Abstract

See full text

An optical switch structure includes at least one optical input port and at least one optical output port. The optical switch structure also includes an optical waveguide structure including a waveguide core and a waveguide cladding The optical waveguide structure is optically coupled to the at least one optical input port and the at least one optical output port. The waveguide core includes a first material characterized by a first index of refraction and a first electro-optic coefficient and the waveguide cladding includes a second material characterized by a second index of refraction less than the first index of refraction and a second electro-optic coefficient greater than the first electro-optic coefficient.
