Modular, extendable wavelength and space all-optical router

Abstract

The invention discloses a modular, extendable wavelength and space all-optical router. N single-mode input optical fibers are connected with a first group of wavelength conversion and routing modules and then enter a first space optical router, the output ends of the single-mode input optical fibers are connected onto a second group of wavelength conversion and routing modules and then are connected with an input port of a second space optical router after being subject to wavelength conversion and routing, and an output port of the second space optical router is connected with N single-mode output optical fibers to complete routing of optical signals to the corresponding single-mode output optical fibers. The first space optical router and the second space optical router work in a mirroring way. The modular, extendable wavelength and space all-optical router is applied to a wavelength division multiplexing optical fiber communication system and can achieve free conversion of N paths of optical signals in the optical fibers, complete routing of the optical signals from the input port to any output port, and achieve signal switching of the optical fibers; can achieve a complete routing function and increase the number of routing channels through cascading and linear increase of the wavelength conversion and routing modules. The whole routing structure can be integrated through the planar optical waveguide technology.
