Abstract: The optical tungsten bronze BSTN and BSKNN single crystals were investigated for photorefractive and guided wave optical applications with considerable success. These materials have both high optical figure of merit and low dark conductivity, making them potentially important for pattern recognition and 3-D memory applications. Undoped crystals are advantageous for electrooptic devices such as guided wave for telecommunication and signal processing. Under this effort, advances were made in growth of large size (4 cm diameter) BSTN and BSKNN crystals with possibility for large scale manufacturing. Also, investigations of guided wave structures were carried out, which showed that the operating voltage and size can be much reduced compared to LiNbO3.
