Esta dissertação de mestrado propõe duas técnicas de modulação para Conversores Multiníveis Modulares (MMC). A primeira estratégia consiste na modulação por disposição de fase (phase disposition). Nesta estratégia os sinais modulantes recebem os sinais offset necessários para estabelecer o equilíbrio das tensões dos capacitores e controle das correntes internas dos sub-braços. Como estratégia de controle da corrente interna desenvolveu-se um controlador por histerese, mantendo seu valor limitado a níveis estabelecidos de acordo com a referência. Já a estratégia de controle das tensões nos capacitores é realizada a partir de um algoritmo no qual se ordena as tensões dos capacitores em ordem ascendente, após, se define os offsets de tensão a serem aplicados, a fim de carregar os capacitores que apresentem menor tensão e descarregar os que tiverem maior tensão. A segunda estratégia proposta foi baseada na modulação por deslocamento de fase (phase-shift) para o conversor MMC cujo submódulo é formado pelo conversor com capacitores flutuantes (flying capacitor). Foram desenvolvidas estratégias para controlar a corrente interna do conversor, através de um controlador proporcional integral e também um proporcionalintegral ressonante que atenua as componentes harmônicas de 2 e 4 ordem presentes nas correntes internas. Também foram desenvolvidas estratégias para controlar as tensões nos capacitores internos e externos dos submódulos.

This thesis proposes two modulation techniques for the Modular Multilevel Converter (MMC). Where the modulating signals are compared to a carrier, generating the signals for the power switches. In this strategy the modulating signals receive the signals required to stability the capacitor voltage balance and control the internal currents of the sub-arms. As a strategy for controlling the internal current a controller was developed by hysteresis, keeping its value close to a reference value. The strategy of controlling the voltages in the capacitors is made from an algorithm in which the voltages of the capacitors are ordered in ascending order, after defining the voltage offsets to be applied in order to charge the capacitors lower voltage and discharge those with higher voltage. The second proposed strategy was based on the phase-shift modulation (PS) for the MMC converter whose sub-module is formed by the converter with flying capacitor. Strategies have…

Resumo: Os giroscópios interferométricos a fibra óptica (IFOGs) são partes fundamentais dos sistemas de navegação inercial, utilizados no controle de atitude de satélites e navegação de foguetes, submarinos, aviões e mísseis. Esses dispositivos estão sujeitos a embargos de comercialização internacional, sendo o domínio dessa tecnologia fundamental para garantia da soberania do Brasil. Nesta tese, é apresentado o desenvolvimento de um novo sistema eletrônico para IFOGs de malha fechada de classe inercial, que inclui o circuito de modulação, demodulação, controle e comunicação, bem como, novas técnicas de modulação, condicionamento e processamento de sinais. Foi realizada uma análise detalhada das não idealidades do sistema de modulação: não linearidade, modulação de intensidade do modulador opto-integrado (MIOC) e reflexões na interface MIOC/interferômetro de Sagnac. Objetivando minimizar os efeitos negativos destas não idealidades, foi proposta uma nova técnica de modulação baseada na modulação de dois níveis. Essa nova técnica preserva todas as vantagens da modulação de dois níveis clássica (não gera offsets significativos devido às reflexões ópticas e maximiza o fundo de escala do IFOG) e elimina sua limitação (controle do fator de escala deficiente em baixas velocidades angulares). Também é apresentado neste trabalho, um modelo teórico para o angle random walk (ARW) de IFOGs com modulação digital. Esse modelo permite: estimar o ARW de um giroscópio a partir de suas configurações ópticas e eletrônicas, identificar a profundidade de modulação que minimiza o ARW para uma determinada potência óptica e estimar a melhoria no ARW com o aumento da potência óptica. Além disso, o modelo proposto permite identificar quais componentes limitam o desempenho do sistema. Foi construído um circuito eletrônico completo para IFOGs, nos quais todas as técnicas propostas foram implementadas. O sistema eletrônico desenvolvido neste trabalho é consideravelmente mais simples do que os desenvolvidos anteriormente e apresenta desempenho excepcional, sendo capaz de amostrar o sinal de Sagnac com excelente resolução e baixo ruído. ...Observação: O resumo, na íntegra, poderá ser visualizado no texto completo da tese digital

