Dans cette thèse, nous avons étudié la dynamique d'aimantation selon deux échelles de temps en utilisant la technique pompe-sonde magnéto-optique résolue en temps. A l'échelle de la picoseconde, la précession de l'aimantation est induite par des impulsions acoustiques dans des structures multicouches composées de deux couches ferromagnétique séparées par une couche métallique (Ni/Au/Py) avec différentes épaisseurs. La synchronisation de la précession des couches ferromagnétiques couplées a été observée. La modification de la précession de l'aimantation d'une couche de Ni est due l'interaction d'échange intercouche avec la couche Py. A l'échelle de 50fs, nous avons étudié la dynamique magnéto-optique cohérente, athermale, thermale et la relaxation des charges et des spins dans (Ni, Co et Fe) par impulsions de 11 fs dans un régime de faible perturbation. L'interaction spin-orbite et l'interaction d'échange jouent un rôle significatif dans la désaimantation ultrarapide.

In this thesis, we have investigated the magnetization dynamics at picosecond and femtosecond time scale using time resolved magneto-optical pump probe technique. At picosecond time scale, the magnetization precession is induced by ultrafast acoustic pulses in a three layered structure with two ferromagnetic layers separated by varying thickness of metallic spacer layer (Ni/Au/Py). The magnetization precession dynamics of the Ni layer is modified due to the interlayer exchange interaction with the Py layer and the synchronized precession of the coupied ferromagnetic layers has been observed. At the timescale of 50fs, coherent magneto-optical, non-thermal, thermal and relaxation dynamics of charges and spins in ferromagnetic transition metals (Ni, Co and Fe) is studied by using 11fs optical pulses in a very low perturbation regime. The spin orbit interaction and exchange interaction play a significant role in the demagnetization of the ferromagnetic metals induced by femtosecond pulses.

Un des objectifs du Femtomagnetisme est de contrôler l’aimantation des matériaux avec des impulsions laser femtoseconde. Il a été démontré qu’une réponse magnéto-optique (MO) cohérente a lieu avant la thermalisation des populations de spins dans une configuration pompe-sonde MOKE. Elle résulte du couplage cohérent spin-photon dû à l’interaction spin-orbite. Une description simplifiée de cet effet a été faite en tenant compte d’un système à huit niveaux couplés au champ laser. La cohérence MO est définie par le temps de déphasage dépendent du champ T2MO. Dans ce travail, il est montré que la réponse MO cohérente d’un grenat dopé au bismuth peut être mesurée directement avec différentes configurations de mélange à quatre ondes MO. L’importance de connaître la phase spectrale de l’impulsion pour obtenir T2MO a été étudié. Avec des impulsions de 10fs dans le proche infra-rouge, une mesure de T2MO donne (2.8+/-1)fs, c. à d., du même ordre de grandeur que le temps de déphasage des charges.

One of the goals of Femtomagnetism is to manipulate the magnetization of materials using femtosecond optical pulses. It has been shown in ferromagnetic films that a magneto-optical (MO) coherent response takes place before the thermalization of the spins populations in a pump and probe MOKE experiment. It results from the coherent spin-photon coupling mediated by the spin-orbit interaction. A simplified description of this effect has been made by considering an eight-level system coupled with the laser field. The MO coherence can be defined by the magnetic field dependent dephasing time T2MO. In the present work, it is shown that the coherent MO response of a bismuth-doped garnet can be directly measured in different degenerated MO four-wave mixing configurations. The importance of well-knowing the spectral phase of the pulse to measure T2MO was studied. Using 10fs near infra-red pulses, T2MO was shown to be (2.8+/-1)fs that is of the same order of the charges dephasing time.

