摘要：

We report observation of the photorefractive effect in functionalized polymer-dispersed liquid crystals. The photoconductive properties are provided by the polymer matrix, and the field-dependent refractive-index changes are generated by the dispersed nematic liquid-crystal droplets. and a high refractive-index modulation amplitude (Delta n = 2 x 10(-3)) are obtained in 53-mu m-thick samples with an applied field of 22 V/mu m.
