New materials for advanced silicon photonics

It is clear that silicon photonics requires a directly integrated laser source using wafer- scale technologies, and an efficient modulator without any coupling between amplitude and phase modulation to implement low power and high speed integrated transceivers. To achieve these targets, an increasing amount of research is geared towards the integration of novel materials and the development of new integration methods on the silicon photonics platform. This presentation will give a review of our work in this domain, covering novel methods for III-V integration, novel materials for pure phase modulation (ferro-electrics, 2D-materials) and novel materials focusing on pure amplitude modulation (Ge, SiGe, Graphene).
