Abstract
An electro-optic device comprises a substrate of electro-optic material having at least one optical waveguide formed therein subjacent a main surface thereof for propagating an optical mode. A coplanar transmission line is formed on the main surface of the substrate and has at least first and second electrodes spaced apart by an electrode gap that is wider than the first electrode. The center of the waveguide is within the electrode gap and closer to the first electrode than the second electrode.
