  • Systems and method for routing optical signals
    Patent number: 8811778
    Abstract: Systems and a method for routing optical signals are disclosed. One system includes a first large core hollow metal waveguide configured to guide a substantially coherent optical beam. A second large core hollow waveguide is optically coupled to the first waveguide with a coupling device. The coupling device is configured to divide the coherent optical beam into a transmitted beam and a reflected beam. Beam walk-off within the coupling device causes the transmitted beam to be shifted by an offset amount. The second large core hollow metal waveguide is shifted from the first large core hollow metal waveguide by approximately the offset amount to receive the shifted transmitted beam.

  • THREE-AXIS GYROSCOPE
    Publication number: 20130239679
    Abstract: Apparatus related to measuring angular velocities in three-space are provided. Drive masses distributed in a plane are force-oscillated in two orthogonal directions such that gyration of the collective is performed. Sense masses coupled by flexures to the drive masses are each displaceable along a respective single degree of freedom in response to angular velocities about a vector orthogonal to that degree of freedom. Electronic circuitry measures the respective sense mass displacements and provides corresponding signaling. The drive masses and sense masses can be formed such that a microelectromechanical system (MEMS) device is defined.

  • In-plane optical wave guide with area based splitter
    Patent number: 8526771
    Abstract: An optical interconnect includes a set of splitters. Each splitter includes a source waveguide, a reflection waveguide, an output waveguide, and a partially reflective mirror element with a reflective coating. The source waveguide and the reflection waveguide are optically coupled to the partially reflective element. A photonic signal from the source waveguide is partially reflected off the reflective coating as a reflected signal into the reflection waveguide. The output waveguide is optically coupled to the opposite surface and configured such that a non-reflected portion of the photonic signal propagates into the output waveguide. The reflective coating includes a reflected surface area interfacing with the photonic signal form the source waveguide, and power of the non-reflected portion is a function of the reflective surface area interfacing with source waveguide.

  • Hierarchical passive networks
    Patent number: 8521023
    Abstract: A communication network is described in which a number of computing nodes are situated in a logical multidimensional array and are linked by communication cables. The communication cables carry conduits connecting each node with all other nodes in the array so that a direct physical connection exists between every pair of computing nodes in the array. A method of providing interconnection among nodes in a communication network comprises arranging and connecting computing nodes in an array as described above, where each node passively redirects conduits to columns and rows in the array.
