Design of graphene-based polarization-insensitive optical modulator
By exploiting the electroabsorption effect of graphene, we present a graphene-based polarization-insensitive optical modulator. The waveguide structure consists of a silica substrate, high-index silicon strip waveguide, Si3N4 dielectric spacer, two graphene layers, and two metal electrodes. The modu...
