✦ Synopsis

A new photorefractive composite based on a bifunctional methacrylate copolymer with N-methacryloxypropyl-3-(p-nitrophenyl)azo carbazole and N-methacryloxypropyl carbazole as pendant side chains, which has high stability and potential applications, was synthesized. A two-beam coupling gain coefficient of 9.4 cm Ϫ1 and an electrooptic coefficient of 9.3 pm/V were measured at the applied electric field of 92.4 V/m by a typical two-beam coupling experiment and a compensation electrooptic measurement technique.
