Abstract
We present the results of chemical development and optical investigation of the extraordinarily large photorefractive effect in the new polymer nanocomposites. The composites are composed of poly(ethynylene)arylenesilanes as optical chromophores, poly(9-vinylcarbazole) as photoconductor, N- ethylcarbazole and phenyltrimethoxysilane as plasticizer, and C70 and C60 fullerenes as charge generators. The magnitude of the change in photorefractive index and its origin, and temporal behavior were studied at 633 nm by a variety of nonlinear optical techniques, including nonlinear lens method, four-wave mixing and two-beam coupling. The relaxation time of the photorefractive index changed in a range from a few seconds to tens of minutes at changing beam intensity.
