  • Digital optical switch
    Patent number: 6701034
    Abstract: In a digital optical switch, an input waveguide and two output waveguides form a Y-shaped splitter or switch. Electrodes are positioned on each output waveguide at the junction with the input waveguide. The electrodes extend as narrow strips across the waveguides. The inner edges of the electrodes are curved to form a smooth continuation profile to the signal paths to reduce losses.
    Type: Grant
    Filed: October 19, 2001
    Date of Patent: March 2, 2004
    Assignee: National Research Council of Canada
