Paper Abstract

A new unsymmetrical photochromic diarylethene 1a is synthesized, and the photochromic properties of it are also investigated. The compound exhibits good photochromism with UV/visible light irradiation. Compound 1a in polymethyl methacrylate (PMMA) film changes color upon 313-nm light irradiation from colorless to blue, in which the absorption maximum is observed at 587 nm. Photon-mode polarization multiplexing holographic optical recording is performed successfully using this compound as a recording medium. In the diarylethene 1b/PMMA film, polarization multiplexing hologram recording and retrieval, and a combination with the angular multiplexing scheme, are demonstrated systematically. The results indicate that recording capacity can be significantly improved with the combined method of polarization and angular multiplexing holographic recording.
