  • Waveguide coupler having continuous three-dimensional tapering
    Patent number: 8472766
    Abstract: A solid state waveguide coupler is provided including a first coupler end disposed on a solid state material substrate for connection to a first solid state waveguide located on the substrate and a second coupler end disposed on the substrate for connection to a second waveguide located on the substrate. A coupling span, comprising a waveguide material layer on the substrate, is disposed between the first and second coupler ends and tapers between a height of the first waveguide and a height of the second waveguide, tapers between a width of the first waveguide and a width of the second waveguide, and includes curved sidewalls along at least a portion of the tapered coupling span. In a method for fabricating the waveguide coupler, material is isotropically removed from a waveguide material layer on the substrate to produce tapered surfaces between the first waveguide and the second waveguide.
