  • Segmented waveguide coupler
    Patent number: 7532793
    Abstract: A planar light wave circuit may be formed with a pair of waveguides arranged in close proximity to one another. At least one of the waveguides may be segmented. Through segmentation, the average mode-field diameter may be adjusted. Controlling the average mode-field diameter enables precise control over the coupling characteristics.
    Type: Grant
