Abstract

The invention relates to the field of data processing and communications and can be used for transmitting, receiving and redistributing data signals in switching and encoding and decoding devices in telecommunication systems, communication systems and data processing systems. Essence of the invention: in the multi-channel switch, which optically connects any given optical input channel with any given optical output channel, the bitwise optical connection of the channels is organized in n stages, where n=lg2N is the number of bits, and the connections are carried out in parallel in each bit. At each stage, an operation is performed to double the number of optical channels and an operation is performed to gather the channels, wherein the gathering of the channels is optically controlled as a result of the photorefractive properties of the material of the optical channels. A multi-channel switch is proposed which comprises an active element made from a photorefractive material with waveguide channels, the switching circuit is a cascaded and branching circuit with parallel connection of the optical input and output channels in each cascade, the connection addresses are set with the aid of bars of optical modulators, the number of channels is doubled, and signals are transferred from channel to channel by feeding optical signals of a given configuration to the photorefractive waveguides.
