Advanced Guided Wave Electro-Optical Switches

Abstract

Efforts have concentrated on the use of LiTa03 which is emerging as a superior alternative to the more commonly used LiNb03 because of its higher immunity to optical damage. The progress made has resulted in the establishment of vapor diffusion technique for making low loss optical waveguides and its extension for making low loss waveguides by thermal diffusion below Curie temperature that support both TE and TM modes; the development of polarization independent guided-wave electrooptic switches; and the realization of lowest propagation loss ridge waveguides using the RIE process. Progress has also been made on the use of SBN:60. Specifically, a method for producing rib structures has been devised and high index optical waveguides have been obtained. (RH)
