  • Planar lightwave circuit and a method for its manufacture
    Patent number: 9322994
    Abstract: A planar lightwave circuit (PLC) is disclosed having fixed thereto a coupling tube for coupling an optical fiber. The PLC comprises a planar optical substrate having in it an optical waveguide having an optical aperture located on an edge surface of the optical substrate and a tube formed having a lumen dimensioned to receive an optical fiber ferrule and an edge surface fixed to the substrate edge surface so that a cross section of the lumen at the edge surface is aligned with the optical aperture.
    Type: Grant
    Filed: December 27, 2012
    Date of Patent: April 26, 2016
    Assignee: COLORCHIP (ISRAEL) LTD.
