A new class of photorefractive (PR) composite based on a fully functionalized polymer with high phase-stability is reported. The polymer containing nonlinear optical (NLO) chromophore and charge-transporting carbazole moieties is synthesized by a polymer analogous reaction. The polymer is doped with plasticizer, NLO dye and sensitizer to fabricate the PR composite. The NLO dye is the same as the NLO chromophore moiety in the polymer side chain. PR performance of the composite is evaluated by degenerated four wave mixing and two-beam coupling measurements. Diffraction efficiency of 30% at relatively low applied electric field of 45 Vμm-1 is achieved. Despite a high concentration of NLO dye, the composites show good stability for a long period without phase separation.
