▼ In this dissertation, a novel semiconductor mode-locked oscillator which is an extension of eXtreme Chirped Pulse Amplification (XCPA) is investigated. An eXtreme Chirped Pulse Oscillator (XCPO) implemented with a Theta cavity also based on a semiconductor gain is presented for generating more than 30ns frequency-swept pulses with more than 100pJ of pulse energy and 3.6ps compressed pulses directly from the oscillator. The XCPO shows the two distinct characteristics which are the scalability of the output energy and the mode-locked spectrum with respect to repetition rate. The laser cavity design allows for low repetition rate operation <100MHz. The cavity significantly reduces nonlinear carrier dynamics, integrated self phase modulation (SPM), and fast gain recovery in a Semiconductor optical Amplifier (SOA). Secondly, a functional device, called a Grating Coupled Surface Emitting Laser (GCSEL) is investigated. For the first time, passive and hybrid mode-locking of a GCSEL is achieved by using saturable absorption in the passive section of GCSEL. To verify the present limitation of the GCSEL for passive and hybrid mode-locking, a dispersion matched cavity is explored. In addition, a Grating Coupled surface emitting Semiconductor Optical Amplifier (GCSOA) is also investigated to achieve high energy pulse. An energy extraction experiment for GCSOA using stretched pulses generated from the colliding pulse semiconductor mode-locked laser via a chirped fiber bragg grating, which exploits the XCPA advantages is also demonstrated. Finally, passive optical cavity amplification using an enhancement cavity is presented. In order to achieve the interferometric stability, the Hänsch-Couillaud Method is employed to stabilize the passive optical cavity. The astigmatism-free optical cavity employing an acousto-optic modulator (AOM) is designed and demonstrated. In the passive optical cavity, a 7.2 of amplification factor is achieved with a 50 KHz dumping rate. Advisors/Committee Members: Delfyett, Peter.

Les lasers à cavité verticale émettant par la surface (VCSEL) à base d'antimoniures dans le moyen infrarouge permettent le développement et l'amélioration d'applications telles que la détection de gaz polluants. De nouveaux miroirs à réseaux à haut contraste d'indice (HCG) ont montré un pouvoir réflecteur comparable voire supérieur aux miroirs de Bragg conventionnels avec un gain d'épaisseur d'un facteur 10 tout en offrant un effet polarisant. L'insertion de ce nouveau type de miroir au sein d'une structure VCSEL présente ainsi des avantages prometteurs pour améliorer les propriétés de ces composants pour une émission dans le moyen infrarouge. Le travail présenté dans ce manuscrit de thèse concerne la conception de miroirs HCG qui répondent aux exigences d'une intégration VCSEL en prenant en compte les contraintes technologiques et la tolérance aux erreurs de fabrication. Pour cela, dans un premier temps, un algorithme d'optimisation global a été combiné à une méthode de simulation numérique de réseaux (RCWA) afin d'automatiser la conception de miroirs. L'étude précise des tolérances des paramètres géométriques du réseau a été menée pour pouvoir ensuite développer un algorithme d'optimisation robuste. Cet algorithme permet ainsi d'obtenir non seulement un miroir répondant aux exigences de réflectivités définies par l'utilisateur mais également de conserver ces performances pour de larges gammes de tolérances. Enfin, dans une dernière partie, l'intégration du miroir à réseau dans un VCSEL a été simulée par une méthode aux différences finies (FDTD) pour étudier le fonctionnement d'un composant complet.

In the mid infrared wavelength range, Vertical Cavity Surface Emitting Lasers (VCSEL) based on the antimony alloy is a promising solution to develop and enhance numerous applications such as polluting gas sensing. A new type of mirror based on High Contrast Grating (HCG) structures has shown similar reflectivities than the Bragg mirrors which are usually used in VCSELs. However, with a polarization selectivity and a reduction in thickness of a factor of 10, HCG mirrors can advantageously replace Bragg reflectors to enhance the properties of mid infrared VCSEL structures. The work presented in this manuscript is devoted to the design of high contrast grating mirrors for a VCSEL application and takes precisely into account the technological constraints and tolerance of fabrication. In a first part, a global optimization algorithm has been combined to a numerical analysis of grating structures (RCWA) to automatically design HCG mirrors for a VCSEL application. In a second part of this work, the tolerances of the grating dimensions have been precisely studied which has lead to the development of a robust optimization algorithm. This algorithm allows to design high contrast gratings which exhibit not only a high efficiency but also large tolerance values required by the manufacturing process. Finally, in a last part, a VCSEL structure using a high contrast grating as top mirror has been designed and simulated by FDTD to…

