD) measurements were carried out to
characterize the grown crystals structurally. The important groups
associated with the sample crystals were identified and their
respective bands were assigned by carrying out the Fourier
transform infrared (FTIR) spectral studies. Energy dispersive X-ray
spectra were recorded to understand the chemical composition of the
crystals grown. All the grown mixed crystals were subjected to
thermogravimetric (TG) and differential thermogravimetric analyses
(DTA) inorder to understand the thermal behaviour. Optical
behaviour of the grown crystals were studied by UV-Vis-NIR spectral
analysis and Second Harmonic Generation (SHG) efficiency
measurements. newline newline DC and AC electrical measurements
were carried out by the two probe method and parallel plate
capacitor method respectively. Measurements were carried out at
various temperatures ranging from 30-100and#61616;C. DC
conductivity (and#61555;dc) and DC activation energy (Edc) were
determined. The dielectric parameters (and#61541;r, tan and#61540;
and and#61555;ac) and AC activation energy (Eac) were also
determined.

▼ Silicon photonics is one of the most exciting and fastest growing photonic technologies
in recent years. The salient feature of this technology is its compatibility with the
mature silicon IC manufacturing based on complementary metal-oxide semiconductor
(CMOS) processes widely used in microelectronic industry. Another motivation is the
availability of high-quality silicon-on-insulator (SOI) planar waveguide circuits that
offer strong
optical confinement due to the high index contrast between silicon (n=3.45)
and SiO2 (n=1.45). This opens up miniaturization and very large scale integration of
photonic devices allowing photonic integrated circuits for a wide range of applications
and markets, from
optical telecommunications to bio-photonic devices or precise fibre
sensors.
Optical modulators are key building-blocks for high speed signal transmission
and information processing in any photonic interconnection solution. The work
developed in this thesis, as part of the objectives of the European project HELIOS in
which it is framed, is essentially focused on realizing compact and efficient
modulators
integrated on silicon chips.
The thesis consists of three main chapters as well as the concluding section on the
work accomplished. Chapter one is aimed at giving a general description of the benefits
of using silicon photonics, showing its challenges and opportunities as well as at giving
a deeply overview of all issues related to the electro-optic modulation. Chapter two is
devoted to develop silicon
modulators with high features for digital applications.
Specifically, new
optical structures different to the conventional ones are presented with
the aim of enhancing the modulation performance or at least several critical parameters
in the modulation. Chapter three is dedicated to the analog applications. The concept of
microwave photonics is described as well as different researches carried out in the
analog scope for application in the field of integrated microwave photonics, all of them
using CMOS-compatible electro-optic silicon
modulators which validate the potential of
silicon photonics as a promising approach for enabling the development of integrated
microwave photonics applications. Finally, conclusions on the work realized are
provided in Chapter 4.; La fotónica de silicio es una de las tecnologías fotónicas que está experimentando un
crecimiento más excitante y rápido en los últimos años. La característica más destacada
de esta tecnología es su compatibilidad con las maduras técnicas de fabricación de
circuitos integrados de silicio basadas en los procesos ¿complementary metal-oxide
semiconductor¿ (CMOS) ampliamente utilizados en la industria microelectrónica. Otra
motivación es la disponibilidad de circuitos de guía de ondas planas de silicio sobre
aislante (SOI) de alta calidad que ofrecen un fuerte confinamiento óptico debido al alto
contraste índices entre el silicio (n=3,45) y el SiO2 (n = 1,45). Esto abre las puertas a la

▼ In this PhD Thesis I present some methods for characterizing PA-LCoS microdisplays. It is useful to fully characterize this type of devices for evaluating its performance required in different applications. We have tested its validity in different applications such as diffractive optics elements (DOEs). Finally we apply these microdisplays in a full holographic data storage scheme using a photopolymer as holographic recording medium. We evaluate the capability of PVA/AA photopolymer for this holographic data storage system that incorporates as a novelty a convergent correlator geometry.