Resumo: A crescente demanda do mercado por um maior aproveitamento da capacidade de transmissão dos sistemas ópticos faz com que técnicas de modulação avançadas sejam cada vez mais consideradas em aplicações práticas. Dentre suas vantagens, tem-se uma melhora significativa na eficiência espectral, na resistência contra diversos efeitos não-lineares e fontes de ruído, assim como uma diminuição na frequência de operação da eletrônica empregada no sistema. Com isso em vista, buscou-se a realização de uma análise completa das principais propriedades de diversas técnicas de modulações avançadas, baseadas na manipulação tanto da amplitude como da fase do sinal óptico e utilizadas em conjunto com sistemas de multiplexação por polarização e comprimento de onda. Nos testes laboratoriais, o objetivo foi a caracterização de um Modulador IQ, responsável pela geração de sinais modulados em 64QAM, 16QAM e DQPSK, bem como de diversos outros componentes necessários para a implementação de um sistema de comunicação óptico coerente completo. Dessa forma, a estrutura básica do sistema foi analisada e compreendida para que em trabalhos futuros sua implementação seja concluída e testes mais detalhados possam ser realizados

The market¿s increasing demand for high capability optical systems requested advanced modulation techniques considered in practical applications. Among its advantages, a significant improvement in spectral efficiency, immunity against various nonlinear effects and noise sources were obtained with a decrease in the operation frequency of the electronics. With that in mind, we sought to conduct an analysis throughout the key properties of various advanced modulation techniques, based on the manipulation of both the amplitude and the phase of the optical signal, and used together with multiplexing systems for polarization and wavelength. Many laboratory tests were made with the objective of characterizing an IQ Modulator, responsible for generating DQPSK, 16-QAM and 64-QAM signals, as well as many other components required for the implementation of a complete coherent optical communication system. Thus achieving the understanding of the system¿s basic structure, the realization of a more complete and detailed set of tests will be possible

This work presents a DC-DC high gain boost interleaved topology built with output film capacitors in order to be used for supplying non-linear loads and is modulated by a DSP programmed with Simulink blocks. The studied converter can supply single phase and three phase inverters. The interleaving technic in DC-DC converters requires a much lower output capacitance, allowing the use of film capacitors, whose life-time is twice bigger than the electrolytic capacitors. Based on the studied converter, qualitative and quantitative analisys were performed. The quantitative analisys was used to develop a project example with 1 kW power, 60 V input voltage, and 400 V output voltage. An prototype was built based on the project for experimental results harversting. The experimental results were properly compared to simulation results and theoretical waveforms. The experimental results validated the proposed converter, because its waveforms were similar to the ones documented in the theoretical analisys.

▼ Enabled by continued device scaling in CMOS technology, more and more functions that were previously realized in separate chips are getting integrated on a single chip nowadays. Integration on silicon has opened the door to new portable wireless applications, and initiated a widespread use of these devices in our common everyday life. Wide signal bandwidth, high linearity and dynamic range, and low power dissipation are required of embedded data converters that are the performance-limiting key building blocks of those systems. Thus, power-efficient and highly-linear data conversion over wide range of signal bands is essential to get the full benefits from device scaling. This continued trend keeps innovation in the design of data converter continuing. Traditionally, delta-sigma modulation data converters proved to be very effective in applications where high resolution was necessary in a relatively narrow signal band. There have been active research efforts across academia and industry on the extension of achievable signal bandwidth without compromising the performance of these data converters. In this dissertation, architectural innovations, combined with effective design techniques for delta-sigma modulation data converters, are presented to overcome the associated limitations. The effectiveness of the proposed approaches is demonstrated by test results for the following state-of-the-art prototype designs: (1) a 0.8 V, 2.6 mW, 88 dB dual-channel audio delta-sigma modulation D/A converter with headphone driver; (2) an 88 dB ring-coupled delta-sigma ADC with 1.9 MHz bandwidth and -102.4 dB THD; (3) a multi-cell noise-coupled delta-sigma ADC with 1.9 MHz bandwidth, 88 dB DR, and -98 dB THD; (4) an 8.1 mW, 82 dB self-coupled delta-sigma ADC with 1.9 MHz bandwidth and -97 dB THD; (5) a noise-coupled time-interleaved delta-sigma ADC with 4.2 MHz bandwidth, -98 dB THD, and 79 dB SNDR; (6) a noise-coupled time-interleaved delta-sigma ADC with 2.5 MHz bandwidth, -104 dB THD, and 81 dB SNDR. As an extension of this research, two novel architectures for efficient double-sampling delta-sigma ADCs and improved low-distortion delta-sigma ADC are proposed, and validated by extensive simulations.

