Title

Thermodiffusive photorefractivity in liquid crystals

Abstract

A breakthrough in the search for photorefractive materials occurred with the prediction and discovery of photorefractive liquid crystals (LC). Photorefractive LC solves two key problems: first, the voltage necessary to apply to the photorefractive material for realization of wave mixing is reduced from kilovolts to volts; and second, the modulation of the refractive index of the material can be as large as 0.2. The difference between the diffusion constants D+ and D- of photogenerated positive and negative ions is the reason for charge separation and space charge formation in the photoconductive LC.
