Abstract: This application discloses an optical switch and an optical switching system. The optical switch includes a first waveguide, a second waveguide, and a movable waveguide, the first waveguide and the second waveguide are immovable relative to a substrate and are located in a plane, and an optical coupling relationship exists between the first waveguide and the second waveguide; the movable waveguide is movable relative to the substrate, and the movable waveguide is optically coupled to an input section or an output section of the first waveguide; when the movable waveguide is located at a first location, the movable waveguide is optically decoupled from the first waveguide, and the optical switch is in a through state; and when the movable waveguide is located at a second location, the movable waveguide is optically coupled to the input section or the output section, and the optical switch is in a drop state.
