Abstract (sommario):
The integrated reflective semiconductor optical amplifier (RSOA) and electro-absorption modulator (EAM) is viewed as an appealing solution to the colorless transmitter on the optical network unit (ONU) side of wavelength-division multiplexed (WDM) passive optical networks (PONs), for its broad modulation bandwidth and high optical gain. However, the conventional RSOA–EAM usually exhibits a poor upstream signal eye-diagram because it can hardly simultaneously saturate the downstream signal and boost the upstream signal as required. By exploiting the polarization-depended RSOA gain, we propose a polarization-discriminated RSOA–EAM to improve the quality of the upstream signal eye-diagram. In this device, the transverse electric polarized downstream signal is saturated by the high gain in the RSOA active region made of compressively strained multiple quantum wells, whereas the upstream signal is linearly amplified after polarization rotation. We find that, as the quality of the upstream signal eye-diagram improves with an increased polarization rotation angle, its power drops, which indicates that there exists an optimized rotation angle to reach a compromise between the upstream signal integrity and power. Simulation results show that the dynamic extinction ratio and output power of the upstream signal can reach 8.3 dB and 11 dBm, respectively, through the proposed device with its rotation angle set at an optimum value (80°), which exceeds the specification (6 dB and 4 dBm) of the upstream transmitter as required by the next-generation PON stage two. The quality of the upstream signal eye-diagram measured in Q-factor is improved by 10 dB compared to the conventional RSOA–EAM design without polarization rotation introduced.

Abstract (sommario):
Dans cette thèse, nous étudions des modulateurs à électroabsorption (EAM) en réflexion, intégrés de manière monolithique sur InP avec des amplificateurs optiques à semi-conducteurs (SOA), pour réaliser des transmetteurs indépendants de la longueur d'onde (achromatiques). Ces composants sont conçus pour des applications dans les réseaux d'accès, qui nécessitent un déploiement dense de transmetteurs-récepteurs optiques à faible coût. Les composants sont basés sur des zones actives à multi-puits quantiques GaInAsP/InP (MQW) et ont été fabriqués par un technologie à guides d’onde enterrés (semi-insulating buried hetero-structure, SIBH). Une approche d’intégration longitudinale type ‘bout-à-bout’ (butt-joint) a été adoptée pour combiner les zones actives MQW des différentes fonctions de bases (build-ing blocks, BBs) sur une même puce. Nous analysons des circuits, basés sur plusieurs combinaisons des BBs, avec trois longueurs de modulateur différentes (80, 100 et 150 μm). Nous effectuons une analyse complète des performances statiques et dynamiques des composants réalisés. Pour les SOA, nous obtenons un gain >17 dB, avec un facteur de bruit d'environ 4 dB. Pour les EAM, nous atteignons une bande passante de modulation >33 GHz et un taux d'extinction dynamique jusqu'à 15 dB. Les EAM présentent un chirp nul, pour des tensions de polarisation inverse dans la plage comprise entre −1,2 V et −1,5 V, en fonction de la longueur d'onde de fonctionnement. Pour les composants fonctionnants dans la bande C, nous démontrons des transmissions achromatiques à 25 Gb/s, sur une plage spectrale de 15 nm, jusqu'à 16 km, en utilisant le format de modulation non-return-to-zero (NRZ). Avec les composants fonctionnant dans la bande O, nous montrons des transmissions jusqu'à 50 Gb/s NRZ, ainsi que des transmissions PAM-4 sans égalisation. Enfin, nous effectuons une transmission multicanal bande V/IFoF de 10 Gb/s, atteignant une amplitude de vecteur d'erreur <11%
In this thesis, we study reflective electroabsorption modulators (EAMs) monolithically integrated with semiconductor optical amplifiers (SOAs) to realize wavelength-independent (colorless) transmitters for low-cost access network applications that require dense deployment of optical transceivers. The devices are based on GaInAsP/InP multiple quantum-wells (MQWs), leveraging semi-insulating buried heterostructure (SI-BH) waveguide and butt-joint integration technologies. We analyze different design tradeoffs by considering three modulator lengths (80, 100 and 150 μm). After fabrication, we perform a complete performance analysis of our components in both static and dynamic modes. We obtain >17 dB SOA gain with a noise figure of about 4 dB. For the EAM, we achieve >33 GHz modulation bandwidth and up to 15 dB dynamic extinction ratio. The EAMs exhibit zero-chirp for reverse bias voltages in the range between −1.2 V and −1.5 V, depending on the operating wavelength. For C-band components, we demonstrate up to 16 km colorless trans-mission, over 15 nm, at 25 Gb/s using non-return-to-zero (NRZ) modulation format. With components working in the O-band, we per-form up to 50 Gb/s NRZ as well as PAM-4 transmissions without equalization. Finally, we perform a 10 Gb/s multi-channel V-band/IFoF transmission, achieving <11% error vector magnitude