▼ Future high speed communications networks will transmit data predominantly over optical fibres. As consumer and enterprise computing will remain the domain of electronics, the electro-optical conversion will get pushed further downstream towards the end user. Consequently, efficient tools are needed for this conversion and due to many potential advantages, including low cost and high output powers, long wavelength Vertical Cavity Surface Emitting Lasers (VCSELs) are a viable option. Drawbacks, such as broader linewidths than competing options, can be mitigated through the use of additional techniques such as Optical Injection Locking (OIL) which can require significant expertise and expensive equipment. This thesis addresses these issues by removing some of the experimental barriers to achieving performance increases via remote OIL. Firstly, numerical simulations of the phase and the photon and carrier numbers of an OIL semiconductor laser allowed the classification of the stable locking phase limits into three distinct groups. The frequency detuning of constant phase values (ø) was considered, in particular ø = 0 where the modulation response parameters were shown to be independent of the linewidth enhancement factor, α. A new method to estimate α and the coupling rate in a single experiment was formulated. Secondly, a novel technique to remotely determine the locked state of a VCSEL based on voltage variations of 2mV−30mV during detuned injection has been developed which can identify oscillatory and locked states. 2D & 3D maps of voltage, optical and electrical spectra illustrate corresponding behaviours. Finally, the use of directly modulated VCSELs as light sources for passive optical networks was investigated by successful transmission of data at 10 Gbit/s over 40km of single mode fibre (SMF) using cost effective electronic dispersion compensation to mitigate errors due to wavelength chirp. A widely tuneable MEMS-VCSEL was established as a good candidate for an externally modulated colourless source after a record error free transmission at 10 Gbit/s over 50km of SMF across a 30nm single mode tuning range. The ability to remotely set the emission wavelength using the novel methods developed in this thesis was demonstrated. Advisors/Committee Members: Corbett, Brian, Peters, Frank H., SFI.

This dissertation demonstrates the usage of localized surface plasmon (LSPR) and grating-coupled surface plasmon resonance (GCSPR) to enhance the photocatalytic activity of a thin film photocatalyst, particularly TiO_2 (P25), and the performance of thin film organic photovoltaic. In the first study, we show the improvement of the photocurrent of the TiO_2 photocatalyst film in water splitting reaction by using localized surface plasmon of gold nanoparticles. We prepared plasmonic gold nanoparticle (AuNP)–TiO_2 nanocomposite and deposited on transparent-conductive electrode (indium-tin-oxide (ITO) coated glass) to obtain AuNP–TiO_2 nanocomposite photoelectrocatalytic (PEC) electrode with the thickness of ～460 nm. The photocurrent that originates from the water-splitting reaction catalyzed by LSPR of the gold nanoparticles affected the generation of photocurrent by TiO_2 upon illumination with visible light was systematic measured. Using electrochemical impedance spectroscopy (EIS), the results suggest that the improvement in the photocurrent generation creates from an enhancement in electron–hole pair generation, which induced by the LSPR of the plasmonic gold nanoparticles, rather than the extension of the electron lifetime. Moreover, we not only show the effect of LSPR in enhancement of the photocurrent of TiO_2 under visible illumination but also introduced a new method to enhance the photocurrent of TiO_2 by a multiple plasmonic effect, i.e., the cooperation of LSPR of plasmonic gold nanoparticles and the GCSPR of a gold grating. For the second study, we emphasize on the improvement of the photocurrent and the photo-electricity conversion efficiency of thin film P3HT:PCBM solar cells by GCSPR. The Blu-ray disc recordable (BD-R) and Blu-ray disc (BD) grating pattern (Λ = 330 nm) were created on the active layer of the solar cell using pressure-less nanoimprinting technique, following by thermal evaporation of aluminum to obtain the BD-R and BD grating back electrode. The surface plasmon (SP) reflectivity curves of the fabricated solar cell reveal the decrease of the reflection spectra of the solar cells with BD-R and BD grating compare with the flat device. This can be implied to the increase of the trapped light in the device due to the BD and BD-R grating structures that can be assigned to two regions included (i) the increase of the light trapping at 400 – 650 nm attributed to the light scattering effect. (ii) The irradiation photon can be coupled into GCSPR that propagates along the surface of the diffraction grating which can be observed as the occurrence of the dip peaks at the wavelength longer than 650 nm. The I-V characterization results show the improvement of photocurrent about 10% and 5.6% for the BD-R and BD solar cell, respectively. Moreover, the enhancement of the photoconversion efficiency of 19.3% can be obtained from BD-R solar cell while those of solar cell with BD grating can be improve the photoconversion efficiency of…

