| contents | We investigate advanced CMOS-compatible Graphene/Silicon active metasurfaces based on guided-mode resonance filters. The simulated results show a high extinction ratio (>25 dB), narrow linewidth (~1.5 nm @1550 nm), quality factor of Q~1000, and polarization-insensitive operation. By taking advantage of graphene broadband absorption, we present a multispectral operation in the MIR using simple geometrical scaling rules. We further showcase that the same device architecture can be employed for thermo-optic tuning using graphene as an integrated microheater. Our work contributes to the development of advanced broadband silicon-based active metasurfaces for tunable spectral filters and laser mirrors, optical switches, modulators, and sensors. |