In power electronic applications direct AC/AC conversion plays an important role. This direct AC/AC conversion provides inherent attractive characteristics. There is no need of DC link capacitor. Also four quadrant operation, reduced input distortion and high output power density are feasible in this power conversion. It has many advantages over rectifier fed inverter system. In this research work voltage transformation ratio of the matrix converter is improved. Here space vector pulse width modulation technique is used to improve the quality of the output voltage. Also the space vector pulse width modulation technique is used to operate the matrix converter. In this thesis voltage source inverter and matrix converter performance are described. Single phase matrix converter is synthesized to realize the operation of three phase matrix converter. Performance of single phase matrix converter based on voltage transformation ratio is described. Digital Logic Combination Circuit (DLCC) is proposed for single phase matrix converter. The main objective of this research work is to increase in voltage transformation ratio of the matrix converter using space vector pulse width modulation technique. Open loop analysis of three phase matrix converter is carried out. Three phase matrix converter is simulated for R, RL and induction motor load. Results are compared with voltage source inverter and simulation results are provided. Fuzzy logic based dq axis controller is proposed to get space vector pulse width modulation pulse for three phase matrix converter. Matrix converter switching sequence is selected based on Space Vector Pulse Width Modulation (SVPWM) technique. The analysis of input and output waveforms identifies the constraints that need to be eliminated to ensure successful operation of the matrix converter. This AC/AC conversion system is proposed as an effective replacement for the conventional AC-DCAC system which employs two-step power conversion newline

M.Ing.

The transmission of digital data at higher data rates and greater reliabilities is becoming increasingly more important in the society of today. The usage of, especially wireless digital data, is increasing at an alarming rate, and the need arises for more bandwidth to be made available for this purpose. Hence, the need arises to optimise and expand the usage of bandwidth currently under use. Existing wireless channels, such as the commercial FM service, need to be re-evaluated and unused bandwidth needs to be developed and used as close to capacity as possible. In this dissertation, a study was launched to develop the FM SST (Supplementary Signal Transmission) commercial analog service as a simplex digital channel that can commercially be used to transmit a myriad of digital data. With the help of a commercial FM radio channel, digital data was transmitted using a number of different modulation schemes to obtain channel measurements for the FM SST channel. The modulation scheme that performed the best, given certain criteria, was GMSK. This raw information was then used to extract first and higher order statistical information from the channel, in order to parameterise discrete channel models, based on a Markov process. The channel models that were used were the Gilbert, GilbertElliott and Fritchman channel models. These channel models were then tested according to their iirst and higher order statistical data to evaluate their effectiveness in modelling the error process on the FM SST channel. It was found that the channel model best approximating the real channels was the Gilbert channel. Once satisfactory results were obtained, these discrete channel models were then used to evaluate various error correction schemes for their ability to correct burst errors on the FM SST channel. From the various schemes evaluated, a (63,39) BCH with an interleaver of index 4 was found to perform the best. The purpose of which is to transmit digital data at the highest data rate possible and at the same time having a bit error rate less than lxl0-6.

