A Model of an Optical Switch with Time-Frequency Division of Signal and Decentralized Control

A fundamentally new model of an optical switch with decentralized control is proposed. The advantage of the optical switch is the ability to build scalable circuits of low complexity without optoelectronic conversion of the information signal. The main elements of the switch circuit are electrically controlled keys 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 showed the possibility of its implementation and operation in the ranges of 1310–1460 nm for transmitting control signals and 1550 nm for an information signal that ensures the interaction of data center devices.
