Non-linear optical characterization of polymer dye composites and their characterization as holographic recording media

摘要

In the past few years there has been considerable interest in the development of photorefractive polymeric materials with possible applications in image processing and reversible dynamic holographic storage [1,2]. These materials have many advantages over inorganic photorefractive crystals in applications of high volume information storage and data processing because of their large optical non-linearities, low dielectric constant, low cost and ease of fabrication [3].
