Guided-Wave Acoustooptic and Magnetooptic Devices for Integrated Optic Information Processing.

Abstract

The research objectives of the current program year are focused on the basic interactions and physical mechanisms for guided wave acoustooptic Bragg diffraction from surface acoustic waves in GaA1As optical waveguides and guided-wave magnetooptic diffraction from magnetostatic surface waves in YIG-GGG optical waveguides. To a large degree the objectives have been accomplished. For the first project, very significant progress has been made in the experimental phase. First, a complete liquid phase epitaxy (LPE) system for growth of large size single-mode GaA1As optical waveguides has been established in-house. Second, the RF sputtering system was further improved to deposit good quality zinc oxide (ZnO) films on the top of the GaA1As optical waveguides, and a novel electrode arrangement was facilitated to provide efficient transduction of the SAW. For the first time, a complete facility has been established to fabricate miniaturized acoustooptic Bragg cells in ZnO-GaA1As composite waveguides with the device dimensions as small as 0.2 x 0.5 x 1.0 cm. For the second project, much progress has been made. The theoretical study, firmly identified and established the physical mechanisms for the non-collinear co-planar interaction configuration. Both Faraday and Cotton-Mouton effects are involved in a rather complex manner, in contrast to the collinear interaction in which only the Faraday effect has to be taken into account.
