Photorefractive Tungsten Bronze Crystals for Optical Computing

Abstract

We have identified and grown new photorefractive tungsten bronze BSTN and BSKNN single crystals for optical computing applications. These crystals exhibit faster response times than the current best SBN:60 with comparable doping concentrations. At Caltech, holographic fixation has been demonstrated in Rh and Cr-doped SBN:75 single crystals. Because of such features, various applications in the areas of data storage, optical pattern recognition and optical computing are emerging for these tungsten bronze crystals.
