Low-Loss Graphene Waveguide Modulator for Mid-Infrared Waves
Graphene waveguide plays an important role in modulating optical signal. But it is hard to make a tradeoff between low propagating loss and high field confinement. Here, we propose a bilayer graphene waveguide in a thin topas film and a high refractive index material-germanium cladded with thin meta...
