Integrated Acoustooptic Device Modules for Optical Information Processing.

摘要

General objectives of this research are conception, experimentation and realization of new and novel guided-wave AO device modules in LiNbO3 and GaAs with applications to wideband multichannel optical information processing, and study of relevant physical mechanisms. This report presents the major accomplishments that were made in the last program year. These include: 1) Realization of single-mode TIPE microlenses and lens arrays in LiNbO3 waveguide and high-packing density multichannel integrated optic modules; 2) In-depth analysis on guided-wave acoustooptic bragg diffraction in ZnO-GaAs composite waveguides; 3) Realization of high-performance GaAs guided-wave acoustooptic Bragg Cells at GHz frequencies; and 4) Formation of microlenses and lens array in GaAs waveguide using ion milling.