Abstract (sommario):
Nas topologias de redes WDM-PON (Wavelength Division Multiplexed Passive Optical Network) baseadas em transmissores colorless, isto é, transmissores que possam operar em uma grande gama de comprimentos de onda, que empreguem técnica de auto-alimentação e reuso de comprimento de onda, tem despertado grande interesse devido a sua comprovada eficiência, granularidade e custo reduzido em relação às alternativas. Entretanto, o alcance destas redes é limitado pelo emprego de remodulação, devido a dependência existente com a qualidade dos sinais a serem remodulados. Neste cenário, mantendo-se uma melhor relação custo-benefício, taxas de operação típicas são da ordem de 1,25, e 2,5 Gb/s (20 quilômetros). Neste trabalho é investigada uma nova topologia que combina as técnicas de auto-alimentação e reuso de comprimento de onda, bem como, utiliza um circuito de dupla cavidade óptica, possibilitando um reforço no apagamento óptico e manutenção do estado da polarização no percurso de recirculação da cavidade externa, objetivando uma melhora na qualidade dos sinais a serem remodulados, possibilitando altas taxas de transmissão e um maior alcance da rede. Nesta topologia, amplificadores ópticos semicondutores refletivos são utilizados como transmissores colorless, por meio da emissão espontânea amplificada, garantido assim uma redução no custo da rede óptica de acesso. Como metodologia adotada, inicialmente foram realizadas caracterizações ópticas no ambiente de simulação, validação da palheta configurada no simulador com resultados experimentais e avaliações da topologia em taxas simétricas de 1,25 Gb/s. Ademais, são conduzidas análises comparativas entre a topologia proposta frente a topologias disponíveis na literatura no estado da arte. Com os resultados obtidos, acredita-se que essa proposta atende aos requisitos de capacidade agregada e custo reduzido, podendo alcançar taxas de transmissão de até 10 Gb/s utilizando transmissores de baixa complexidade, características essenciais para impulsionar a implementação de redes de acesso óptico.
WDM-PON topologies based on colorless transmitters employing self-seeding and wavelength-reuse techniques have attracted a great deal of interest because of its well known efficiency, granularity and reduced cost, when compared to other alternatives in the literature. Nevertheless, the network reach is limited by the use of remodulation scheme. Maintaining an adequate cost-benefit relation requires typical operating rates of the order of 1.25 Gb/s to 2.5 Gb/s over 20 km of SSMF. In the above framework, we investigate a new topology which combines self-seeding and wavelength-reuse techniques, but also employs a scheme to reinforce the data erasure in the optical carrier, simultaneously providing state of polarization (SOP) maintenance in the external cavity recirculation path. The proposed configuration improves the quality of the signals to be remodulated, thus allowing high rate and broader reach. Specifically, in our work, reflective semiconductor optical amplifiers are employed as colorless transmitters, by using their own amplified spontaneous emission as a seed to provide the optical carrier. Optical analysis were performed in a simulation environment, including self-seeding layout validation by comparison to experimental results at the symmetric transmission rate of 1.25 Gb/s. Next, comparative analysis are conducted between the topology proposed in this work and topologies in the state of the art, found in the literature. According to the results, we believed that the proposal meets the requirements of aggregate capacity and reduced cost, being able to reach transmission rates of up to 10 Gb/s by using transmitters of low complexity, essential features to drive optical access networks implementation.
