Significantly High Modulation Efficiency of Compact Graphene Modulator Based on Silicon Waveguide

Abstract We theoretically and experimentally demonstrate a significantly large modulation efficiency of a compact graphene modulator based on a silicon waveguide using the electro refractive effect of graphene. The modulation modes of electro-absorption and electro-refractive can be switched with di...
