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.

Abstract: The present invention discloses a mode multiplexer/demultiplexer and a switching node. The mode multiplexer/demultiplexer includes a multi-mode optical waveguide, a first transmission optical waveguide, and a second transmission optical waveguide. The multi-mode optical waveguide includes a first mode channel and a second mode channel. The first transmission optical waveguide includes a first coupling region that includes a first fundamental-mode channel, and the first fundamental-mode channel performs optical mode coupling with the first mode channel in the multi-mode optical waveguide. The second transmission optical waveguide includes a second coupling region that includes a second fundamental-mode channel, and the second fundamental-mode channel performs optical mode coupling with the second mode channel in the multi-mode optical waveguide. An effective refractive index of a fundamental-mode optical signal in the first coupling region is different from an effective refractive index of the same fundamental-mode optical signal in the second coupling region.

Abstract: Examples of a polarization independent optical device are described. One example polarization independent optical device includes an input/output preprocessing optical path and M add/drop optical paths. Any add/drop optical path can be configured to drop a first QTE and a first PTE that meet a resonance condition of a microring included in the add/drop optical path such that each add/drop optical path can be configured to drop a desired optical signal. Any add/drop optical path can also be configured to transmit an input optical signal to the input/output preprocessing optical path. Therefore, when any of the M add/drop optical paths is configured to drop a desired optical signal, another add/drop optical path can be configured to add a desired optical signal.