▼ This thesis is comprised of three major parts and is concerned with the theoretical characterization of condensed phase systems within the framework of nonlinear spectroscopy experiments, using both analytical models and numerical approximation schemes. The first part focuses on the chirped-pulse mediated coherent control of electronic population transfer, and investigates the plausibility of control in the presence of pure electronic dephasing. The molecular system is described by a same-frequency shifted harmonic oscillator model, and population transfer was computed using split-operator and direct diagonalization schemes. Dephasing effects were incorporated using a stochastic model that is able to interpolate between the homogeneous and inhomogeneous limits, and results with and without dephasing were compared as functions of the linear chirp parameter and the field intensity. The numerical findings were compared to and found to be consistent with several experimental studies performed on the laser dye LD690 in liquid methanol. The second part is a comparative study of several approximation methods used for computing optical response functions, and is illustrated within the context of two-dimensional electronic spectroscopy. A central theme is the development of a benchmark model that can discriminate between different methods, and consists of a different-frequency shifted harmonic oscillator model. Optical response spectra were computed using four different approximation schemes, which include two distinctly different second-order cumulant approximations, a Linearized Semiclassical method, and a Forward-Backward Semiclassical method. Comparing the spectra as a function of temperature and the oscillator frequency ratio assessed the accuracy and robustness of the methods. The final part concerned a method for computing ab initio optical response tensors in the context of two-dimensional infrared spectroscopy, and was a collaborative effort between the Geva and Kubarych groups. An excitonic Hamiltonian was used to model the photo-active modes of a vibrational system, and a direct diagonalization procedure, which utilized inputs from electronic structure calculations, was used to compute the spectra. Preliminary results for the four-mode system Mn(CO)5 are presented, and the methodology developed here was later continued and extended by other members of the collaboration.

▼ Bandwidth requirements double up every three years. The main amount of this traffic is carried out by optical networks which form the backbone of communication systems. Accordingly, optical fiber has been designated as the ideal telecommunication channel allowing to achieve rates of tens of Terabits per second transmitted over thousands of kilometers. Such enormous data rates are mandated in order to meet the exponentially increasing data traffic. Unfortunately, by stressing the current technology to its limits, we have found that the experimental achieved capacity has reached a plateau of 100 Tb/s for a single fiber. To overcome this “capacity crunch”, novel optical transmission technologies have to be introduced such as new modulation formats, new transmission fibers and new multiplexing technologies at the coming years. In this thesis we study the coherent optical systems and in particular we derive closed-form expressions which calculate the power of the dominant nonlinear effect which is Four Wave Mixing (FWM). Assuming that the signal approaches Gaussian distribution when FWM dominates, we can simply add the calculated FWM crosstalk along with ASE noise in a performance metric similar to OSNR and readily calculate BER. This approach eases performance estimation ensuring very good accuracy over a wide range of critical system parameters. Moreover, the derived expressions can be used for optimization in terms of BER, transmission length, system capacity, amplifier spacing etc. Depending on the installed modules (i.e. transmitters, receivers, amplifiers etc.) the performance of optical systems can vary greatly and as a consequence performance estimation mandates analytical solutions adapted in each particular case. Accordingly, the proposed simplified expressions of this thesis can model various transmission systems such as systems with and without guard band, uncompensated and dispersion managed systems, fixed-grid and flex-grid systems, homogeneous and heterogeneous systems depending on if identical or non-identical fiber spans are assumed etc. The proposed closed-form expression for the flex-grid case can be considered as a “universal” solution which can be applied in all the aforementioned systems, demonstrating very good accuracy. For the derivation of the proposed expressions we start from the exact FWM model which is approximated for different scenarios. The accuracy of the resulting expressions is verified by comparing them against 1) the exact FWM model and 2) numerical results using a commercial simulation tool, where the fiber is modeled using Split Step Fourier Method (SSFM). The simplified models are extensively tested in a wide range of system parameters and configurations, modeling more practical systems than the existing models of the literature. It is worth mentioning that the most general expression, developed in this thesis, can calculate the performance of any channel or superchannel of the spectrum, accounting for any channel distribution at the spectrum as…

