Design and principles of the multichannel modulator of light created on the basis of photorefractive crystals Bi12GeO20, Bi12SiO20 are resulted in the work. The high gear characteristics of the modulator are achieved at use of a design of male electrodes. The calculation of distribution of electrical fields and induced difference of phases is conducted depending on a structure of male electrodes and thickness of a crystal plane. The modulation and temporary characteristics of the multichannel modulator of light experimentally are investigated.
