Paper Abstract

Optically controlled spatial light modulator was demonstrated as application of photorefractive polymeric material. Since photorefractive composite based on carbazole-substituted polysiloxane matrix (PSX-Cz) has an advantages of stability in phase separation, compared to poly(N-vinyl carbazole) based composite, we can dope almost all kinds of chromophore with the PSX-Cz to prepare a photorefractive composite. Here a chromophore 2-[3-[(E)-2-(piperidino)-1-ethenyl]-5,5-dimethyl-2-cyclohexenyliden] malononitrile (P-IP-DC), with large dipole moment and large polarizability anisotropy was adopted into a photorefractive sample, which showed a high diffraction efficiency of 85 % at an external field of 28 V/μm. Using this photorefractive composite, incoherent image imposed in Xe-lamp light was converted into coherent image in He-Ne laser light by the optically controlled spatial light modulator.
