Abstract
A fundamentally new model of an optical switch with decentralized control is proposed. The advantages of the proposed switch are the absence of optoelectronic conversion of the information signal and the possibility of constructing scalable circuits of low complexity. The switch circuit includes the following main elements: electrically controlled switch elements based on lithium niobate, Bragg filters, optical valves, focusing systems, a control lens system, and a local system for generating control signals. The calculation of the optical devices of the switch shows the possibility of its implementation and operation in the range of 1310-1460 nm for transmitting control signals and 1550 nm for the information signal to ensure interaction between data center devices.
