Efficiency of Reversible Optical Storage in Azo Polymers

Abstract

Optical information can be stored, erased or overwritten on polymer thin films using polarized light. The information is in the power probe beam. We have measured the efficiency of the writing beam in a number of polymer and copolymer films containing azobenzene dyes as side groups. In this paper we compare the results amongst the polymers have synthesized. Preliminary results indicate that copolymers may be optimized to allow for the preparation of efficient thick films for erasable optical recording.
