Contribution à l'étude de nouvelles technologies de co-packaging et de co-design appliquées à la réalisation de modules photorécepteurs pour les systèmes de télécommunications de prochaine génération

Abstract : This thesis falls within the scope of high-speed short-reach optical communication where the growing need in data transfer forces the current architectures to evolve as quickly. Acces network and data-center components and subsystems must follow this growth, especially on the photoreceiver side. 40 Gb{s and beyond high-speed communications are limited by the current photoreceiver architecture, which, due to the integration of both of its main functions (photodetection[PD]/amplification[TIA]), limits the maximum achievable bandwitdh. In order to reduce the amount of components and price caused by multi-architectures, photoreceivers bandwidth must be increased. Two solutions are proposed so that the photoreceiver performances can be optimized : A co-packaging approach in which both main functions of the photoreceiver are considered as black boxes to which must be added an external circuit allowing to increase the bandwidth, and a co-design approach in which a new transimpedance amplifier (TIA) is designed, integrating a pre-equalizing function based on the photodiode characteristics, allowing an enhancement of the photoreceiver bandwitdh.
