  • Patent number: 7440158
    Abstract: An apparatus includes a reconfigurable spatial light modulator, a light source, and a transmission filter. The reconfigurable spatial light modulator is capable of producing spatially varying amplitude and/or phase modulations of an incident light wavefront. The light source is configured to direct an illumination light beam towards the reconfigurable spatial light modulator such that the modulator produces a modulated outgoing light beam there from. The transmission filter is configured to spatially filter a light pattern formed by the outgoing light beam and to selectively transmit light from substantially only one diffractive order of the light pattern.

  • Publication number: 20080056723
    Abstract: An optical system may be configured as a receiving or as a transmitting system. As a receiving system, it is configured to receive at least one incident laser beam and project the beam into a spot on an array of actuable elements. The position of the spot is determined by the incident angular direction of the beam. The array is configured to track the position of the spot and at each tracked position of the spot to direct the beam onto an actual element. The actuable element tracks the spot so as to direct the beam onto a fixed path toward an optical receiver. As a transmitting system, it includes an actuable element configured to direct the light output from a laser into a spot on an array of actuable elements. The array is configured to track the position of the spot and at each tracked position of the spot to direct the light into a beam-forming system. The beam-forming system is configured to project the light in a transmitted beam having a variable angular direction.

  • Patent number: 7283753
    Abstract: In a system and method of optical communication, optical signals are generated in multiple wavelength channels. Each optical signal is passively transported from an origination node of a network to a destination node. The destination node is determined by the signal wavelength. For at least some signals, the passive transport includes transport through a branch point of the network, such that the signal wavelength determines the output branch through which the signal is routed. In certain embodiments, signals are generated according to a schedule devised to substantially prevent the concurrent arrival, at the same destination node, of signals having the same wavelength but coming from different origination nodes.

  • Patent number: 6798992
    Abstract: A device and method for detecting rotational drift of mirror elements in a MEMS tilt mirror array used in an optical crossconnect. The optical crossconnect directs optical signals from an input fiber to an output fiber along an optical path by rotatably positioning mirror elements in desired positions. A monitoring device disposed outside of the optical path is used to obtain images of the MEMS array or to transmit and receive a test signal through the crossconnect for detecting the presence of mirror element drift.

  • Patent number: 6704476
    Abstract: In an all optical switch an imaging system is interposed between the micro lens array and the moveable micro mirrors of a MEMS device to which, or from which, the light beams are directed. This causes an image of the micro lens array to be formed at the MEMS device, or vice-versa, thus effectively eliminating the distance between the micro lens array and the MEMS device. The imaging system may be a telecentric system. The size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror. The overall system is arranged to account for any inversions introduced.

  • Patent number: 6647172
    Abstract: Using an imaging system, an optical MEMS devices is imaged so that in combination with an actual one or more other optical MEMS devices, or images thereof, a single virtual optical MEMS device is formed that has the size of each of the optical MEMS devices combined. The physical size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror. The imaging system may reproduce the angle of reflection of the light from the micro mirror, e.g., using a telecentric system. A prism may be employed to align the various optical MEMS devices, or images thereof.

  • Patent number: 6519059
    Abstract: An arrangement is disclosed for providing optical wavelength adding/dropping. The arrangement includes two duplicated-port waveguide grating routers (WGR) and a plurality of attenuator-switches. The first WGR is configured as a 1×2N demultiplexer and the other as a 2N×1 multiplexer. Each WGR includes a duplicated plurality of input or output waveguides, wherein respective pairs of each plurality have substantially identical spectral characteristics. The first plurality of output waveguides of the first WGR is coupled to the first plurality of input waveguides of the second WGR. Attenuator-switches are inserted between these two pluralities of waveguides that can be used to block incident optical wavelengths corresponding to channels to be terminated at the node where the arrangement is provided. The second plurality of output waveguides in the first WGR are drop waveguides where dropped channels exist.

    Abstract: An optical crossconnect (OXC) fabric including an array of tiltable mirrors, a reflector and a plurality of optical fibers controls the position of the mirrors to optimize the transfer of a signal between an input optical fiber and an output optical fiber by monitoring the optical signal at an optical translation unit in each of the input optical fiber and the output optical fiber. The optical translation units are operable for regenerating the optical signals transmitted through the fibers.