▼ [ES] Los sistemas de transmisión óptica no-coherente se emplean actualmente en las redes ópticas de corto alcance (< 80 km), como son las redes de ámbito metropolitano. La implementación más común en el estado del arte se basa en sistemas que emplean multiplexación por división en longitud de onda (WDM, wavelength division multiplexing) de cuatro longitudes de onda (¿) proporcionando un régimen binario de 100 Gbps (4¿×25 Gbps). En los últimos años, los sistemas de transmisión ópticos no-coherentes están evolucionando desde 100 Gbps a 400 Gbps (4¿×100 Gbps). Dado que este mercado comprende un gran número de sistemas, el coste es un parámetro importante que debe ser lo más bajo posible. El objetivo de esta tesis es investigar distintos aspectos del procesado de señal en general y, específicamente, investigar nuevas técnicas de procesado digital de señal (DSP, digital signal processing) que puedan ser utilizadas en sistemas de transmisión óptica no-coherentes empleando la modulación por amplitud de pulsos (PAM, pulse-amplitude modulation). Para que una técnica DSP sea interesante en el contexto de una red óptica WDM no-coherente, esta debe mitigar de manera efectiva al menos una de las tres limitaciones principales que afectan a estos sistemas: limitaciones de ancho de banda, limitaciones por dispersión cromática (CD), y el ruido. En esta tesis se proponen y examinan una serie de algoritmos cuyo su rendimiento es analizado mediante simulación y experimentalmente en laboratorio: - Feed-forward equalizer (FFE): este es el esquema de ecualización más común que se emplea principalmente en las transmisiones ópticas no-coherentes de alto régimen binario. Puede compensar grandes limitaciones en el ancho de banda. - Estimación de la secuencia de máxima verosimilitud (MLSE): el MLSE es un detector óptimo y, por lo tanto, proporciona las mejores prestaciones en detección cuando se abordan las limitaciones por CD y de ancho de banda. - Conformación geométrica de la constelación: en los esquemas de modulación de intensidad óptica multinivel, la distancia entre los niveles de amplitud puede ajustarse adecuadamente (de manera que no son equidistantes) a fin de aumentar la tolerancia de la señal frente al ruido. - Conformación probabilística: técnica diseñada específicamente para esquemas de modulación multinivel. Esta técnica ajusta la probabilidad de cada nivel de amplitud de modo que se incrementa la tolerancia al ruido óptico. - Señalización de respuesta parcial (PRS, partial signaling response): este es un enfoque basado en DSP donde una interferencia entre símbolos (ISI, inter-symbol interference) controlada es introducida intencionalmente de tal manera que la señal resultante requiere menos ancho de banda. La técnica PRS puede adaptarse para combatir también el efecto de CD. - Pre-énfasis digital (DPE, digital pre-emphasis): esta técnica consiste en aplicar el inverso de la función de transferencia del sistema a la señal en el transmisor, lo que reduce el impacto de las limitaciones de ancho de banda en el receptor. -… Advisors/Committee Members: Llorente Sáez, Roberto (advisor), Stojanovic, Nebojsa (advisor).

▼ Asymmetric Digital Subscriber Line in its standardized versions G.DMT and G.Lite uses discrete multitone modulation (DMT) for data transmission. Orthogonal Frequency Division Multiplexing (OFDM) is a similar modulation standard for wireless transmission that has been adopted in IEEE 802.11a wireless local area network, Digital Video Broadcasting and HYPERLAN/2. The transmission channel induces inter-symbol (ISI) interference and other noise sources. The traditional DMT or OFDM equalizer is a cascade of a time domain equalizer (TEQ) as a single finite impulse response filter (FIR), a fast Fourier transform (FFT) multicarrier demodulator, and a frequency domain equalizer as a one-tap filter bank. The time domain equalizer shortens the transmission channel impulse response to mitigate ISI. Previous TEQ design methods optimize objective functions not directly tied to system bit rate. I present the equalizer design that maximizes the bit rate of a DMT system at the output of the FFT demodulator. I develop a subchannel Signal-to-Noise Ratio (SNR) model where the desired signal is formed as the circularly convolved data symbol and the channel impulse response at the input of the FFT and noise is the difference between the received and the desired signal. The received signal also includes the near-end crosstalk, additive white Gaussian noise, analog-to-digital converter quantization noise and the digital noise floor due to finite precision arithmetic. Using the subchannel SNR model, I arrive at the optimal time domain per-tone equalizer filter bank (TEQFB) that maximizes a measure of the ADSL system bit rate. I propose a novel receiver architecture that uses TEQFB and a Goertzel filter bank demodulator at the receiver during data transmission. I also present the design of single FIR equalizer that on average achieves more than 99% of the performance of the TEQFB for the tested standard ADSL carrier serving area loops. Simulation results show that the TEQFB and single FIR outperform the bit rate achieved by the minimum mean-squared error design methods, maximum bit rate approach, and minimum ISI design. The TEQFB also outperforms the leastsquares initialized per-tone equalizer (LS PTE) method while the single FIR closely matches LS PTE performance. Advisors/Committee Members: Evans, Brian L.

