Electro-Refraction Modulation Predictions for Silicon Graphene Waveguides in the 1540–1560 nm Region
We derive analytical approximations for the variation of the effective indices of the fundamental transverse electric (TE) and transverse magnetic (TM) modes with the chemical potential of graphene in three common types of silicon graphene waveguides. In all cases, a third-order polynomial provides...