▼ The realization of strong optical magnetism in nominally “non-magnetic” media could lead to novel forms of all-optical switching, energy conversion, or the generation of large (oscillatory) magnetic fields without current-carrying coils. By advancing understanding of radiant optical magnetization, the research reported in this thesis contributes progress toward these prospects. Experiments and simulations were performed of light scattering in natural dielectrics at non-relativistic optical intensities. The goal was to understand which molecular factors influenced the magnitude of induced magnetic dipole scattering in isotropic materials. The intensity dependence and spectra of cross-polarized scattering in several transparent molecular liquids (CCl4, SiCl4, GeCl4, SnCl4, SiBr4, TMOS, TEOS, TPOS) and crystalline solids (GGG, Quartz) were found to agree with predictions of quantum theory. Additionally, evidence was found for the expected proportionality between the intensity of radiant magnetization and the electric dipole transition moment, together with an inverse proportionality with respect to molecular rotation frequency. By comparing spectra in molecular liquids, it was found that spectral features in the cross-polarized scattering were uniquely attributable to high-frequency librations of magneto-electric (M-E) origin. In solids, optically-induced magnetic scattering in solids reached the same intensity as Rayleigh scattering, far below relativistic conditions. Additionally, all four channels predicted by the quantum theory for second-order (2-photon) M-E processes at the molecular level were observed in experiments on GGG crystals. Two theoretical contributions are presented in this thesis. The first is an extension of the classical Lorentz Oscillator Model from an atomic to a molecular picture. It includes the effect of torque exerted by the optical magnetic field on excited state orbital angular momentum, resulting in an enhancement in the magnetization achievable under non-relativistic conditions in molecular or condensed matter systems. Temporal dynamics are predicted for the first time, taking into account molecular composition. Secondly, the torque Hamiltonian of quantum theory is shown to obey Parity-Time (PT) symmetry, indicating that M-E effects should occur universally. Lastly, results from classical and quantum mechanical models are compared and found to be in very satisfactory agreement.

Neste trabalho é apresentada a construção da montagem de um sistema experimental para resfriar átomos de estrôncio. A construção do sistema está focada no estudo do espalhamento coletivo em nuvens atômicas frias e ultrafrias por meio da teoria de Mie. O estrôncio é um elemento que conta com dois estágios de resfriamento, o primeiro utilizando a transição forte entre estados singletos ¹S₀-¹P ₁ de Γ = (2 π)32 MHz, e o segundo com uma transição fraca entre estados singleto e tripleto ¹S₀-³P₁ de Γ = (2 π)7,5 MHz. O objetivo deste trabalho é a construção do sistema para resfriar átomos de estrôncio utilizando a primeira transição. A construção do sistema se apresenta em várias partes, primeiro a construção do um forno como fonte de vapor de estrôncio, onde o estrôncio metálico é aquecido até uma temperatura T = 600°C. O forno conta com um sistema de microtubos encarregados de colimar o feixe atômico, estes microtubos tem um diâmetro interno D ≈ 180µm e um comprimento de 8mm. Depois da implementação do forno e do sistema de microtubos foi medido o perfil de velocidades transversais e a divergência do feixe atômico que sai do forno. A largura tem um valor wr = (2π)108 MHze a divergência do feixe de α ≈4,12. A segunda parte do sistema conta com a construção do desacelerador Zeeman, responsável por desacelerar os átomos do feixe atômico utilizando um feixe laser contrapropagante de λ=461 nm, circularmente polarizado e com uma dessintonização utilizada, após a caracterização do sistema, de Δ=(-2π)580MHz. Os átomos sentiram os efeitos da força de pressão radiativa dentro de um tubo de comprimento de 0,28m. Para compensar o efeito Doppler causado pelo movimento dos átomos foi utilizado um arranjo de bobinas em configuração spin flip para gerar o campo. A terceira e principal parte do sistema foi a construção da armadilha magnetoóptica (AMO). Onde os átomos que saem do desacelerador Zeeman são confinados e resfriados pela combinação de seis feixes contrapropagantes, dos quais três são retrorefletidos utilizando a transição Γ=(2π)32MHz. A dessintonia dos feixes após da caracterização do sistema foi de Δ=(-2π)39MHz. Depois da construção do sistema foi feita a primeira caracterição da armadilha magneto-óptica de átomos de estrôncio 88 em nosso grupo, onde obtivemos a temperatura dos átomos na armadilha para o eixo vertical da expansão foi de Tv=4.7mK e para o eixo horizontal de TH=4mK. Também foi medido o tempo de carga dos átomos na armadilha tcarga=0.15s como bombeamento óptico de estado ³P₂-³D₂. O tempo de vida foi de 0.3s e 0.03s com e sem bombeamento óptico, respectivamente.

