Abstract

We propose and investigate tunable CMOS compatible Graphene/Si guided-mode resonance active 1D and 2D filters based on electro and thermo-optic effects at teilecom wavelengths. The elecro-optic effect is achieved by variation in the graphene doping by electrostatic gating, and the thermo-optic effect utilizes graphene as a thermal heater. The proposed filters offer narrow resonances of 1.4 nm, a high extinction ratio of 20 dB and 30 dB for 1D and 2D gratings respectively and thermal efficiency of 0.056 nm/K.
