Abstract

An integrated-optic parallel directional coupler waveguide modulator is the subject of this paper. The device consists of two directional coupler modulators in parallel so that a single laser can be used as a source. Advantages of one laser source are to minimize a relative frequency drift difference and allow for high speed communications on separate channels. Applications include television and videophone where audio and video signals can be transmitted simultaneously. A feedback phase shift noise reduction scheme will be investigated for high speed information flow with high fidelity and high linearity. As the result, the parallel modulation technique approaches transparent transmission which will increase the dynamic range and minimize signal distortions.
