Abstract

A polymer-stabilized liquid crystal (PSCL) as a new type of organic photorefractive material has been prepared and characterized. It is shown that PSLCs are capable of forming photorefractive gratings that operate in the thick grating regime. Polymer stabilization alters the charge transport and trapping characteristics of LCs, resulting in longer lived gratings, while maintaining the advantages of high orientational birefringence within LCs. Moreover, very low applied electric fields and low optical intensities are required to create large photorefractive effects in these materials.
