  • Ideal bend contour trajectories for singlemode operation of lowloss overmoded waveguides 
    Koos Christian; Poulton Christopher; Zimmerman L; Jacome L; Leuthold Juerg; Freude Wolfgang (IEEE Publications, 2007)
    Bend designs for single-mode operation of low-loss overmoded waveguides are presented. A class of contour trajectories for minimum radiation loss is derived analytically, and numerical optimization is used to find ideal ...
  • Nonlinear silicononinsulator waveguides for alloptical signal processing 
    Koos Christian; Jacome L; Poulton Christopher; Leuthold Juerg; Freude Wolfgang (Optical Society of America, 2007)
    Values up to γ = 7×106/(Wkm) for the nonlinear parameter are feasible if silicon-on-insulator based strip and slot waveguides are properly designed. This is more than three orders of magnitude larger than for state-of-the-art ...
  • Numerical study of guided modes in arrays of metallic nanowires 
    Koos Christian; Jacome L; Poulton Christopher; Leuthold Juerg; Freude Wolfgang (Optical Society of America, 2007)
    We numerically investigate the band structure and guided modes within arrays of metallic nanowires. We show that bandgaps appear for a range of array geometries and that these can be used to guide light in these structures. ...
