Abstract
The chief requirements for useful photorefractive materials are high sensitivity, high interaction efficiency, high material quality, and high speed (in the case of real- time processing). These are necessary if photorefractive materials will ever find a niche in the image processing market, The consumer needs of optical image processing dictate the use of low-power compact lasers coupled with fast image processing speeds. To fill these requirements, photorefractive quantum well structures and thin films have many of the necessary properties.
