Optical switch and optical switching system

An optical switching system, wherein the optical switching system is an M×N optical switch matrix, comprising M×N optical switches, wherein the optical switch is disposed on a substrate, and the optical switch comprises a first waveguide, a second waveguide, and a first movable waveguide;

• the first waveguide is immovable relative to the substrate, and the first waveguide has a first input port IP1 and a first output port OP1;
• the second waveguide is immovable relative to the substrate, the second waveguide has a second output port OP2, the first waveguide and the second waveguide are located in a first plane, and the first waveguide and the second waveguide do not intersect;
