A novel bi-functional photorefractive acrylate polymer with pendant carbazolyl groups and azo derivatives as side chains was synthesized. Photorefractive experiments showed a high twobeam coupling gain coefficient of 93 cm-1. diffraction efficiency of 12% and electro-optic coefficient of 26 pm/V were obtained.