▼ An electro-optic resonant modulator consists of a
dielectric material that responds to an applied electric field by
way of amplitude modulation, as an
optical signal propagates
through and resonates within. This work focuses on the analysis and
fabrication of the resonator. The resonator is of a Fabry-Perot
type, employing a titanium indiffused lithium niobate waveguide as
the
optical guide. The resonator is an integrated device and able
to be fiber pigtailed, to be used as a remote device. A z-cut
lithium niobate resonator with dielectric mirror coatings was
fabricated with a finesse of 14, for the TM-like mode at an
operating wavelength of 1.55 micrometers. The cleavage planes of
lithium niobate are investigated and incorporated in the final
design of the resonator. The cleaved edges eliminate the need for
the edge polishing that is used for the mirrors of the Fabry-Perot
resonant cavity. The desired cleaved edges require the use of a
x-cut lithium niobate substrate, with differing orientations of the
titanium indiffused waveguide for the ordinary and extraordinary
modes. This dissertation presents a theoretical analysis of the
electromagnetic wave in a medium with off-diagonal components in
the permittivity tensor, as is necessary for the cleaved edge
resonator geometry. A theoretical analysis of the electro-optic
effect for the cleaved edge geometry is also presented. A cleaved
edge titanium indiffused lithium niobate resonator was fabricated,
and resonances were observed at 13.5 GHz and 14.3 GHz for the
ordinary and extraordinary modes, respectively with 2 nm gold
coated facets, at an operating wavelength of 1.3 micrometers. Given
the useable cleavage planes of z-cut lithium niobate, an
equilateral triangle resonator is proposed. The theoretical and
experimental results contained in this dissertation validate the
feasibility and viability of a Fabry-Perot resonator as a
modulating medium.

▼ Inter-chip input-output (I/O) communication bandwidth demand, which rapidly scaled with integrated circuit scaling, has leveraged equalization techniques to operate reliably on band-limited channels at additional power and area complexity. High-bandwidth inter-chip
optical interconnect architectures have the potential to address this increasing I/O bandwidth. Considering future tera-scale systems, power dissipation of the high-speed I/O link becomes a significant concern. This work presents a design flow for the power optimization and comparison of high-speed electrical and
optical links at a given data rate and channel type in 90 nm and 45 nm CMOS technologies.
The electrical I/O design framework combines statistical link analysis techniques, which are used to determine the link margins at a given bit-error rate (BER), with circuit power estimates based on normalized transistor parameters extracted with a constant current density methodology to predict the power-optimum equalization architecture, circuit style, and transmit swing at a given data rate and process node for three different channels. The transmitter output swing is scaled to operate the link at optimal power efficiency. Under consideration for
optical links are a near-term architecture consisting of discrete vertical-cavity surface-emitting lasers (VCSEL) with p-i-n photodetectors (PD) and three long-term integrated photonic architectures that use waveguide metal-semiconductor-metal (MSM) photodetectors and either electro-absorption modulator (EAM), ring resonator modulator (RRM), or Mach-Zehnder modulator (MZM) sources. The normalized transistor parameters are applied to jointly optimize the transmitter and receiver circuitry to minimize total
optical link power dissipation for a specified data rate and process technology at a given BER.
Analysis results shows that low loss channel characteristics and minimal circuit complexity, together with scaling of transmitter output swing, allows electrical links to achieve excellent power efficiency at high data rates. While the high-loss channel is primarily limited by severe frequency dependent losses to 12 Gb/s, the critical timing path of the first tap of the decision feedback equalizer (DFE) limits the operation of low-loss channels above 20 Gb/s. Among the
optical links, the VCSEL-based link is limited by its bandwidth and maximum power levels to a data rate of 24 Gb/s whereas EAM and RRM are both attractive integrated photonic technologies capable of scaling data rates past 30 Gb/s achieving excellent power efficiency in the 45 nm node and are primarily limited by coupling and device insertion losses. While MZM offers robust operation due to its wide
optical bandwidth, significant improvements in power efficiency must be achieved to become applicable for high density applications.