▼ Semiconductor metal nanocavity lasers and light emitting diodes together with novel modal cutoff confinement light emitters are investigated for optical interconnection application in future dense photonic integrated circuits. Several different cavity structures are designed, processed, and characterized, and demonstrate operation with current injection at room temperature. We first examined metal-cavity quantum-dot surface-emitting micro-lasers. Different sizes of metal-DBR cavities are fabricated with cavity volume reduction both in the lateral and vertical dimensions following our theoretical design rules to optimize the performance. One of the smallest electrical injection lasers is demonstrated with a minimum diameter of 1-m and a minimum hybrid DBR-Ag mirror of only 5.5 pairs. From the analysis of various sizes of diameter devices, it is found that self-heating is significant in the smaller diameter devices due to both the higher series resistance and higher threshold gain leading to a high carrier density. For the further cavity volume reduction, we have designed, fabricated, and characterized metal-encapsulated nano-light-emitters with bulk semiconductor in the active region. The first principal design rule is used to estimate the fundamental mode resonance and threshold condition. The result based on this design rule agrees very well with the numerical three-dimensional calculation. The device recipes have been developed through multiple iterations from the device characterization. The smallest metal cavity diode emitter with electrical injection is 0.086 03 in terms of emitting wavelength at room temperature. It is shown that the series resistance of metal-encapsulated nanocavities is much smaller than the metal coated VCSEL, suppressing the heat generation for the small diameter devices. The fabrication improvement shows a narrow linewidth cavity mode in the metal nanocavity with a volume of 1.23 03 at room temperature. To solve the problem of the high radiation loss caused by a metal mirror, we proposed novel nano/micro-cavities edge-emitting laser using the mode-cutoff reflection of the fundamental TE mode from a metal-semiconductor-metal (MSM) region. The devices are examined by multiple aspects for their function, both qualitatively from the principle of operation and quantitatively from the analytical study of reflection coefficient and numerical simulations by the 2D and 3D models for practically designed devices. The numerical simulations including the metal loss suggest that room temperature lasing with a reasonable threshold material gain is achievable. We have also developed processing recipes to fabricate the device without any semiconductor dry-etching process. The preliminary electrical and optical characterizations of the proposed devices are performed showing excellent I-V characteristics with a thin hetero-junction diode. The light output curve shows a super-linear behavior suggesting possible lasing in the cavity volume less than 3.

L’objectif de cette thèse est de développer un nouveau matériau photopolymère pouvant être microstructuré dans la gamme de longueur d'onde du proche infrarouge (NIR). Le but final de ce travail est de proposer des solutions innovantes pour l'intégration de micro-optique sur les VCSELs (Vertical-Cavity Surface-Emitting Laser), sources lumineuses miniaturisées utilisées dans de nombreuses applications en optique, photonique, capteurs ou biologie. Le verrou technologique principal a consisté à développer et étudier le photopolymère adéquat pour la microfabrication déclenchée par le VCSEL. La difficulté principale tient à la longueur d'onde de photopolymérisation qui est fixé par le VCSEL et qui a obligé à développer un système moléculaire nouveau pour une polymérisation radicalaire à 780 et 850 nm. Une part importante du travail a consisté à étudier les mécanismes photophysiques et photochimiques des matériaux permettant de proposer des systèmes efficaces, sur le plan de la photophysique, de la photochimie de photopolymérisation et également une approche originale a été développée pour appréhender de façon quantitative les phénomènes de diffusion du colorant dans la matrice polymère. Sur la base des systèmes moléculaires proposés, la démonstration de l'intégration de microlentilles sur VCSEL par ce procédé innovant a pu être démontré. Les VCSELs lentillés ont été caractérisés et des propriétés très intéressantes pour la focalisation ont été démontrées.