Neste trabalho apresentamos a construção e caracterização de uma armadilha magneto-óptica, a qual utilizamos para aprisionamento de átomos de Rb. Após a construção da armadilha e sua caracterização, fizemos experimentos para estudar os efeitos da luz de banda larga sobre os átomos aprisionados. Para esse estudo, utilizamos lâmpadas incandescentes que possuem um espectro largo de comprimentos de onda. Verificamos que em uma armadilha com 109 átomos aprisionados, a luz de banda larga aumenta a fluorescência emitida pela nuvem de átomos, tendo fortes indícios que isto representa efetivamente um aumento na eficiência da armadilha. No entanto, com os experimentos que fizemos, não podemos distinguir se essa diferença é referente a um aumento de átomos aprisionados ou apenas espalhamento de luz causado pelo aumento da intensidade de luz incidida sobre a nuvem. Fizemos então uma comparação da resposta dos átomos, frente a variações na intensidade dos feixes de laser utilizados para o aprisionamento. Por motivos que serão discutidos neste trabalho, refizemos esse estudo com um número menor de átomos aprisionados, 108 átomos, e verificamos que o aquecimento das lâmpadas reflete no aumento das perdas na armadilha, diminuindo então o número de átomos aprisionados. Isto nos levou a fazer um estudo sobre a dinâmica das colisões presentes na armadilha, para entendermos a influência da temperatura na eficiência da armadilha. Verificamos que um pequeno aumento uniforme na temperatura da câmara levaria a grandes perdas na armadilha, mas o aumento da temperatura causado pelas lâmpadas é um aumento local, e gera um processo de desgaseificação da câmara, aumentando a quantidade de átomos, "diferentes de Rb", presentes no vapor de fundo.

In this work we present the building and characterization of a Magneto-Optical Trap (from now on named MOT) for Rubidium atoms. We perform experiments for studying the eect of a broadband light over trapped atoms. In order to carry out this study we used a incandescent lamp which is broad in the wavelength spectrum. We observed in a MOT, with a number of 109 trapped atoms, that the broadband light increases the emitted .uorescence by the cloud of atoms. This could indicate an eective enlargement in the trap eciency. However, we cannot distinguish, based on our experiments, if this dierence is due to an increasing in the number of the trapped atoms or if it is just scattered light caused by the increasing in the intensity of the incident light over the cloud. Thus, we did an analysis in the answer of the laser beam versus the variation in the intensity of lasers used for trapping. In a second step, we perform this study but with a lower number of trapped atoms, 108 atoms, and we verify that the heating of the lamps implies in the increasing of the loss of atoms in the trap, diminishing the number of trapped atoms. Hence, this lead us to make a study on the collisions dynamics that are in the trap, in order to understand the in.uence of the temperature on the trap eciency. We observe that a small uniform…

Neste trabalho apresentamos um estudo sobre as influências que um campo quadripolar magnético, periodicamente dependente do tempo, pode promover em uma armadilha magnético-óptica (Magneto Optical Trap - MOT). O objetivo deste trabalho reflete o interesse em encontrar uma configuração de campo oscilante que possibilite o aprisionamento e forneça vantagens em relação ao processo típico de armadilhamento. Em muitos dos trabalhos que serão citados aqui, um MOT utiliza um campo magnético quadripolar estacionário que promove um gradiente de campo magnético linear à partir do centro da armadilha. Usando resultados experimentais envolvendo oscilações no campo magnético, que serão citados mais detalhadamente no decorrer deste texto, surgiu a iniciativa de modelar o problema matematicamente e buscar uma forma de oscilação que possa resultar em um aprisionamento mais eficiente. Resultados numéricos concebidos em um modelo unidimensional sugerem que o número de átomos é fortemente afetado pelas oscilações, mas não foi possível encontrar, para as modulações sugeridas neste trabalho, uma modulação que pudesse fornecer aumento expressivo no número de átomos armadilhados. Foi possível constatar que a freqüência da oscilação a que o átomo é submetido, afetará a amplitude das oscilações no número de átomos armadilhados.

This work presents a study about infuences that a quadripolar magnetic field periodically time dependent, can promote in a magneto-optical trap (MOT). The intention reflects the interest in finding an oscillating field configuration that enables the capture and provide benefits if compared to the typical process of trapping. In many papers that will be cited here, a MOT uses a magnetic field that promotes a linear steady magnetic field gradient from the center of the trap. Applying experimental results involving magnetic field oscillations, which will be quoted in detail throughout this text, came the initiative to mathematically model the problem and seek a form of oscillation that may result in a more efficient trapping. Numerical results in a one-dimensional model suggests that the number of atoms is strongly aflected by fuctuations, but we have not found, for the modulations suggests in this work, an oscillation model that could provide an increase of the trap atoms. It was noted that the oscillation frequency of the atom is subjected, aflect the amplitude of the oscillations in the number of trapped atoms.

