    摘要: A differential input optical modulator, suited for an electrical driver with complementary outputs is provided by the present invention. One embodiment uses an X-cut LiNb03 substrate, with or without a buffer layer, to reduce cost of manufacture in comparison to some known devices that employs a Z-cut LiNbO∩ substrate. These prior art devices require both buffer and charge bleed-off layers. The present invention also includes a quasi-symmetric electrode structure in which the applied fields run parallel to the surface of the substrate.
