Paper Abstract

An experimental studying of adaptive processing a single-fiber multimode interferometer's signal by means of a photorefractive crystal is presented. Opportunity of developing an adaptive processing system on the base of two photorefractive effects (polarization self-modulation and self-diffraction) is investigated and discussed. A simple mathematical model of a space-charge field forming in the photorefractive crystal under influence of an alternating optical field is considered. Frequency response of the self-diffraction and the polarization self-modulation effects in the photorefractive crystal is calculated on the base of this model.
