Abstract
This application discloses an optical switch and an optical switching system. Both a first waveguide and a second waveguide of the optical switch are immovable relative to a substrate and are located in a first plane. A first deformable waveguide is also located in the first plane. A first section of the first deformable waveguide is fixed relative to the substrate, and a second section other than the first section can deform under control of a first actuator. When the first deformable waveguide is in a first state, the first deformable waveguide is optically decoupled from the first waveguide and the second waveguide, and the optical switch is in a through state. When the first deformable waveguide is in a second state, the first deformable waveguide is optically coupled to the first waveguide and the second waveguide, and the optical switch is in a drop state.
