Active photonic devices incorporating high dielectric constant materials

Abstract

An integrated optical system including a cryostat and a device disposed in the cryostat. The device including an electro-optic switch that includes at least one input port and a first beam splitter. The electro-optic switch including a Mach-Zehnder interferometer coupled to the first beam splitter, wherein the Mach-Zehnder interferometer includes a phase adjustment region including a waveguide core characterized by a first dielectric constant and a waveguide cladding at least partially surrounding the waveguide core and including a second material characterized by a second dielectric constant greater than the first dielectric constant. The electro-optic switch including a second beam splitter coupled to the Mach-Zehnder interferometer; and a set of output ports coupled to the second beam splitter.
