Abstract

Highly efficient photorefractive polymer composites based on the photoconductor poly(N-vinylcarbazole) and azo dyes as second-order nonlinear optical chromophores, are presented. The photorefractive properties are studied by means of four-wave mixing and two-beam coupling experiments. The photoconducting and electro-optic properties are investigated independently and compared to existing models. The moderate electro-optic properties indicate that other contributions such as birefringence are responsible for the high diffraction efficiencies measured in these samples.
