By using Poly(methyl methacrylate) (PMMA) as a host matrix of the materials, we investigate photorefractive property of PMMA-based polymer. The photorefractive index of the materials is experimentally measured by using two-beam coupling method. Because the nonlinear optical molecules, such as phenanthrene quinone (PQ) and azo-dye molecules etc, have been doped with PMMA, the results show that the photorefractive effects are improved evidently. Furthermore we find that the influence of outside electric field on photorefractive property of PMMA-PQ polymer are evidently decreased. The glass transition temperatures of the polymer and the doping amount of chromophore in PMMA are also discussed. Some good results have been obtained.
