  • Composite subwavelength-structured waveguide in optical systems
    Patent number: 8503839
    Abstract: A waveguide cores consisting of a subwavelength grating permits transmission of light without diffraction in a discontinuous manner, wherein the energy is provided by field hopping between subwavelength material segments of higher index. The use of alternating segments permits design of waveguides having desired effective index, mode confinement factor, birefringence, polarization mode or mode dispersions, polarization dependent loss, thermal sensitivity, or nonlinear optical coefficient. An optical system comprises a waveguide having such a core, clad on at least one side, extending between two ends, and wavelength-limiting optical components in optical communication with the ends.
    Type: Grant
    Filed: January 13, 2012
    Date of Patent: August 6, 2013
    Assignee: National Research Council of Canada
    Inventors: Pavel Cheben, Przemek J. Bock, Jens H. Schmid, Dan-Xia Xu, Adam Densmore, Siegfried Janz
