摘要： A system and method are used to route input signals from an input node to N output nodes. The system includes an input section that receives input signals, an output section that transmits output signals based on the input signals, and a switching section. The switching section includes switches that control transmission of the input signals from the input section to the output section. The switches can be latching micro-magnetic switches that include a magnet proximate to a substrate, a cantilever coupled to the substrate and positioned proximate to the magnet, the cantilever coupled to a magnetic material, and a conductor coupled to the substrate, the conductor conducting a current that induces a first torque in the cantilever.

摘要： A micro magnetic latching device. The device comprises a substrate having a moveable element supported thereon. The moveable element (cantilever) has a long axis and a magnetic material. The device also has first and second magnets that produce a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the long axis of the moveable element, wherein the first magnetic field is approximately perpendicular to a major central portion of the long axis. The device also has a coil that produces a second magnetic field to switch the movable element between two stable states, wherein only temporary application of the second magnetic field is required to change direction of the magnetization vector thereby causing the movable element to switch between the two stable states.

摘要： A new optical switch device and method of operating such a device overcomes alignment problems through the use of an optical signal-confining channel that may be embedded so as to confine optical signals in a desired propagation path such that the optical signal's alignment with the output is secured. Small-angle mirrors may be used so as to direct the optical signal into the intended optical signal-confining channels so as to achieve the desired optical switching. The mirrors could be latching micro-mirrors or non-latching micro-mirrors. Such mirrors could be controlled by electrostatic actuation, thermal actuation or electromagnetic actuation, or any other technique.
