OPTICAL SWITCHING DEVICE, REDIRECTION METHOD, RECONFIGURABLE OPTICAL INPUT/OUTPUT MULTIPLEXER AND SYSTEM Russian patent published in 2025 - IPC G02B6/293 H04J14/02 

FIELD: physics.

SUBSTANCE: group of inventions, which discloses an optical switching device, a redirection method, a reconfigurable optical input/output multiplexer and a system, is intended to improve filtering bandwidth. Optical switching device includes an input port, a dispersion component, a first filter, a redirection component and output ports. Input port is configured to enable incidence of the first beam and the second beam on the dispersion component; and the dispersion component is configured to decompose the first beam into a plurality of first sub-beams, the dispersion component is further configured to decompose the second beam into a plurality of second sub-beams, where a plurality of first sub-beams and a plurality of second sub-beams belong to different ranges. First filter is intended for: separation of transmission directions of a plurality of first sub-beams and a plurality of second sub-beams into different transmission directions in a first direction (X) based on different bands, enabling a plurality of first sub-beams to fall on a first region of the redirection component and allowing a plurality of second sub-beams to fall on a second region of the redirection component, where the first region and the second region are separated from each other in a first direction (X).

EFFECT: high efficiency of filtering pass band.
