Abstract

Polymeric photorefractive materials exhibit two attractive features, the large refractive index modulation (up to the order of $10^{-2}$) and the optical erasabilility of recorded holographic information. These advantages make the organic photorefractive materials to become candidates for optical data processing, e.g., pattern recognition and fingerprint verification. In this work, we demonstrate optically controlled SLMs using photorefractive composite. An incoherent image imposed in Xe-lamp light was converted into a coherent image.
