Hybrid III-V on silicon lasers for optical communications

Abstract : Photonic integration reduces the size and energy consumption of fiber optic communication systems compared to systems assembled from discrete components. This technology has recently attracted a great interest with the progress of integration on InP and the development of silicon photonics. The latter challenges the integration platform on InP as high-performance and low-cost components can be manufactured in foundries originally developed for microelectronics. Lasers are one of the main parts of transceivers for optical communications. With their integration on the silicon platform, transceivers that include the critical functions of light emission, modulation and detection on the same chip can be made. In the heterogeneous integration platform, components are manufactured in high volumes: several tens or even hundreds of components are produced per wafer. In this thesis, I studied theoretically and experimentally the properties of tunable lasers based on silicon ring resonators, directly modulated distributed feedback lasers and low noise high-quality factor lasers
