Abstract:

The research on graphene/silicon-based hetero-integrated photonic devices has made great progress in recent years. The graphene/silicon-based heterogeneous integrated devices have shown excellent performance such as ultra-large bandwidth and ultra-low power consumption thanks to the unique physical properties of graphene, such as ultra-high carrier mobility and ultra-high nonlinear coefficient. In this work, we reviewed the typical graphene/silicon-based heterogeneous integrated devices reported in recent years, including graphene/silicon-based electro-optical modulators, graphene/silicon-based thermo-optical modulators and graphene/silicon-based photodetectors, briefly described their principles and properties, and made a prospect for their future applications and development.