▼ This thesis deals with
optical synthesis of unmodulated and modulated microwave signals. Generation of microwave signals based on
optical heterodyning is discussed in detail.
The effect of phase noise of laser on heterodyned output has been studied for different phase noise profiles. Towards this, we propose a generic algorithm to numerically model the linewidth broadening of a laser due to phase noise. Generation of microwave signals is demonstrated practically by conducting an
optical heterodyning experiment. Signals ranging in frequency from 12.5 MHz to 27 GHz have been generated.
Limitations of
optical heterodyning based approach in terms of phase noise performance and frequency stability are discussed and practically demonstrated. A hardware-efficient
Optical Phase Locked Loop (OPLL) is proposed to overcome these issues. Phase noise tracking performance of the proposed OPLL has been experimentally demonstrated. Phase noise values as low as -105 dBc/Hz at 10 KHz offset have been achieved.
Optical modulators, owing to their extremely low electro-optic response time, can support high frequency modulating signals. This makes them highly attractive in comparison to their microwave counterparts. In this thesis, we propose techniques to generate microwave signals modulated at very high bit rates by down-converting the corresponding modulated
optical signals to microwave domain. Down-conversion required for this process is achieved by
optical heterodyning. The proposed concept has been theoretically analyzed, simulated and experimentally validated. Amplitude Modulated and ASK modulated microwave signals have been generated as Proof-of-Concept.
Limitations posed by OPLL in generation of angle modulated microwave signals by
optical heterodyning have been brought out. Schemes overcoming these limitations have been proposed towards generation of BPSK and QPSK modulated microwave signals.
Integrated Optics (IO) technology has been studied as a means of implementation of the proposed concepts. IO components like Sinusoidal bends, Y-branch splitters and Electro-Optic-
Modulators (EOMs) have been designed towards
optical synthesis of modulated microwave signals. Propagation of modulated
optical signal through these IO components has also been studied.
An all-optic scheme based on
Optical Beam Forming is proposed for transmission of QPSK modulated signal. Limitation of phase-shifting based approach, in terms of beam-squint, has been brought out. True-Time-Delay based approach has been proposed for applications demanding wide instantaneous bandwidth to avoid beam-squint.
Algorithms / numerical methods required for analyses and simulations associated with the above-mentioned tasks have been evolved.
This study is envisaged to provide useful insight into the realization of high-speed, compact, light-weight data transmitting systems based on Integrated Optics for future onboard spacecraft applications. This work, we believe, is a step towards realization of an Integrated Optic System-on-Chip solution for specific microwave…

▼ The increasing integration of digital information with our daily lives has led to the rise of big data, cloud computing, and the internet of things. The growth in these categories will lead to an exponential increase in the required capacity for data centers and high performance computation. Meanwhile, due to bottlenecks in data access caused by the limited energy and bandwidth scalability of electrical interconnects, computational speedup can no longer scale with demand. A better solution is necessary in order to increase computational performance and reduce the carbon footprint of our digital future.
People have long thought of photonic interconnects, which can offer higher bandwidth, greater energy efficiency, and orders-of-magnitude distance scalability compared to electrical interconnects, as a solution to the data access bottleneck in chip, board, and datacenter scale networks. Over the past three decades we have seen impressive growth of photonic technology from theoretical predictions to high-performance commercially available devices. However, the dream of an all-optical interconnection network for use in CPU, Memory, and rack-to-rack datacenter interconnects is not yet realized. Many challenges and obstacles still have to be addressed. This work investigates these challenges and describe some of the ways to overcome them.
First we will first examine the pattern sensitivity of microring modulators, which are likely to be found as the first element in an optical interconnect. My work will illustrate the advantage of using depletion mode modulators compared to injection mode modulators as the number of consecutive symbols in the data pattern increases.
Next we will look at the problem of thermal initialization for microring demultiplexers near the output of the optical interconnect. My work demonstrates the fastest achieved initialization speed to-date for a microring based demultiplexer. I will also explore an thermal initialization and control method for microrings based on temperature measurement using a pn-junction.
Finally, we will look at how to control and initialize microring and MZI based optical switch fabrics, which is the second element found in a optical interconnect. Work here will show the possibility of switching high-speed WDM datastreams through microring based switches, as well as methods to deal with the complexities inherent in control and initialization of high-radix switch topologies.
Through these demonstrations I hope to show that the challenges facing optical interconnects, although very real, are surmountable using reasonable engineering efforts.

