  • Control circuit, and system using same
    Patent number: 6362759
    Abstract: A circuit for selectably generating a plurality of preselected digital output signals which are precise and accurate, and among which the circuit can switch rapidly. In one embodiment, the outputs are connected to analog circuit signals, and drive a optical laser such that choice of the particular outputs of the circuit permits controllable switching of the laser output wavelength.

  • Optical waveguide apparatus and method for manufacturing
    Patent number: 4630883
    Abstract: A device and method for interconnecting multiterminal electronic devices. e device and method combine the use of input light sources, output light detectors and an optical waveguide matrix device for routing the signals from various preselected input terminals to various other output terminals. The optical waveguide matrix device includes a number of intersecting optical waveguides formed on a base. The intersecting waveguides are optically coupled by means of reflecting surfaces formed at the nodes of intersection.
