Abstract
The photorefractive properties of polymer composites based on poly(N-vinylc arbazole), doped with the sensitizer C-60, the plasticizer butyl benzyl pht halate, and two series of chromophores are presented. The influence of the structure and the oxidation potential of the chromophore on the photorefrac tive properties is discussed. These materials show promise for video-rate o ptical processing applications,since they exhibit fast response times (beam -coupling growth times, tau(g), as small as 60 ms at 50 V/mu m applied fiel d and 200 mW/cm(2) intensity and tau(g) as small as 5 ms at 100 V/mu m and 1 W/cm(2)).
