    摘要： A photorefractive device (100) and methods of its manufacture are disclosed. The photorefractive device (100) comprises one or more transparent electrode layers (104), one or more sol-gel buffer layers (113), one or more polymer buffer layers (105), and a photorefractive layer (106). The one or more sol-gel buffer layer (113) is interposed between the one or more polymer buffer layer (105) and the one or more transparent electrode layer (104). When a bias voltage is applied to the device (100), the device (100) exhibits improvement in electric breakdown strength compared to a similar device without the one or more dielectric sol-gel buffer layers (113). The device (100) can operate at high bias levels with quick rising and decay times and shows higher grating performance under single nanosecond pulse recording conditions.

    摘要： Described herein are optical devices comprising a photorefractive layer and at least two inert layers, such that the photorefractive layer is sandwiched between the two inert layers. The photorefractive layer may include a photorefractive composition that is photorefractive upon irradiation by a laser beam. In some embodiments, the photorefractive composition is formulated such that a grating that is irradiated into the photorefractive composition can be read out of the photorefractive composition without applying an external bias voltage. Furthermore, a grating that is written into the composition may be controlled using thermal treatment.
