Both the photorefractive (PR) and holographic characteristics of 3-amino-9-ethyl carbazole (AEC)/dispersed orange 3 (DO3)/diglycidyl 1,2 cyclohexanedicarboxylate (DCD) main chain copolymer with the carbazole and the azo chromophore incorporated in a transverse way were investigated without external applied electric field. The recorded pattern exhibited good fringe contrast, the resolution of the recorded hologram was about 20 μm. Problems such as dopant aggregation, fanning, and image distortion was not found in the system.
