FIELD: physics.
SUBSTANCE: controlled optical multiplexer includes a multiple-step structure of filters having elements for controlled adjustment of transfer constants. The optical filters used are asymmetrical Mach-Zehnder interferometres: single-stage and/or two-stage, and/or multistage. Electro-optical or thermo-optical phase-shift devices serve for controlled adjustment of transfer constants of the optical filters. The multiplexer can be made on integrated-optical technology in form of a monolithic solid-state device.
EFFECT: controlled multiplexing of channels in the fibre optic communication system with wavelength-division multiplexing of channels, whose optical frequencies can be adjusted for constant spectral interval neighbouring channels Δν.
