Photorefractivity of Polymer-Stabilized Ferroelectric Liquid Crystal Materials Containing Photoconductive Polymers

Abstract

The photorefractivity of polymer-stabilized ferroelectric liquid crystal (PS-FLC) using photoconductive monomer was investigated. The PS-FLC materials exhibited monostable and bistable electrooptic effect. The photorefractivity of PS-FLC material was investigated by two-beam coupling experiments. While the monostable material showed stable photorefractivity, the bistable one showed very instable photorefractivity.
