Abstract
A photorefractive device () and method of manufacture are disclosed. The device () comprises a layered structure in which one or more polymer layers () are interposed between a photorefractive material () and at least one transparent electrode layer (). The layered structure is further interposed between a plurality of substrates (). When a bias is applied to the device (), the device () exhibits an increase in signal efficiency of approximately three to four times that of similar, but non-buffered, devices. Concurrently, the device () of the present disclosure utilizes approximately half the biased voltage, advantageously resulting in a longer device lifetime.
