Paper Abstract

We have carried out successfully two-wavelength photon-mode optical storage using photochromic diarylethene materials, 1,2-bis(2-methyl-5-(2-(1,3-dioxolane))-thien-3-yl)perfluorocyclopentene (1a) and 1,2-bis(2-methyl-5-(2,2'- dicyano-vinyl)-thien-3-yl)perfluorocyclopentene (2a), as recording medium. Two laser beams of 532 and 780 nm were used in recording and readout simultaneously, and signals with high S/N ratio were obtained. The results showed that the two diarylethenes had responded rapidly upon irradiation of the corresponding wavelength laser. The destruction of the readout and the photochromic properties of the two diarylethenes in PMMA film were also investigated.