O canal sem ﬁo tem características de desvanecimento devido ao multipercurso, visto que há reﬂexões e espalhamentos ao longo do caminho percorrido pelo sinal. O desvanecimento é considerado uma das principais causas de degradação do desempenho em um sistema de comunicações móveis, visto que depende fortemente do canal em que se propaga o sinal transmitido. A diversidade de modulação é uma técnica eﬁciente em termos de utilização de banda de frequência, que consiste na rotação da constelação do sinal digital transmitido associado ao entrelaçamento das componentes de modulação em fase e em quadratura da constelação do sinal. O objetivo da diversidade em modulação é mitigar os efeitos do desvanecimento em comunicações sem ﬁo. Esta dissertação aborda o estudo da diversidade de modulação no cenário de múltiplos raios de propagação Osresultadosapresentamsimulaçõesdecenárioscom múltiplos raios, isto é, o sinal é transmitido por múltiplos percursos, cada um associado a um fator de desvanecimento e um atraso aleatórios. São feitas comparações entre as taxas de erros para oito cenários com e sem interferência intersimbólica, de um a seis raios, com e sem linha de visada, para os esquemas de modulação digital 4-PSK e 8-PSK. São apresentadas as comparações entre os resultados de taxas de erros com e sem o uso da técnica de diversidade de modulação, com a intenção de avaliar o ganho desta técnica nestes cenários. Também é feita uma análise para obter o ângulo de rotação ótimo para as constelações mencionadas, considerando diferentes cenários de multipercurso. Para tanto, são empregados os conceitos de esquemas de modulação digital, múltiplos percursos, distribuições de probabilidade, canais de comunicação e técnicas de diversidade.

▼ The design of a single-loop continuous-time ∑∆ modulator (CT∑∆M) with high resolution, wide bandwidth, and low power consumption is very challenging. The multi-stage noise-shaping (MASH) CT∑∆M architecture is identified as an advancement to the single-loop CT∑∆M architecture in order to satisfy the ever stringent requirements of next generation wireless systems. However, it suffers from the problems of quantization noise leakage and non-ideal interstage interfacing which hinder its widespread adoption. To solve these issues, this dissertation proposes a MASH CT∑∆M with on-chip RC time constant calibration circuits, multiple feedforward interstage paths, and a fully integrated noise cancellation filter (NCF). The prototype core modulator architecture is a cascade of two single-loop second- order CT∑∆M stages, each of which consists of an integrator-based active-RC loop filter, current-steering feedback digital-to-analog converters, and a four-bit flash quantizer. On-chip RC time constant calibration circuits and high gain multi-stage operational amplifiers are realized to mitigate quantization noise leakage due to process variation. Multiple feedforward interstage paths are introduced to (i) synthesize a fourth-order noise transfer function with DC zeros, (ii) simplify the design of NCF, and (iii) reduce signal swings at the second-stage integrator outputs. Fully integrated in 40 nm CMOS, the prototype chip achieves 74.4 dB of signal-to-noise and distortion ratio (SNDR), 75.8 dB of signal-to-noise ratio, and 76.8 dB of dynamic range in 50.3 MHz of bandwidth (BW) at 1 GHz of sampling frequency with 43.0 mW of power consumption (P). It does not require external software calibration and possesses minimal out-of-band signal transfer function peaking. The figure-of-merit (FOM), defined as FOM = SNDR + 10 log10(BW/P), is 165.1 dB.

