Abstract:

This report focused on the investigation of the basic properties of novel depletion edge translation DET waveguide phase modulators oriented in the plane of the substrate. Devices based upon this concept have now provided record levels of phase shifting efficiency, and theoretical calculations have indicated a significant potential for still further improvements in this area. The in plane geometry maximizes the interaction between applied fields and the propagating wave by maximizing the optical energy density, the applied fields and providing the necessary interaction length. In this report we review the progress in three separate areas 1 theory and design of DET devices 2 improvements in fabrication technology and 3 experimental device measurements.
