  • Mahmoodian, Sahand; Dossou, Kokou; Poulton, Christopher; Mcphedran, Ross; Botten, Lindsay; De Sterke, C (Optical Society of America, 2010)
    We present a new method for designing mode fields of 3D photonic crystal heterostructure cavities. The method is several orders of magnitude faster than existing numerical methods and enables rapid design of heterostructure ...
  • Poulton, Christopher; Schmidt, Markus; Pearce, G; Kakarantzas, Georgios; Russell, P (Optical Society of America, 2007)
    We study numerically the formation of photonic band gaps and guided "defect" modes within two dimensional arrays of metallic nanowires. Attenuations as low as 1.7 dB/cm are predicted for silver wires at 1550 nm wavelength.
  • Dossou, Kokou; Botten, Lindsay; Mahmoodian, Sahand; Mcphedran, Ross; Poulton, Christopher; Asatryan, Ara; De Sterke, C (IEEE, 2008)
    We demonstrate the existence of a class of defects in 2D photonic crystals, for which the eigenstates depend only on the defect geometry, and not on details Re photonic crystal parameters or defect size.
  • Fujii, Masafumi; Takashima, Tetsuya; Maitra, Ayan; Leuthold, Juerg; Freude, Wolfgang; Poulton, Christopher (Optical Society of America, 2007)
    Nonreciprocal optical bistability is numerically investigated in InGaAsP/InP nonlinear waveguide Bragg gratings having a strong and asymmetric sidewall modulation. Minimum switching power as low as 77 mW is predicted by ...