▼ Optical communication is a high speed, large bandwidth, low cost, and power efficient method of transferring data over short-haul and long-haul channels.
Optical communication requires devices (
optical modulators) that utilize the originating electrical signal information to modulate a corresponding
optical signal. State of the art
optical modulators can be used for communicating signals at modulation frequencies up to 100 GHz and faster. Polymer
modulators are used over lithium niobate due to the large potential electro-optic coefficient, which has been shown to be as high as 226 pm/V in thin films.
Organic electro-optic polymers used in thin film
modulators contain nonlinear
optical chromophore dipoles that when aligned produce an electro-optic coefficient from the pockels effect. The magnitude of the electro-optic coefficient is dependent on the strength and uniformity of the electric field applied to the thin film polymer. In multi-layer devices the applied field is determined by design, fabrication, layer thickness, and pinhole defects that cause dielectric breakdown of the device. A laboratory process was designed and created for electro-optic contact poling of waveguide devices and thin film polymers. A sample is heated to the glass transition temperature of the electro-optic polymer and an electric field is applied to allow alignment of chromophores. The sample is then cooled to room temperature to lock the chromophores in place. Soluxra SEO100C polymer is used for validation of the poling process because of its high electro-optic coefficient potential.
First time large area contact poling of electro-optic polymer thin films is performed and verified enabling the use of electro-optic polymers in a variety of applications. The index of refraction change after poling was measured in Soluxra SEO100C spun thin films using a prism coupler to verify poling. TM index of refraction of thin film SEO100C increased by 0.00402-0.00486 with voltages of 39-51 V/μm after poling. SEO100C thin films were exposed to processing steps used during fabrication of devices for proof of concept for electro-optic poling mid-process in reduce applied voltage. The TM indexes relaxed an average of 16% back to their original values when exposed to the extra processing. A laboratory was built for electro-optic coefficient and performance calculation in multi-layer devices for future verification of poling. The half-wave voltage (V
π) and intermodulation distortion (IMD) was shown as a proof-of-concept on a commercial Mach-Zehnder modulator.

▼ The accelerating increase in information traffic demands the expansion of
optical access network systems that require high-performance
optical and photonic components. In short-range communication links,
optical interconnects have been widely accepted as a viable approach to solve the problems that copper based electrical interconnects have encountered in keeping up with the surge in the data rate demand over the last decades. Low cost, ease of fabrication, and integration capabilities of low
optical-loss polymers make them attractive for integrated photonic applications to support futuristic data communication networks. In addition to passive wave-guiding components, electro-optic (EO) polymers consisting of a polymeric matrix doped with organic nonlinear chromophores have enabled wide-RF-bandwidth and low-power active photonic devices. Beside board level passive and active
optical components, on-chip micro- or nano-photonic devices have been made possible by the hybrid integration of EO polymers onto the silicon platform. In recent years, silicon photonics have attracted a significant amount of attentions, because it offers compact device size and the potential of complementary metal–oxide–semiconductor (CMOS) compatible photonic integrated circuits. The combination of silicon photonics and EO polymers can enable miniaturized and high-performance hybrid integrated photonic devices, such as electro-optic
modulators,
optical interconnects, and microwave photonic sensors. Silicon photonic crystal waveguides (PCWs) exhibit slow-light effects which are beneficial for device miniaturization. Especially, EO polymer filled silicon slotted PCWs further reduce the device size and enhance the device performance by combining the best of these two systems. The potential applications of these silicon-polymer hybrid integrated devices include not only
optical interconnects, but also
optical sensing and microwave photonics. In this dissertation, the design, fabrication, and characterization of several types of silicon-polymer hybrid photonic devices will be presented, including EO polymer filled silicon PCW
modulators for on-chip
optical interconnects, antenna-coupled
optical modulators for electromagnetic wave detections, and low-loss strip-to-slot PCW mode converters. In addition, some polymer-based devices and silicon-based photonic devices will also be presented, such as traveling wave electro-optic polymer
modulators based on domain-inversion directional couplers, and silicon thermo-optic switches based on coupled photonic crystal microcavities. Furthermore, some microwave (or RF) components such as integrated broadband bowtie antennas for microwave photonic applications will be covered. Some on-going work or suggested future work will also be introduced, including in-device pyroelectric poling for EO polymer filled silicon slot PCWs, millimeter- or Terahertz-wave sensors based on EO polymer filled plasmonic slot waveguide, low-loss silicon-polymer hybrid slot photonic crystal waveguides fabricated by CMOS foundry, logic…