The objective of this thesis is to develop a new photopolymer material that can be microstructured in the wavelength range of near-infrared (NIR). The ultimate aim of this work is to propose innovative solutions for micro-optical integration on VCSELs (Vertical-Cavity Surface-Emitting Laser). These miniaturized light sources are used in many applications in optics, photonics, sensors or biology. The main technological challenge was to develop and explore a new photopolymer compatible with a microfabrication initiated by the VCSEL. The main difficulty was to develop a new molecular system for radical polymerization at 780 and 850 nm, which is the wavelength emitted by the VCSEL. An important part of the work consisted to study the photophysical and photochemical mechanisms of this photopolymer in order to provide efficient systems in terms of photophysics, photochemistry of the photopolymerization. An original approach was developed to quantitatively apprehend the phenomena dye diffusion in the polymer matrix. Based on the proposed molecular systems, demonstrating the integration of microlenses on VCSELs by this innovative process could be shown. The lensed VCSELs have been characterized and very interesting properties for focusing have been demonstrated.

In this study, the design and fabrication of a monolithic InP-based 1550-nm photonic-crystal surfaceemitting laser (PCSEL) is reported. The device is composed by an InGaAsP multi-quantum well (MQW) active layer and InP photonic crystal (PhC) formed by metal organic chemical vapour deposition (MOCVD). A theoretical study based mainly on the Fourier modal method using Stanford Stratified Structure Solver (S 4) and finite element analysis using COMSOL Multiphysics was carried out in order to optimize the emission at 1550 nm due to the two-dimensional band-edge resonance effect at the Γ point.The device design and modeling, materials testing (annealing and MOCVD regrowth), process optimization and the fabrication of light emitting diodes (LEDs) based on the same structure as the PCSELs (without the PhC) is reported. The fabricated devices show a low series resistance of 8.19 Ω and a turn-on voltage of 0.84 V. The average differential output power is 41 mW/A with an electroluminescent peak at 1511 nm. The full assembly of the final PCSEL devices is beyond the scope of the present thesis and corresponds to an ongoing project expected to be finalized within the coming year. However, detailed guidelines and fabrication instructions, including the manufacturing of an appropriate lithographic mask set, are provided.

Föreliggande examensarbete rapporterar designen och tillverkningsprocessen för en monolitisk InPbaserad 1550-nm så kallad Photonic-Crystal Surface-Emitting Laser (PCSEL). Komponenten bestå r av en aktiv kvantbrunnsstruktur i InGaAsP och ett fotoniskt-kristall (PhC)-lager i InP, bägge odlade med hjälp av metalorganisk gasfasepitaxi (MOCVD). En teoretisk studie baserad på Fourier-modalmetoden med användning av Stanford Stratified Structure Solver (S4) och finit elementanalys-metoden med med hjälp av av COMSOL Multiphysics utfördes för att optimera emissionen vid 1550 nm genom en tvådimensionell bandkantsresonanseffekt vid Γ punkten.Rapporten går igenom komponentdesign och modellering, materialtestning (värmebehandling och MOCVDåterväxt), processoptimering och tillverkning av lysdioder (LED) baserade på samma struktur som PCSELkomponenterna (men utan PhC-strukturering). De tillverkade lysdioderna uppvisar en låg serieresistans på 8.19 Ω och en framspänning på 0.84 V. Den genomsnittliga differentiella utgångseffekten är 41 mW/A med en luminescenstopp vid 1511 nm. Den slutliga tillverkningen av färdiga PCSEL-enheter ligger utanför ramen för detta examensarbete och motsvarar istället ett pågående projekt som förväntas bli slutfört inom det kommande året. Däremot ges detaljerade riktlinjer och tillverkningsinstruktioner, för vilket ett fotolitografiskt mask-set även tagits fram.

