Abstract:
An electro-optic modulator for use in an optical communication system having an optical signal transiting therethrough, the modulator comprising:an electro-optic substrate having an electro-optic axis oriented parallel to an upper surface of the substrate;an optical waveguide adapted to receive the optical signal and formed in the upper surface of said substrate, said optical waveguide having first and second legs spaced from one another;first and second input electrodes formed on said substrate upper surface and adapted to receive a modulation signal, with each of said input electrodes configured to be in electro-optic communication with a corresponding one of said optical waveguide legs but substantially misregistered therewith;first and second ground electrodes formed on said substrate upper surface spaced from a respective one of said input electrodes and configured to be in electro-optic communication with a corresponding one of said optical waveguide legs but substantially misregistered therewith; andwherein said first input electrode is configured as a center electrode relative to said optical waveguide legs and said second input electrode is configured as an exterior electrode relative to said optical waveguide legs.
