    摘要: A polarization mode separator separates the optical signal into a first polarized signal and a second differently polarized signal traveling along respective first and second paths. A first variable delay generator located along the first path is adapted to selectively provide a first propagation delay to the first polarized signal. The first variable delay generator includes at least two rotating micro-mirrors and one or more fixed mirrors constructed on a surface of a substrate. A controller is coupled to the first variable delay generator. The controller is adapted to monitor the polarization mode dispersion in the optical signal and to position the rotating micro-mirrors to direct the first polarized signal along one of the plurality of optical paths. A beam combiner combines the first and second signals to form an optical output signal substantially compensated for polarization mode dispersion.

    摘要: A micrometer sized multi-directional thermal actuator capable of repeatable and rapid displacement in a substantially horizontal direction, a substantially vertical direction, and/or a combination thereof. The multi-directional thermal actuator constructed on a surface of a substrate includes three or more beams each cantilevered from one or more anchors at a first end to extend generally parallel to the surface of the substrate. A member mechanically and electrically couples the distal ends of the beams. Application of current to a circuit comprising combinations of any two or more of the beams displaces the member in one of three or more non-parallel radial directions, respectively.

    摘要: A MEMS-based device to steer and manipulate beams of light traveling in free-space in an optical switch. The optical switch is based on a rotating vertical micro-mirror constructed on a surface of a substrate. At least one input optical fiber is arranged to direct at least one optical signal through free-space along a first optical path parallel to the surface of the substrate. A plurality of output optical fibers are arranged to receive the optical signal traveling through free-space along other optical paths not co-linear with the first optical path. At least one substantially vertical, rotating micro-mirror assembly is constructed on the substrate. The assembly includes a rotating micro-mirror with a vertical centerline and an axis of rotation both perpendicular to the surface, but not co-linear. The rotating micro-mirror is rotatable between a first position not in the first optical path and at least a second position redirecting the optical signal to one of the output optical fibers.

    摘要: A micrometer sized, single-stage, horizontal and vertical thermal actuator capable of repeatable and rapid movement of a micrometer-sized optical device off the surface of a substrate. The horizontal and 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 and laterally offset from 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 exhibits horizontal and vertical displacement when current is applied to at least the hot arm.
