Abstract
Applications of photorefractive polymeric composite for holographic data storage medium and phase conjugation mirror were demonstrated. Polymeric material composed of photoconducting carbazole-substituted polysiloxane matrix, 2,4,7-trinitro-9-fluorenone, and 2-{3-[( E)-2-(dibutylamino)-1-ethenyl]-5,5-dimethyl-2-cyclohexeny liden}malononitrile chromophore exhibited a diffraction efficiency of 92% at an electric field of 30 V/μm. Holographic recording, reading, and erasing of single page image were demonstrated using the 100 μm thick polymeric composite. We also demonstrated that the distorted phase of the object beam introduced by a image distorter was successfully restored using a phase conjugation mirror.
