Popis: Employing all-optical poling technique, we propose a novel method for optical storage based on the mechanism of orientational hole burning and photoinduced molecular reorientation of azobenzene. Recording of an optical binary image was experimentally demonstrated. The recorded information can be stored for a long time and also can be erased rapidly with a circularly polarized light. Furthermore, wavelength conversion of optical image is obtainable using such method. The storage characteristics of two different polymer systems, azo-doped poly(methyl methacrylate) (PMMA) and azo-functionalized polyimide (PI), were investigated and compared.
