  • Bi-directional high-density optical switch
    Publication number: 20030086639
    Abstract: The present invention is a “bi-directional” high-density optical switch, which allows for size reduction of the optical switching matrix and the optical switching matrix package. Interlacing input and output channels and plurality of waveguides and 4 types of switching cells enable this high density optical switch to alternate the placement of the fiber guides on either side of the matrix substrate, leading to a significant overall reduction in the dimensions of the optical switching matrix.