▼ Traffic from wireless and mobile devices is predicted to increase 10-fold between 2014 and 2019, surpassing wired data traffic by 2016. Given the expected radio frequency (RF) capacity crunch, this growing wireless demand will have to be met using a variety of new technologies exploiting other parts of the electromagnetic spectrum. Promising research areas include the Millimetre Band as well as Optical Wireless Communications (OWC). Millimetre Band demonstrations have accomplished ultrafast multi-Gigabit links, making use of state-of-the-art fibre transmission systems. However, complex opto-electronic (OE) interfaces are required to convert the optical carrier into Millimetre wireless signals. To avoid these interfaces, an all-optical transparent network is proposed here, spanning over both the fibre and OWC domains, in order to deliver ultrahigh data rates to mobile end-users in indoor environments. This is supported by the recent deployment of fibre-to-the-home (FTTH) networks creating the potential for Terabit aggregate connections at the user's doorstep. Therefore, infrared fibre-wireless-fibre (FWF) links are studied to support data rates over 100 Gb/s in nomadic applications. The link coverage is achieved via narrow beam beamsteering over a wide field-of-view (FOV) using suitable localization and tracking techniques. The proposed model is inherently bidirectional and transparent, i.e. independent of the data rate and modulation format. In this thesis, the potential for ultrafast wide coverage OWCs using SMF-based transceivers and coherent transmission is demonstrated. A record data rate of 418 Gb/s and 209 Gb/s with a wide FOV of θFOV=±30° and θFOV=±20°, respectively, is shown at a free space range of 3 m. To the best of our knowledge, this is the fastest demonstration of an indoor wireless link that offers practical room-scale coverage. The automated alignment of this FWF link is also demonstrated with the design and implementation a mm-accurate localization and tracking system. Finally, architectures for point-to-multipoint communications are explored in order to adapt the system to multiple users.

▼ Optical computing has proven useful in several specialized applications. However, the general development of optical computing is limited by the computational inaccuracies typically found in optical information processing. One source of these inaccuracies is the noise generation and transformation properties of optical devices. The signal and noise models of optical devices are inadequate for information processing system development and optimization. This is specifically true for spatial light modulators. Progress in optical computing requires more accurate models of these optical devices and their signal and noise characteristics.
System modeling of optical devices is complicated by the multiple-port and nonlinear nature of those devices. In this dissertation, the Volterra series model is shown to adequately represent a multiple-port, mildly nonlinear device and is adapted to represent a spatial light modulator. Furthermore, a method is described to experimentally measure the Volterra series model characteristics directly. We develop a three-input, single-output, second-order Volterra series model for a spatial light modulator and describe an experimental method to measure the nonlinear transfer functions using sinusoidal perturbation and synchronous detection with a lock-in amplifier. We review the spectral noise transformation properties of Volterra systems and adapt these results to the multiple-input case. The spectral noise transformation characteristics of optical devices are shown to be calculated directly from the Volterra system model using the nonlinear transfer functions.
These techniques are applied to experimentally measure the Volterra series model characteristics of a Hughes 4050 liquid crystal light valve and estimate closed-form expressions for the nonlinear transfer functions. The validity of the model characteristics and spectral noise transformation is demonstrated by comparing predicted spectral noise characteristics with measured device performance.

▼ En premier lieu, des couches minces épitaxiales ont été obtenues sur des substrats de silicium grâce à l’utilisation de l’épitaxie par jets moléculaire et de couches tampons de titanate de strontium SrTiO3. Une technique de croissance par co-déposition a été développée de manière à obtenir un rapport Ba:Ti proche de la stoechiométrie, et ce afin d’éviter la formation de défauts cristallins dans la couche de BaTiO3. Le matériau déposé cristallise dans une structure de symétrie quadratique, ce qui est unpré-requis pour l’obtention de propriétés électro-optiques. De plus, selon les conditions de croissance, l’axe c de la maille élémentaire quadratique a pu être ajusté de manière à être aligné parallèlement ou perpendiculairement à la surface du substrat. L’utilisation d’une mince couche tampon de nucléation a également permis de croitre des films mincesBaTiO3 épitaxiées par pulvérisation, technique largement répandue en milieu industriel.Un coefficient de Pockels élevé a par la suite été obtenu sur de tellescouches épitaxiées. La valeur mesurée de 148pmV est clairement supérieure aux valeurs admises dans la littérature pour d’autres matériaux nonlinéairestels que le niobate de lithium, pour lequel un coefficient de31pmV est rapporté. La méthode de caractérisation électro-optique développée à cette occasion révèle également le caractère ferroélectrique des couches de BaTiO3, observé pour la première fois dans de tels matériaux épitaxiés sur silicium.Finalement, ces couches minces électro-optiquement actives ont été intégrées dans des dispositifs photoniques sur silicium. Dans cette optique,une structure de guide d’onde à fente a été utilisée en insérant 50nm deBaTiO3 entre deux couches de silicium. Dans ce type de structure, le confine mentoptique est 5 fois supérieur à celui obtenu pour des guides d’onde en silicium avec une gaine à base de BaTiO3. Des guides d’ondes rectilignesont tout d’abord été fabriqués, pour lesquels des pertes optiques del’ordre de 50−100 dB/cm ont été mesurées. Par la suite, des composants passifs fonctionnels ont été fabriqués, tels que des interféromètres typeMach-Zehnder, des résonateurs circulaires et des coupleurs. Finalement,la fonctionnalité de composants actifs a été démontrée pour la première fois, en se basant notamment sur des résonateurs ayant un facteur de qualité Q d’environ 5000, et pour lequel la résonance varie en fonction du champ électrique transverse. L’origine physique de cette variation n’a cependant pas pu être expliquée sur la seule base de l’effet Pockels. Cette thèse démontre que l’utilisation de nouveaux matériaux électro optiquement actifs au coeur de dispositifs photoniques sur silicium créede nouvelles opportunités pour la conception et l’ingénierie de circuitsphotoniques. L’intégration d’oxydes tels que barium titanate permet d’envisager de nouveaux concepts de dispositifs pour ajuster, moduler ou commuter la lumière au sein de circuits photoniques denses. De nouveaux défis et perspectives s’ouvrent également aux scientifiques pour modifier artificiellement les…

