Abstract

Photorefractive materials have many potential photonic applications, including dynamic holographic storage and image processing. Recently, the new class of photorefractive polymers has emerged, offering wide structural flexibility, easy processability, and low cost. Progress in this field has led to nearly 100% diffraction efficiency for the readout of a hologram stored in the material and to extremely large net gain coefficients of more than 200 cm^-1. These excellent properties result from refractive index modulations as large as (Delta) n approximately equals 10^-2 which could be generated in these materials with low- power lasers, such as HeNe laser or laser diodes.
