Abstract
This application discloses an optical switch and an optical switching system. The optical switch includes a first waveguide, a second waveguide, and a first movable waveguide. The first waveguide and the second waveguide are immovable relative to a substrate. The first waveguide and the second waveguide are located in a first plane, and the first waveguide and the second waveguide do not intersect. The first movable waveguide is movable relative to the substrate. If the first movable waveguide is at a first location, the first movable waveguide is optically decoupled from the first waveguide and the second waveguide, and the optical switch is in a through state. If the first movable waveguide is at a second location, the first movable waveguide is optically coupled to the first waveguide and the second waveguide, and the optical switch is in a drop state.
