ABSTRACT:
An apparatus and method is disclosed for providing an optical waveguide that is placed in the same plane as the electrodes, thereby creating a more efficient electro optic interaction that requires less voltage to induce the desired effects on the waveguide. In addition, a superstrate is used to cover the waveguide having an index of refraction slightly less than the index of refraction of the waveguide which reduces the scattering loss inherent in the waveguide.