▼ Next generation of wireless communication (5G) devices must achieve higher data rates, lower power consumption and better coverage by making a more efficient use of the RF spectrum and adopting highly exible radio architectures. To meet these requirements, the development of new radio devices will be far more complex and challenging than their predecessors. The future of radio communications have a twofold evolution, being one the low power consumption and the other the adaptability and intelligent use of the available resources. Conventional approaches for the radio physical layer are not capable to cope with the new demand for multi-band, multi-standard radio signals and present an inefficient and expensive solution for simultaneous transmission of multiple and heterogeneous radio signals. Digital radio transmitters have been presented as a solution for a newer and more exible architecture for future radios. All-digital transmitters use a completely digital implementation of the entire radio datapath from the baseband processing to the digital RF up-conversion. This concept bene ts from the use of highly integrated hardware together with a strong radio digitalization, motivated by the exibility and high performance from cognitive and software defi ned radio. However, such devices are still far from a massive deployment in most of communication scenarios due to some limiting factors that hinder their use. This PhD thesis aims to the development of novel radio architectures and ideas based on all-digital transmitters capable of improving the adaptability and use intelligently the available resources for software de ned and cognitive radio systems. The focus of this thesis is on the improvement of some of the common limitations for all-digital transmitters such as power efficiency, bandwidth, noise-shaping and exibility while using efficient and adaptable digital architectures. In the initial part of the thesis a review of the state-of-the-art is presented showing the most common digital transmitter architectures as well as their major bene ts and key limitations. A comparative analysis of such architectures is made considering their power and spectral efficiency, exibility, performance and cost. Following this initial analysis, the work developed on the course of this PhD is presented and discussed. The initial focus is on the improvement of all-digital transmitters bandwidth trough the study and use of parallel processing techniques capable of greatly improve common bandwidth values presented in the state-of-the-art. The presented work has resulted in several publications where FPGA-based architectures use parallel digital processing techniques to improve the system's bandwidth by a factor higher than 10. Other fundamental contribution of this thesis is focused on the pulsedtransmitters coding efficiency. In this section of the thesis, a method is presented showing the reduction of the quantization noise created by low amplitude resolution digital transmitters using… Advisors/Committee Members: Oliveira, Arnaldo Silva Rodrigues de (advisor), Vieira, José Manuel Neto (advisor).

La détection cohérente combinée avec le traitement du signal s’est imposée comme le standard pour les systèmes de communications optiques longue distance à 100 Gb/s (mono-porteuse) et au-delà. Avec l'avènement des convertisseurs numérique-analogique à haute vitesse et haute résolution, la génération de formats de modulation d'ordre supérieure avec filtrage numérique est devenue possible, favorisant l’émergence de transmissions à forte densité spectrale. En outre, la généralisation des liaisons non gérées en dispersion permet une modélisation analytique du canal optique et favorise l'utilisation d’outils puissants de la théorie de l'information et du traitement du signal. En se fondant sur ces outils, de nouveaux formats de modulation à entrelacement temporel dits hybrides et formats multidimensionnels sont étudiés et mise en oeuvre expérimentalement. Leur impact sur les algorithmes de traitement du signal et sur le débit d'information atteignable est analysé en détail. La conception de transpondeurs de prochaine génération à 400 Gb/ s et 1 Tb/s reposant sur des signaux à débit-symbole élevé est également étudiée. Ces systèmes sont intéressants pour réduire le coût par bit en augmentant la capacité émise par transpondeur. L'élaboration d'algorithmes de traitement du signal avancés associés à l’utilisation de composants optoélectroniques à l'état de l'art ont permis la démonstration d’expériences records: d’une part la première transmission mono-porteuse à 400 Gb/s sur une distance transatlantique (pour une efficacité spectrale de 6 b/s/Hz) d’autre part la première transmission à 1 Tb/s basée sur la synthèse en parallèle de plusieurs tranches spectrales (8 b/s/Hz)