▼ Barium titanate thin films were deposited onto silica-clad silicon using a sol-gel spin coating process. Such films could have valuable applications as electro-optic waveguide components and devices. A large polymer, polyvinylpyrrolidone, was added to a conventional acetate-based sol-gel to increase film thickness. The effect of processing parameters on thin film properties was studied using several techniques including prism coupling. This method also was used to study the optical loss in the films. The films were heat-treated under various conditions and a rapid heating recipe (fast ramp to 500ºC then 700ºC for 30 minutes) was shown to fully crystallize the film to perovskite BaTiO3. The as deposited films show desirably low loss (~1 dB/cm). However, the loss in all the fired films was very high despite the fact that the grain size in the film is on the order of 10-20nm. The results indicated that this high loss was locked into the system early during the organic removal phase, which was unexpected. Pyrolysis of the large polymeric molecules can be expected to create a new structure within the porous film consisting of isolated, but interconnected nanodomains of solid. A mechanism is proposed where clusters of the domains scatter light in the pyrolyzed films. This phenomenon evidently continues to dominate all the way to the final densified polycrystalline state.

▼ As high bandwidth applications continue to emerge, investigation in technologies that

Time Division Multiplexing (OTDM) has been presented as a possible solution, supporting
a next generation bit rate of 160 Gbit/s. To perform the demultiplexing task,
the use of tandem electro-absorption modulators (EAMs) has been widely studied,
and due to its benefits was chosen as the topology of this thesis.
To create an effective model of an OTDM system, the vector based mathematical
simulation tool MatLab is used. Care was taken to create an accurate representation
of an OTDM system, including: the development of a realistic pulse shape, the
development of a true pseudo-random bit sequence in all transmitted channels, the
optimization of the gating function, and the representation of system penalty.
While posing impressive bit rates, various sources of system performance degradation
pose issues in an OTDM system, owning to its ultra-narrow pulse widths.
The presence of dispersion, timing jitter, polarization mode dispersion, and nonlinear
effects, can sufficiently degrade the quality of the received data. This thesis gives a clear guideline to the tolerance an OTDM system exhibits to each of the aforementioned sources of system penalty. The theory behind each impairment is thoroughly discussed and simulated using MatLab. From the simulated results, a finite degree of sensitivity to each source of system penalty is realized. These contributions are of particular importance when attempting to implement an OTDM system in either the laboratory, or the field.

▼ With the progress of microfabrication and nanofabrication technologies, there has been a reawakened interest in the possibility of controlling the propagation of light in various materials periodically structured at a scale comparable to, or slightly smaller than the wavelength. We can now engineer materials with periodic structures to implement a great variety of
optical phenomena. These include well known effects, such as dispersing a variety of wavelength to form a spectrum and diffracting light and controlling its propagation directions, to new ones such as prohibiting the propagation of light in certain directions at certain wavelengths and localizing light with defects in some artificially synthesized dielectric materials. Advances in this field have had tremendous impact on modern
optical and photonic technologies. This doctoral research was aimed at investigating some of the physics and applications of periodic structures for building blocks of the
optical communication and interconnection system. Particular research emphasis was placed on the exploitation of innovative periodic structure-based
optical and photonic devices featuring better functionality, higher performance, more compact size, and easier fabrication. Research topics extended from one-dimensional periodic-structure-based true-time delay module, to two-dimensional periodic-structure-based silicon photonic-crystal electro-optic
modulators. This research was specifically targeted to seek novel and effective solutions to some long-standing technical problems, such as slow switching speed, large device size, and high power consumption of silicon
optical modulators, among others. For each subtopic, research challenges were presented and followed by the proposed solutions with extensive theoretical analysis. The proposals were then verified by experimental implementations. Experimental results were carefully interpreted and the future improvements were also discussed.

