A photorefractive device (100) and method of manufacture are disclosed. The device (100) comprises a layered structure in which one or more polymer layers (110) are interposed between a photorefractive material (106) and at least one transparent electrode layer (104). The layered structure is further interposed between a plurality of substrates (102). When a bias is applied to the device (100), the device (100) exhibits an increase in signal efficiency of approximately three to four times that of similar, but non-buffered, devices. Concurrently, the device (100) of the present disclosure utilizes approximately half the biased voltage, advantageously resulting in a longer device lifetime.
A method for improving the performance of a photorefractive device which contains at least one transparent electrode layer and a photorefractive material, the method comprising interposing one or more polymer layers between the transparent electrode layer and the photorefractive material, wherein the total combined thickness of the one or more polymer layers is from about 2 μm to about 40 μm.