Coherent detection in combination with digital signal processing is now the de facto standard for long-haul high capacity optical communications systems operating at 100 Gb/s per channel and beyond. With the advent of high-speed high-resolution digital-to-analog converters, generation of high order modulation formats with digital pulse shaping has become possible allowing the increase of system spectral efficiency. Furthermore, the widespread use of transmission links without in-line dispersion compensation enables elegant analytical optical channel modeling which facilitates the use of powerful tools from information theory and digital signal processing. Relying on these aforementioned tools, the introduction of time-interleaved hybrid modulation formats, multi-dimensional modulation formats, and alternative quadrature amplitude modulation formats is investigated in high-speed optical transmission systems. Their impact on signal processing algorithms and achievable information rate over optical links is studied in detail. Next, the design of next generation transponders based on high symbol rate signals operating at 400 Gb/s and 1 Tb/s is investigated. These systems are attractive to reduce the cost per bit as more capacity can be integrated in a single transponder. Thanks to the development of advanced signal processing algorithms combined with…

▼ Dans le contexte des Réseaux Optiques Passifs (PON), les opérateurs recherchent des solutions innovantes pour augmenter le débit agrégé, nombre d'utilisateurs et portée de la transmission. En plus, des solutions émetteurs-récepteurs à bas coût sont nécessaires. La technique de transmission Orthogonal Frequency Division Multiplexing (OFDM) peut améliorer les performances de la communication en termes de débit agrégé et portée comparé à la modulation classique On-Off Keying (OOK) mono-porteuse. Au même temps, la technologie Photonique sur Silicium permet de réduire le coût par unité des émetteurs-récepteurs, en raison de sa capacité de production en masse et intégration électro-optique. L'OFDM optique a déjà démontré son potentiel avec des composants optiques sur étagère. Par contre, son utilisation avec des émetteurs compatibles avec la technologie Photonique sur Silicium est plus difficile. L'objectif de ce travail est d'étudier les performances d'un lien basé sur des composants Photoniques sur Silicium utilisant la technique de modulation OFDM. Pour atteindre cet objectif, une plateforme de simulation dédiée est développée. Le modulateur-démodulateur OFDM est mise en place, ainsi que des modèles d'émetteurs Photoniques sur Silicium développés pendant la thèse. Ces modèles sont validés expérimentalement avec la caractérisation des composants disponibles au laboratoire. En parallèle, un banc expérimental est construit. Les émetteurs Photoniques sur Silicium sont comparés avec des composants à l'état-de-l' art sur étagère dans un lien OFDM optique. Dans les systèmes en modulation d'intensité et détection directe (IM/DD), une technique d'allocation quasi-optimale de bits et puissance avec de l'OFDM optique est proposée pour maximiser l'efficacité spectrale. Deux types d'émetteurs Photoniques sur Silicium sont considérés : des lasers hybrides III/V-sur-Silicium en modulation directe (expérimentation) et des modulateurs externes comme le Mach-Zehnder (MZM) (simulation) et en anneau-résonant (expérimentation et simulation). Les résultats expérimentaux montrent qu'un débit agrégé de 10Gbps peut être attendu jusqu'à 50km de fibre monomode, compatible avec les exigences de futures générations de PONs. La portée de la transmission (>10Gbps) avec le modulateur en anneau est limitée à 20km, en raison des pertes de couplage élevé en entrée/sortie de la puce. Les simulations montrent que la portée peut atteindre 100km si les pertes sont réduites. Une technique de modulation appelée Single-Side Band (SSB)-OFDM est connu pour améliorer le produit bande-passante-portée de la transmission, en comparaison avec des systèmes IM/DD (Dual-Side Band (DSB)). Par contre, l'émetteur SSB exige plusieurs composants électriques et optiques discrets, augmentant sa complexité. La technologie Photonique sur Silicium permet de un haut niveau d'intégration électro-optique. Pour cette raison, une implémentation spécifique d'un modulateur optique IQ sur Silicium permettant une génération efficace d'un signal SSB-OFDM est étudiée. Les résultats de… Advisors/Committee Members: Tchelnokov, Alexei (thesis director).