▼ Holographic optical trapping (HOT) is a technique for non-invasive dynamic anipulation of multiple microscopic objects, which has been used for many applications in the life sciences during the past decade. The technique uses holographic beam steering with a spatial light modulator (SLM) to direct light to the desired positions of optical traps. In many cases, the control of the optical intensity of the traps is impaired by imperfections in the SLM. This has limited the use of HOT for applications sensitive to variations in the trap intensities, such as optical force measurement (OFM). Also, the algorithms for optimization of holograms used in HOT are computationally demanding, and real-time manipulation with optimized holograms has not been possible. In this thesis, four different methods for improving the accuracy of holographic beam steering are presented, along with a novel application for the combination of HOT and position measurement. The control of trap intensities is improved by compensating for crosstalk between pixels, and for spatial variations of the phase response of the SLM; and by dumping a controlled amount of light to specified regions away from the traps. Variations in trap intensities occurring when updating the SLM with new holograms are suppressed by enforcing a stronger correlation between consecutive holograms. The methods consist of modifications of the algorithm used for hologram generation, or alternative methods for post-processing of generated holograms. Applications with high stability requirements, such as OFM with HOT, will benefit from the presented improvements. A method for reducing computation time for hologram optimization is also presented, allowing the accuracy improvements to be used also for time critical applications. Further, it is shown that position measurement of nanowires, held by multiple optical traps, can be used to probe the orientational structure and defects in liquid crystal materials.

▼ A hybrid silicon and lithium noibate
(LiNbO
3) material system is developed to
combine the high index contrast of silicon and the second order
susceptibility of lithium niobate. Ion-sliced single crystalline
LiNbO
3 thin film is bonded to
silicon-on-insulator (SOI) waveguides via Benzocyclobutene (BCB) as
the top cladding. The LiNbO
3 thin films are
patterned to achieve desired size, shape and crystal orientations.
Integrated electrodes are integrated to confine electric fields to
the LiNbO

integrated photonic devices are enabled on the SOI platform,
including radio-frequency electric field sensors, tunable
optical
filters, high speed electro-
optical modulators for
optical
interconnects, and high linearity
modulators for analog

indirect bonding of z-cut ion-sliced LiNbO

sensitivity to electric fields is 4.5 V

optical filters based on hybrid
Si/LiNbO
3 microring resonators with
integrated electrodes are also demonstrated with a tunability of
12.5 pm/V, which is over an order of magnitude greater than
electrode-free designs. By integrating metal thin film electrode
and utilizing silicon as an optically transparent electrode,
voltage induced electric fields in the
LiNbO
3 are enhanced. We also presented low
power compensation of thermal drift of resonance wavelengths in
hybrid Si/LiNbO
3 ring resonators. A
capacitive geometry and low thermal sensitivity result in the
compensation of 17
oC of temperature
variation using tuning powers at sub-nanowatt levels. The method
establishes a route for stabilizing high quality factor resonators
in chip-scale integrated photonics
subject to temperature
variations. Gigahertz speed hybrid Si/LiNbO
3
electro-
optical microring
modulators are enabled by optimizing the
RC time constant of the biasing electrodes. Fabricated devices
exhibit a resonance tuning of 3.3 pm/V and a small-signal
electrical-to-
optical 3 dB bandwidth of 5 GHz. Digital modulation
with an extinction ratio greater than 3 dB is demonstrated up to 9
Gb/s. High-speed and low tuning power chip-scale
modulators that
exploit the high-index contrast of silicon with the second order
susceptibility of lithium niobate are envisioned. An alternative
design with x-cut LiNbO

