Abstract:
Microelectromechanical devices may include a substrate having first and second optical fibers thereon. An optical shutter may also be provided. This optical shutter is mechanically coupled to a first plurality of arched beams that are supported at opposing ends by support structures which may be mounted on the substrate. A second plurality of arched beams are also provided on a first side of the optical shutter. These arched beams are also supported at opposing ends by support structures. A first brake member is provided that is coupled to the second plurality of arched beams. This first brake member contacts and restricts the optical shutter from moving in the ±y-direction when the second plurality of arched beams are relaxed, but releases the optical shutter when the second plurality of arched beams move in the -x direction. This ability to restrict movement of the optical shutter when the second plurality of arched beams are relaxed provides a degree of nonvolatile position retention. A third plurality of arched beams are also preferably provided on a second side of the optical shutter. A second brake member, which is coupled to the third plurality of arched beams, also contacts and restricts the shutter member from moving in the ±y direction when the third plurality of arched beams are relaxed, but releases the optical shutter when the third plurality of arched beams move in the +x direction.
Abstract:
Microelectromechanical (MEM) Optical Cross-connect (OXC) switches having mechanical actuators are discussed. In particular, the MEM OXC switches can include a plurality of reflectors, wherein each of the plurality of the reflectors is movable to at least one of a respective first reflector position along a respective optical beam path from an associated input of the MEM OXC switch to an associated output thereof and a respective second reflector position outside the optical beam path. A mechanical actuator moves to at least one of a first mechanical actuator position and a second mechanical actuator position. A selector selects ones of the plurality of reflectors to be coupled to the mechanical actuator and at least one of the plurality of reflectors to be decoupled from the mechanical actuator, wherein the mechanical actuator is coupled to the selected ones of the plurality of reflectors in the first actuator position and wherein the mechanical actuator moves the selected ones of the plurality of reflectors from the respective first: reflector positions to the respective second reflector positions when the mechanical actuator moves from the first mechanical actuator position to the second mechanical actuator position. Related methods are also discussed.
Abstract:
A micromechanical system can include a substrate, an actuator, and an actuated element. In particular, the actuator can include a serpentine arrangement of alternating actuating and opposing segments anchored at a first end thereof to the substrate wherein the actuating segments deflect in response to actuation thereof so that a second end of the serpentine arrangement moves relative to the substrate upon deflection of the actuating segments. The actuated element is attached to the second end of the serpentine arrangement so that the actuated element moves relative to the substrate upon deflection of the actuating segments. Related methods and actuators are also discussed.
