Abstract: A method is provided for operating one or more one solid-state electro-optic device to provide an electrically switching shutter. The method includes forming an alternating stack of first semiconductor layers having a first dopant and second semiconductor layers having a second dopant to form at least one superlattice semiconductor device. The method further includes applying to the at least one superlattice semiconductor device a first voltage to induce a transparent state of the alternating stack such that light is transmitted through the alternating stack, and applying to the at least one superlattice semiconductor device a second voltage different from the first voltage to induce an opaque state of the alternating stack such that light is inhibited from passing through the alternating stack.

Abstract: A doubly resonant electro-optic converter is provided. An optical resonator and a microwave resonator are disposed such that fields from the two resonators can interact in an electro-optic active medium. The optical resonator is a planar photonic crystal optical resonator, and the microwave resonator is at least partially superconducting in operation. The active medium has a second order nonlinearity capable of generating a sum frequency signal and/or a difference frequency signal from the optical and microwave fields. The resulting structure has both quantum and classical applications.