▼ The vertical-cavity surface-emitting laser or VCSEL is a special type of diode laser, which has established itself in optoelectronic applications asa low-cost, high-quality miniaturized light source. The development of VCSELs can be largely promoted with support from computer simulations. In this study, we have used such simulations, on one hand to understand and improve the VCSEL performance, and on the other hand to prepare for analyzing new device concepts such as transistor-VCSELs. This thesis starts with a background introduction to the principle idea of VCSELs and then states the significance of this simulation work.Then it briefly introduces the previously used simulation workbench Sentaurus and explains the mathematical approach and the computation methods of the finally chosen simulator PICS3D. The case study of a fabricated and characterized epitaxially regrown VCSEL is the major component of this work. First the device configuration is demonstrated with detailed discussion on several design features. Second the physical models of electrical, optical and thermal phenomena along with their key parameters are presented and so are the advanced models for the active region. The main results of simulation, including steady-state characteristics and small-signal modulation, show good agreement with the experimental results and reveal some imperfections of the device design and processing, such as the overestimated stability of the regrown junction and the variation of cavity length caused by over-etch. This work is also treated as an evaluation of the simulator PICS3D, and two problems are identified: one is the troublesome way to construct a 3D device by coupling several 2D layer structures together, requiring the mesh for each layer structure to be compatible; the other would be the tricky boundary setting for the adopted method, Effective Index Method (EIM), for the transverse field calculation when only a weak index guiding effect exits in the cavity. Finally, we summarize this work and suggest some tasks for further simulations.

▼ The mobile communication networks in 5G and beyond aim to provide better reliability, improve the coverage, and increase the communication speed. The number of users increases drastically. In 5G, the number of base stations, called Transmission Reception Point (TRP) in 5G, will increase dramatically, and smaller sells will be used. The central station (CS) must be placed in an easily accessible and securely maintained location. Implementing this scenario will increase the cost rapidly and would be challenging to manage, troubleshoot, and monitor. As an alternative, the central station can be placed in a central location and can be accessed easily. Only the TRP will placed in the location. The TRP then should be connected to the central station using Radio over Fiber (RoF) links. The TRP unit should be as simple as possible since this will lower the cost and increase the reliability. Orthogonal Frequency Division Multiplexing (OFDM) has been chosen as the main waveform to be implemented in 5G as a transmission technique. OFDM is compatible with Multiple Input Multiple Output (MIMO), which is the key factor in the new generation communication systems. The large bandwidth and spectrum allocation of OFDM are suitable for 5G requirements. However, the bandwidth of the wireless systems is still limited compared with very high bandwidth that can an optical transmission link provide. Since the bandwidth of 5G antennas is very wide, it is possible to send multiple technologies in the same fiber link from the central station to the TRP unit. For instance, in the same link, WiMax, WiFi, 4G, and 5G signals can be transmitted simultaneously. In the TRP unit, all these signals can be optically received and wirelessly retransmitted at the same time. This approach will reduce costs dramatically, increase the reliability, and reduce the need to monitor and maintain each technology separately. In the previous approach, a reliable light source that can provide high-speed rate is crucial. The best candidate in this situation would be the Vertical-Cavity Surface-Emitting-Laser (VCSEL). VCSEL has many advantages such as low fabrication and packaging costs, high performance, high efficiency, easy fiber coupling, and large modulation bandwidth. However, VCSELs have some disadvantageous such as polarization instability, which is sometimes known as polarization switching, low output power, relative noise intensity, and nonlinearity. Sending multiple signals into the same optical system (transmitter, fiber link, and photodetector) will create unwanted harmonics which will deteriorate the analogue performance drastically. The primary source of nonlinearity in the Rof link of is the VCSEL. The second-order harmonic distortion and third-order intermodulation distortion are considered to be the main drivers of nonlinearity inside the VCSEL. To suppress the nonlinearities in the VCSEL or come around it. Multiple workarounds have been proposed. Different VCSELs have different harmonic distortion minima at different frequencies and different…