▼ Contact-free trapping and manipulation of light absorbing micrometer and nanometer-scale particles in air and in vacuum utilises radiation pressure, which results from momentum transfer from photons, and a pressure-dependent thermal force, caused by momentum transfer from gas molecules to the confined particles. Both forces are linearly proportional to the illuminating laser intensity, and both push the particles towards regions of lower intensity. While the radiation pressure of light was predicted and described more than a century ago, the theory of thermal forces, the so called photophoretic force, is still under development. It depends on a number of poorly described factors, such as the temperature gradient across the illuminated particle and thermal creep of heated gas along the particle surface due to temperature and pressure gradients. In this thesis I use doughnut-shaped structured laser beams to levitate and guide light-absorbing micron-size particles aiming to uncover the optically induced forces in air at variable pressure ranging from 10-2000 millibar. First, I designed and built a counter-propagating optical pipeline to uncover the influence of polarisation on the particle movement. Second, I designed and constructed a vertically directed diverging vortex beam trap, a `funnel' trap, to conduct a quantitative evaluation of the photophoretic force and trapping stiffness by levitating graphite particles and carbon-coated glass shells of calibrated sizes in a carefully characterised vortex beam. Third, from the measured size of the particles and the position of the particle in the beam on the one hand, and the known density of the particles and the intensity distribution of the funnel trap on the other hand, I characterised the optically induced thermal forces in the axial and transverse directions. Fourth, I compared the contribution of thermal force to the light-pressure force and their dependence on atmospheric pressure. Based on the results of my experiments I determined the parameter space for guiding particles with hollow-core vortex and Bessel beams, taking into account the particle speed, size, and offset from the laser axis, all linked to the optical beam properties such as beam divergence, optical polarisation and power. The results of this thesis are used in the development of a touch-free optical system for pin-point delivery of macromolecules to the X-ray focal spot at the Free Electron Laser facility at the DESY (Deutsches Elektronen-Synchrotron) synchrotron in Hamburg, Germany, for coherent diffractive imaging experiments on nanometer-scale morphology. I conclude with a discussion of avenues for future work in contact-free manipulating of particles with structured laser beams to enhance significantly the efficiency of nanometer-scale morphology of proteins and…

▼ Recently, Coherent Optical Orthogonal Frequency-division Multiplexing (CO-OFDM) has been considered as a promising technology for high-speed optical transmission due to its easiness of dispersion compensation, high optical spectral efficiency and superior scalability over the channel dispersion and data rate. In this thesis, we conduct analysis on the transceiver nonlinearity impact on a coherent optical Orthogonal Frequency-division Multiplexing (OFDM) system and the feasibility of transmitting up to 1 Tb/s per channel data rate over CO-OFDM WDM systems. We investigate the optimum design for a CO-OFDM transmitter using an optical In-phase/Quadrature (I/Q) modulator and show by simulation that in contrast to the direct-detected system, the optimal modulator bias point for the coherent system is π, or the null point of the modulator. We also propose and demonstrate through simulation a transmitter side digital signal processing technique including digital clipping and digital pre-distortion to compensate the nonlinearity induced by the OFDM peak-to-average power ratio effect and Mach–Zehnder modulator (MZM). Furthermore, we conduct analysis on the study of nonlinearity and dynamic range for a CO-OFDM receiver induced by the imbalance between the two ports of a balanced receiver. The input power dynamic range and tolerance to the relative-intensity-noise (RIN) are analyzed for the coherent balanced-receiver. We then explore the transmission performance for high speed wavelength-division multiplexing (WDM) CO-OFDM systems with up to 1Tb/s per channel data rate under the impact of fiber nonlinearity. We find that the optimum fiber launch power increases almost linearly with the increase of data rate. A 7 dB optimum launch power difference is observed between 107-Gb/s and 1.07-Tb/s CO-OFDM systems. We also investigate the dispersion compensation fiber impact and filter concatenation effect issues when upgrading the 10-Gb/s to the future 100-Gb/s CO-OFDM systems. We identify three contributions to the Q degradation for the inline dispersion compensated WDM systems. We show that due to the high spectral efficiency, 100-Gb/s CO-OFDM signals have very high tolerance to the filter narrowing effect, and are resilient to the group ripples from the filter concatenation effect.

