Abstract ： We describe a PVK-based photorefractive polymer composite doped with disperse red 1, poly-butylacrylate and TNF. By the two-beam coupling experiment, We investigate its photorefractive properties as well as the dynamic process of the index gratings in the sample. We observe the photorefractive effect in the absence of an applied external electric field. The two-beam coupling gain coefficient was measured to reach as higher as 140 cm-1 in the absence of an external applied electric field and a value of 470cm-1 at a poling dc electric field of 25V/μm.
