Infrared-Sensitive Photorefractive Polymer Composite Devices

Abstract

The main goal of the effort was to develop high performing photorefractive (PR) polymer composites working at 1 micrometer by one photon photorefractivity and two photon photorefractive devices operating at 1.5 micrometers. The utilization of these photorefractive devices for beam cleanup and reconstruction of aberrated images was also an important objective of the effort. We have accomplished these goals by developing highly efficient one photon sensitive photorefractive devices operating at about 1 micrometer with high diffraction efficiency, near video rate response time and high two beam coupling gain. This is the first time demonstration of an all-organic photorefractive material beyond 830 nanometers and the results are the best among any near-infrared photorefractive materials under similar experimental conditions.