▼ Silicon photonics provides a promising platform for developing densely integrated, highly scalable and potentially very low cost solutions for various applications in the field of
optical data communications. This thesis focuses on the technical challenges in silicon photonics on both the component and system levels. One of the most important components in
optical transmitters is the electro-optic modulator. However, building high-speed efficient
modulators in silicon remains to be one of the key challenges of silicon photonics. To achieve more efficient
modulators, the first approach presented here is to incorporate new materials into the silicon platform with new device geometries. With highly efficient electro-
optical polymers and low-loss silicon striploaded slot waveguide, we demonstrated the first silicon-polymer hybrid modulator operating with GHz bandwidth as well as the first sub-1 Vπ device at RF frequency. The second approach is innovative RF design, through which we demonstrated 40 Gb/s power-efficient silicon pn-junction traveling-wave Mach-Zehnder
modulators showing compelling performance compared to commercial Lithium Niobate
modulators. At the time of writing, system level designs in silicon photonics are far from mature. A critical barrier toward system design is the lack of established stable fabrication processes and process design kits (PDKs). I participated in and lead the testing effort of the early development of an monolithic silicon photonics platform (OpSIS-IME). High-speed (50 Gb/s)
modulators and detectors as well as high-performance passive components co-exist in the same process with consistent performance and high yield. This opens up tremendous opportunities for systems. Upon this platform, we demonstrated various kinds of high-speed high-performance transmitters and receivers using different topologies and device approaches, showing a level of integration beyond the state-of-the-art. For a power-efficient and high-performance photonics system, electronics and in particular the high-speed analog front-end that directly interfaces with the photonic devices is an integral part and to a great extent determines system-level performance. Furthermore, close-integration and co-design offer potentially significant improvement to the overall system performance. Among several other high-speed analog circuits results, we have demonstrated on both the
optical transmitter and the receiver sides, that ultra-high data rate (100 Gb/s non-return-to-zero) is plausible in existing silicon-based photonics and electronics technology.

▼ The development of integrated photonics is limited by bulky and inefficient photonic component compared to their electronic counterparts due to weak light-matter interactions. As the key devices that determine the performance of integrated photonic circuits, electro-
optical (EO)
modulators are inherently built on the basis of enhancing light-matter interactions. Current EO
modulators often deploy conventional materials with poor EO properties, or ring resonator structure with narrow bandwidth and thermal instability, so their dimensions and performance have nearly reached their physical limits. Future integrated photonic interconnects require EO
modulators to be ultra-compact, ultra-fast, cost-effective and able to work over a broad bandwidth. The key to achieving this goal is to identify an efficient and low-cost active material. Meanwhile, novel waveguides and platforms need to be explored to significantly enhance light-active medium interaction. As widely investigated novel materials, graphene and conductive oxide (COx) have shown remarkable EO properties. The objective of this dissertation is to realize enhanced light-matter interaction based on these two novel materials and waveguiding platforms, and further develop ultra-compact, ultra-fast EO
modulators for future photonic integrated circuits. The first part of this dissertation covers the theory of EO modulation mechanisms, several types of EO materials including graphene and COx, as well as fabrication techniques. The second part demonstrates greatly enhanced light absorption based on mono-/multi-layer graphene. The third part proposes the theoretical study of nanoscale EA
modulators based on ENZ-slot waveguide. The fourth part explores the field effect within a MOS-like structure, and verifies the ENZ behavior of COx. The fifth part experimentally demonstrates both plasmonic and dielectric configurations for ultra-compact and ultra-fast EA
modulators. The final part summarizes the work presented in this dissertation and also discusses some future work for photonic applications.

▼ In this thesis, studies on the applications of digital micro-mirror devices (DMD) to enhancement of digital
optical microscope images are presented. This involves adaptation of the fast switching capability and high
optical efficiency of DMD to control the spatial illumination of the specimen.
The first study focuses on a method of using DMD to enhance the dynamic range of a digital
optical microscope. Our adaptive feedback illumination control method generates a high dynamic range image through an algorithm that combines the DMD-to-camera pixel geometrical mapping and a feedback operation. The feedback process automatically generates an illumination pattern in an iterative fashion that spatially modulates the DMD array elements on a pixel-by-pixel level. Via experiment, we demonstrate a transmitted-light microscope system that uses precise DMD control of a DMD-based projector to enhance the dynamic range ideally by a factor of 573. Results are presented showing approximately 5 times the camera dynamic range, enabling visualization over a wide range of specimen characteristics.
The second study presents a technique for programming the source of the spherical reference illumination in a digital in-line holographic microscope using DMD. The programmable point source is achieved by individually addressing the elements of a DMD to spatially control the illumination of the object located at some distance from the source of the spherical reference field. Translation of the ON-state DMD mirror element changes the spatial location of the point source and consequently generates a sequence of translated holograms of the object. The experimental results obtained through numerical reconstruction of translated holograms of Latex microspheres shows the possibility of expanding the field of view by about 263% and also extracting depth information between features in an object volume.
The common challenges associated with the use of DMD in coherent and broadband illumination control in both studies are discussed.
