Abstract
Methods, systems, and devices are disclosed for implementing electro-optical modulators in which a resonating cavity structure is coupled to a transmission waveguide. In one example, the resonating structure includes a ring resonator whose coupling strength is controlled via an electrical control signal. The ring resonator is made of a capacitor comprising monolayer graphene sheets separated by a thick layer of dielectric material.
