Embodiment Construction
[0061] The structure and working principle of the present invention will be introduced below in conjunction with the accompanying drawings in order of system scale from small to large.
[0062] figure 1 A schematic structural diagram of a single 1×(M1-2)×K1 three-stage optical switch subsystem of the present invention is given. A 1×(M1-2)×K1 three-stage optical switch subsystem 8 consists of an M1×B1 multimode interferometer 1 and K1×B1 digital optical phase conjugate reflectors 2, where M1 is greater than or equal to 4, and K1 is greater than Equal to 1, B1 is greater than or equal to 2, one side of M1×B1 multimode interferometer 1 is connected to M1 single-mode optical waveguides 3, of which the first single-mode optical waveguide is used as the input single-mode optical waveguide, and the remaining M1-1 single-mode optical waveguides The waveguide is used as an output single-mode optical waveguide; the other side of the M1×B1 multimode interferometer is connected to B1 sin...
