摘要The integration of graphene with photonic integrated circuits (PICs) has attracted tremendous attention in recent years. In this waveguide configuration, the optical mode of the propagating light in the waveguide couples through its evanescent field to the top-covered graphene layer, leading to the enhanced graphene-light interaction, which enables many applications in optoelectronics, nonlinear optics and sensing. In this presentation, we will review our progress on hybrid integration of graphene with silicon photonics.

We develop several CMOS-compatible platforms based on chemical vapor deposited (CVD) graphene-integrated silicon photonic devices, namely, graphene-on-silicon-on-insulator (SOI) suspended membrane waveguides1, graphene-on-silicon-on-sapphire (SOS) waveguides2, graphene-on-silicon nitride (Si3N4) waveguides3. Based on these platforms, we investigate the enhancement of the graphene-light interaction by using different silicon photonic devices, such as two-polarization mode coupled waveguides1, microring resonators3 and slot waveguides4. Furthermore, we demonstrate high-responsivity waveguide-integrated CVD graphene photodetectors in the telecommunication band based on graphene-on-Si3N4 waveguides5 and graphene-on-SOI slot waveguides6. In addition, we propose theoretical designs of graphene-based waveguide-integrated optoelectronic modulators and gas sensors.
