Paper Abstract

Electro-optical response of the polymer dispersed liquid crystal films was investigated. The best results obtained were contrast of 400, switch on times > 0.4 ms, off time > 20 ms, threshold voltage 5 V. Combination of such films with thin photoconducting polymer layers permitted us to get optically addressed light valves. Contrast of 35, switch on and off times > 0.4 ms and > 80 ms accordingly for 10-5 Jcm-2 exposition and controlled voltage 100 V were obtained in such modulators for nanosecond pulse writing regime.
