Paper Abstract

In this paper, two-photon bit data storage in azobenzene polymer liquid crystal (PLC) film using low-power continuous wave (CW) laser beam at 532 nm is proposed and demonstrated for the first time, the exposure threshold of the material is below 4 X 106 mw/cm2, and a bit data storage pattern is recorded by two-photon absorption (TPA). The data is easily erasable and rewritable by the light of the same wavelength as the recording light.
