摘要： 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.

摘要： 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). One or more electrolytes are dispersed into the one or more polymer layers (110). When a bias is applied to the device (100), the device (100) exhibits an increase in signal efficiency compared to a similar device without electrolyte. Both grating decay time and grating response time are greatly reduced by dispersing electrolytes into one or more polymer layers in the photorefractive device. The grating decay time can be adjusted by dispersing different kinds of the electrolytes and/or different concentration of the electrolytes, which can be fitted into all kinds of applications with different requirements for grating response and decay time.