▼ Coherent optical communication systems have already been demonstrated as a promising technique for next-generation optical transport networks. Coherent reception not only supports advanced modulation formats and polarization division multiplexing (PDM) to enhance bandwidth efficiency, but also allows the use of digital signal processing (DSP) algorithms to compensate fibre channel impairments in the electrical domain. Single-carrier PDM quadrature-phase-shift-keying (QPSK) transmission scheme has already been commercialized as solution for 100-G Ethernet. In the meantime, the ever increasing bandwidth requirement is driving the research towards high spectrum-efficient transmission, which leads to the combination of higher-order quadrature-amplitude-modulation (QAM) formats and advanced spectrum shaping techniques. For commercial PDM-QPSK systems, the receiver’s DSP process mainly involves linear fibre channel impairment compensation and carrier recovery, where chromatic dispersion (CD) compensation and polarization de-multiplexing (pol-demux) are realized with separate filters. In particular, the CD filter is with static coefficients and is identical for both polarizations, while pol-demux is usually a multiple-input-multiple-output (MIMO) adaptive process using constant modulus algorithm (CMA). This typical structure has two main issues: (i) the two-stage equalization process is computationally expensive, since in principle these two linear filters can be combined in one step to save the computational circuits; (ii) the CMA algorithm cannot achieve optimal adaptation with high-order QAM formats with non-constant modulus, which requires feedback process or otherwise will cause performance penalty. We first consider optimizing the system performance for the conventional two-stage system with high-order QAM format (especially 16-QAM format). The mis-adjustment between CMA and 16-QAM is derived, and we propose to use multi-modulus algorithm (MMA) in 16-QAM system with fewer mis-adjustment errors. We experimentally verify that with pre-frequency offset compensation, MMA achieves more than 1-dB Q improvement compared to the CMA algorithm. Furthermore, in order to cope with the residual adaptive error, we propose a phase insensitive method namely decision-directed MMA for steady state optimization. Experimental results show that DD-MMA achieves the best performance among all the steady state algorithms. We then present the work to design the DSP circuits with feed-forward, modulation format flexible channel estimation (CE) technique based on training-aided technique (TA-CE). We first derive the optimal TS criterion to achieve minimum mean square error (MMSE) CE performance, and then reliable and robust approaches for frame timing synchronization (FTS) and frequency offset compensation (FOC) are addressed. Then the linear noise removal technique is provided by windowing the time-domain CE taps while reducing the training overhead ratio effectively. Furthermore, we propose to use the polyphase equalizer to achieve…

▼ Magnetic systems with interacting ferromagnetic single-domain elements are a useful landscape to explore a wide range of fundamental and technological phenomena. In this dissertation, we consider a system of interacting ferromagnetic islands with perpendicular anisotropy. Islands are lithographically-deﬁned to be single-domain and are arranged into large arrays with geometries that are geometrically frustrated and unfrustrated. We explore ﬁeld-driven local and global magnetic switching behavior using a home-built diﬀraction-limited magneto-optical Kerr microscope wherein individual islands in each array are isolated, indexed, and tracked in the presence of an applied external ﬁeld. Global and local switching behavior is directly accessed through analysis island switching ﬁelds in the presence of magnetic hysteresis loops. We ﬁrst explore the considerations regarding lithographic deﬁnition of disconnected islands and deposition of Co/Pt multilayers with strong perpendicular anisotropy. The thickness and number of stacked Co/Pt bilayers as well as deposition method signiﬁcantly aﬀect the strength of perpendicular anisotropy. We ﬁnd sputter deposition of a 8-stack bilayer of Co 0.3 nm /Pt 1 nm optimizes strong perpendicular anisotropy with square hysteresis loops. Our experimental sample contains several sets of ordered arrays with varying geometry and inter-island spacing. Each island is single-domain with length scales amenable to Kerr imaging such that magnetic degrees of freedom are optically accessible. We next discuss the development, calibration, and operation of a home-built magneto-optical Kerr microscope. The Kerr microscope uses a xenon stabilized white light source, Glan-Thompson polarizers, and a 100x oil objective lens to illuminate a sample with linear polarized light. A cooled CCD camera receives the reﬂected light and transmits it to the computer in a sequence timed with the application of an external magnetic ﬁeld. We use LabVIEW software to isolate, index, track, and extract intensity information and corresponding switching ﬁelds associated with individual islands in each array as a function of a magnetic ﬁeld. We ﬁnd the switching ﬁeld distribution width is well-ﬁt by a simple model comprising the sum of an array-independent contribution (interpreted as disorder-induced), and a term proportional to the maximum ﬁeld the entire rest of the array could exert on a single island, i.e., in a fully polarized state. This supports the claim that disorder in these arrays is primarily a single-island property.

