Abstract: A wavelength specific optical equalizer for selectively attenuating discrete wavelength signals contained within a wavelength division multiplexed signal without affecting the adjacent signals. The wavelength equalizer includes a demultiplexer adapted to separate a wavelength division multiplexed signal into a plurality of discrete wavelength signals and to direct each of the discrete wavelength signals along a plurality of first optical paths. A micro-mechanical device comprising at least one micro-mirror is optically coupled with each of the first optical paths. A plurality of second optical paths is positioned to receive the discrete wavelength signals reflected from the respective micro-mirrors. At least one actuator is mechanically coupled with each of the micro-mirrors. The actuators are adapted to selectively displace one or more to divert at least a portion of the discrete wavelength away from the corresponding second optical paths. The orientation of the micro-mirror determines a signal strength of the discrete wavelength signal reflected to the corresponding second optical path. A multiplexer is provided to combine the discrete wavelength signals in the plurality of second optical paths into a reconstituted wavelength division multiplexed signal.

Abstract: An apparatus for equalizing polarization mode dispersion in an optical signal traveling through an optical fiber. 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. The fixed mirrors include a plurality of optical paths of differing lengths adapted to optically couple with the two rotating micro-mirrors. 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 is coupled to the first and second optical paths after the first variable delay generator. The beam combiner combines the first and second signals to form an optical output signal substantially compensated for polarization mode dispersion.

Abstract: 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.
