Abstract: The movable part 21 is fastened to the substrate 11 via flexure parts 27a and 27b, and can move upward and downward with respect to the substrate 11. The substrate 11 also serves as a fixed electrode. The movable part 21 has second electrode parts 23a and 23b which can generate an electrostatic force between these electrode parts and the substrate 11 by means of a voltage that is applied across these electrode parts and the substrate 11, and a current path 25 which is disposed in a magnetic field, and which generates a Lorentz force when a current is passed through this current path. A mirror 12 which advances into and withdraws from the light path is disposed on the movable part 21. As a result, the mobility range of the movable part can be broadened, and the power consumption can be reduced, without applying a high voltage or sacrificing small size.

Abstract: A micrometer sized, single-stage, vertical thermal actuator with controlled bending capable of repeatable and rapid movement of a micrometer-sized optical device off the surface of a substrate. The vertical thermal actuator is constructed on a surface of a substrate. At least one hot arm has a first end anchored to the surface and a free end located above the surface. A cold arm has a first end anchored to the surface and a free end. The cold arm is located above the hot arm relative to the surface. The cold arm is adapted to provide controlled bending near the first end thereof. A member mechanically and electrically couples the free ends of the hot and cold arms such that the actuator bends generally at the flexure so that the member moves away from the substrate when current is applied to at least the hot arm.

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: A micro-electro-mechanical (MEM) optical device having a reduced footprint for increasing yield on a substrate. The MEM device includes an optical element having an outer edge and supported by a support structure disposed on a substrate. The support structure is mechanically connected to the substrate through first and second pairs of beams which move the structure to an active position for elevating the optic device above the substrate. When in an elevated position, the optical device can be selectively tilted for deflecting optic signals. The beams are connected at one end to the support structure, at the other end to the substrate and are disposed so that the first and second beam ends are located proximate the optical device outer edge. In a preferred embodiment, a stiction force reducing element is included on the outer edge of the optical device for reducing the contact area between the optic device edge and the substrate.