▼ As gas prices continue to rise and fossil fuels pollute our environment, various alternative fuel sources are being actively pursued. Hydrogen shows considerable promise due to its virtually unlimited supply, energy conversion efficiency, and potentially neutral impact on the environment. However, due to the flammability of hydrogen gas in concentrations as low as 4% in air, reliable sensors capable of detecting small concentrations of hydrogen with quick response times are a necessity. Photonic-based gas sensors have a wide assortment of advantages over other sensing mechanisms due to their high sensitivity and quick response time. Therefore, several platforms in which semiconductor lasers can be functionalized to detect hydrogen concentrations below the lower explosive limit have been developed. The laser structures were chosen such that there already exist well-established fabrication technologies, and the functionalization method was designed to be easy, practical, and inexpensive so that these devices can be mass produced using existing technologies. Four different types of hydrogen sensors utilizing thin films of palladium integrated within the structures of semiconductor lasers have been studied. This study includes the design, simulation, fabrication, characterization, and optimization of the devices. The palladium catalyst layer is well known to react to hydrogen gas, forming palladium hydride with optical properties dependent on the hydrogen concentration. This reaction yields a change in complex refractive index and thus also the laser’s output power and peak wavelength. The advantages of these sensors are their small size, high sensitivity, wide dynamic range, inline integration, and scalability to arrays. This thesis is organized into four sections. First, a brief analysis of the rising importance of hydrogen energy sources is presented, followed by an overview of the current state of hydrogen sensing technologies discussing the advantages and disadvantages of each method. Then, a description of the testing setup and procedure common to all device types is presented. Afterward, an in-depth overview is presented of each of the sensors in terms of the device designs, simulation methods and results, fabrication processes, and experimental measurement results. Finally, comparisons of these device designs are offered and conclusions are made. Advisors/Committee Members: Goddard, Lynford L. (advisor), Goddard, Lynford L. (Committee Chair), Choquette, Kent D.

▼ Metallic nanoparticles due to surface plasmon effects are used to fabricate devices with particular electro-optic properties, so that, they have been widely studied in many fields. With progressive developments of interesting phenomena and applications, metallic nanoparticles have become an important role in different kinds of the studies. One interesting application is the surface enhanced Raman scattering associated with metallic nanoparticles. It is worthy to investigate the relationship between the surface plasmon effects of metallic nanoparticles and the enhancement mechanism of the Raman scattering. Besides, the shape effects of metallic nanoparticles in an array are interesting for a combination with optical circuits. On the basis of these properties of metallic nanoparticles, two studies will be introduced in this dissertation: First, the intensity of surface-enhanced Raman scattering (SERS) light of crystal violet (CV) molecules are probed as the molecules adsorbs on silver nanoparticles with SiO2 coating. We find that the intensity of the SERS light from CV molecules varies with the thickness of the SiO2 coating. Hence, this experiment investigates the enhancement mechanism of surface enhanced Raman scattering by modulating the thickness of the SiO2 coating. In addition, the SiO2 coating can work as a preventer to remain the activity of the silver nanoparticles. This makes the silver nanoparticles with SiO2 coating as a reusable substrate, which can provide a possibility to increase the precession of SERS measurements. Second, a gold nanoparticle grating is fabricated by lithographic method. The shape effect of gold nanoparticles in the grating is investigated by probing the diffraction light intensity of the array. A variation of the diffraction light intensity of the grating is revealed as rotating the polarization of the probe light. And, the peak of the diffraction spectra shifts with the increasing of the polarization angle of the probe light. Under observation of the SEM, gold nanoparticles of an ellipsoid-like shape are shown and the major axis of gold nanoparticles are parallel a direction with an averaged angle of 57.8o respect to grating direction. We thus considerably thought that this the varying of the diffraction spectra are attributed to the shifts of localized surface plasmon resonance. In addition, the boundary effect on the shape of gold nanoparticles in the grating is explored.
