1 November 1996 Use of high-<beta-mu> nonlinear optical chromophores in photorefractive polymers

We report on the first use of high-(Beta) micrometers nonlinear- optical chromophores in photorefractive polymer composites based on poly(N-vinylcarbazole). We demonstrate that the photorefractive effect in these materials originates mostly from the electrooptic effect whereas in high-performance materials known to date the photorefractive effect mostly originates from an orientational birefringence resulting from a nonuniform orientation of the electrooptically active chromophores.
