Abstract
Accordingly, a preferred embodiment of the present invention comprises an electro-optical device having an optical waveguide that includes two optical pathways, wherein the optical waveguide is embedded within the substrate. A bias electrode layer is formed on the surface of the substrate. A buffer layer is formed on at least a portion of the bias electrode layer and the surface of the substrate. An RF electrode layer is formed on the buffer layer. A bias-tee electrically couples the bias electrode layer and the RF electrode layer.
