Abstract

An optical switch comprises a substrate, first and second optical waveguide, and first and second conducting elements. The first optical waveguide is coupled to the substrate. The first conducting element is coupled to the first optical waveguide. The second optical waveguide is coupled to the substrate. The second conducting element is coupled to the second optical waveguide. In operation, a first electrical bias applied between the first and second conducting elements causes the first optical waveguide to not optically couple to the second optical waveguide. Further in operation, a second electric bias applied between the first and second conducting elements causes the first optical waveguide to optically couple to the second optical waveguide.
