Abstract
The present invention provides an electro-optic modulator and an optical communication system in which a wider signal electrode may be used without affecting the characteristic impedance of the device or the efficiency of the optical modulation. In embodiments of the invention, asymmetric coplanar electrodes are provided such that the gap between the signal electrode and one reference electrode may be optimized for the optical waveguide and the semiconductor section surrounding it, and the gap between the signal electrode and the other reference electrode may be optimized for a particular characteristic impedance.
