Photorefractive polymer device with video-rate response time operating at low voltages

Not Accessible

Your library or personal account may give you access

Abstract

The high-voltage bias required for video-rate compatible, efficient operation of a photorefractive polymer composite is reduced from 6–8 to 1.3kV. At this low voltage, the device can hold erasable Bragg holograms with 80% efficiency in addition to having a video-rate response time. The transition of the hologram’s state from thick to thin is analyzed in detail.