First, I present the design, implementation and performance analysis of a compact multi-photon endoscope based on a piezo electric scanning tube. A miniature objective lens with a long working distance and a high numerical aperture (~ 0.5) is designed to provide a diffraction limited spot size. Furthermore, a 1700 nm wavelength femtosecond fiber laser is used as an excitation source to overcome the scattering of biological tissues and reduce water absorption. Therefore, the novel optical system along with the unique wavelength allows us to increase the imaging depth. We demonstrate that the endoscope is capable of performing third and second harmonic generation (THG/SHG) and three-photon excitation fluorescence (3PEF) imaging over a large field of view (> 400 µm) with high lateral resolution (2.2 µm). The compact and lightweight probe design makes it suitable for minimally-invasive in-vivo imaging as a potential alternative to surgical biopsies. The second device is a magnetic field sensor with a noise equivalent field of 500 nT based on a tapered fiber in a magnetic fluid (Fe3O4 nanoparticles dispersed in the deionized water). This sensitivity, which is three orders of magnitude better than the previously demonstrated tapered sensors, is achieved by biasing the fluid material with a ≈1 mT magnetic field. In addition, application of an optical modulator and an auto-balanced synchronized detector increased the sensor output signal-to-noise ratio significantly. Furthermore, a novel method is presented to employ the proposed sensor in a distributed scheme. The third biomedical optical system is a wave-front sensor. This device can measure the aberrations of human eye with 0.1 diopter accuracy using a collimated LED and a Shack-Hartman Sensor. Since the proposed designed is see-through, we can confirm the accuracy of spherical and astigmatism measurement by correcting the patient vision using fluidic lenses so that the patient’s vision becomes 20/20. In Chapter VI, a coherent anti-Stoke scattering (CARS) sensing instrument is presented. For CARS sensing we need two synchronized laser sources pump and Stoke. The laser is designed and implemented based on a single cavity mode-locked by a semiconductor saturable absorber mirror (SESAM). The Stoke beam is a wide linewidth supercontinuum generated from a highly nonlinear fiber (HNLF). This type of Stoke laser provides broadband CARS sensing which allow us to spatially resolve different materials at the same time.

▼ Integrated optical isolators are nonreciprocal optical components that allow light to pass in one direction only. They are useful in conjunction with lasers, as they block undesired reflections from entering the laser cavity, where it might destabilize the device. Optical circulators are extensions of isolators, as they reroute the backwards propagating light into another direction. Thus, they can be used to separate counterpropagating signals. Both devices have many uses in photonic integrated circuits, but are challenging to implement, due to the reciprocal nature of most semiconductor and dielectric materials.Magnetic materials such as garnets can break the symmetry and are well suited for optical isolators and circulators. However, they are difficult to integrate with silicon, III-V, and other commonly used optical materials. Heterogeneous integration through wafer bonding can overcome this obstacle and is used successfully in this work to achieve integrated optical isolators and circulators on silicon with record performance. This is done through waveguide optimization, careful process development, and a novel idea to integrate the source of magnetic fields, an electromagnet, directly onto the chip. This not only shrinks the footprint of the devices, but also provides flexibility in design as well as wavelength tunability, which is critical if the device is to be used in a circuit.Two flavors of the isolator and circulator are presented. One is a resonant device using a microring that can achieve up to 32dB of isolation. Slight modifications to the design can result in a microring optical circulator as well, a first to the best of our knowledge. The other device architecture is a nonresonant device using a Mach-Zehnder interferometer. While these devices have larger footprint, they can achieve optical isolation over 20dB over a wide wavelength range of 18nm. This is extremely useful in applications such as data transmission, where backwards propagating light may be spread over several nanometers. Of course, the isolator should be paired with a laser to realize its true potential. Several design and fabrication challenges stand in the way of this, which are addressed in this work. Polarization rotators are implemented to match the operating polarization between the laser and the isolator, and fabrication is carefully tailored such that both devices can be integrated on the same chip. Preliminary results show that the laser and isolator integration can happen in the near future. Such a demonstration would open up new opportunities in photonic integrated circuits, and would be of great interest in optical communications, sensing, RF photonics, as well as new, unexplored fields.
