    White Tom; De Sterke C; Asatryan Ara; Mcphedran Ross; Langtry Timothy; Botten Lindsay (COIN/ACOFT 2003, 2003)
    A rigorous approach is developed for guiding and coupling in complex microstructured waveguides embedded in photonic crystals. The method, based on Bloch modes and generalized Fresnel coefficients, is applied to ...
  • Modelling time reversal experiments in the optical domain 
    Marks Benjamin; Steel Michael; Rahmani Adel (IEEE, 2008)
    We present a rigorous numerical study of the sub-wavelength focusing of electromagnetic waves using a time-reversal mirror, and show that the diffraction limit can be overcome in the optical domain.
  • Modes of composite defects in 2D photonic crystals 
    Poulton Christopher; Mcphedran Ross; Dossou Kokou; Mahmoodian Sahand; Botten Lindsay; De Sterke C; Asatryan Ara (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.
  • Nanoporous plasmonic coatings 
    Maaroof Abbas; Gentle Angus; Cortie Michael; Smith Geoffrey (The International Society for Optical Engineering, 2007)
    The electrical and optical properties of mesoporous gold are compared to those of thin porous gold films and a simulated thin film made by randomly distributing voids in gold, until the voids fill 76% of film volume. All ...
  • Nonlinear photonic crystals in chalcogenide for all-optical processing 
    Grillet Christian; Smith Cameron; Lee Michael; Magi Eric; Moss D; Eggleton Benjamin; Freeman Darren; Madden Steve; Luther-Davies Barry; Byrne Michael; Asatryan Ara; Botten Lindsay (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    We present the first experimental and theoretical results using nonlinear 2D photonic crystals in Chalcogenide. This scheme provides a promising platform to realize low power integrated all-optical switching and logic ...
  • Nonreciprocal transmission and low-threshold bistability in strongly modulated asymmetric nonlinear WBGs 
    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 ...
  • Novel high-performance scattering materials for use in energy saving light fittings and skylights based on polymer pigmented with polymer 
    Smith Geoffrey; Earp Alan; Franklin James; Mccredie Geoffrey (SPIE, 2001)
    Simple quantitative performance criteria are developed for translucent materials in terms of hemispherical visible transmittance, and angular spread of transmitted luminance using a half angle. Criteria are linked to ...
  • Numerically efficient multipole method for photonic molecules 
    Schwefel H; Poulton Christopher; Wang L (IEEE/LEOS, 2008)
    A novel and numerically efficient multipole formulation for the calculation of resonances of photonic molecules is presented. Photonic molecules are often modeled as two dimensional coupled dielectric disks. We use the ...
  • Offshore/onshore foundation programs: student perspective 
    Logan Peter; Cox Laurence; Cobbin Deirdre (IDP Education Australia, 2002)
    This presentation reports on a study of the educational quality and cultural sensitivity offoundation programs operated by Australian universities. The initial phase of the project, that involved a literature review and ...
