  • Darcie, Thomas; Flynn, E (IEEE-inst Electrical Electronics Engineers Inc, 1992)
    We present spatially resolved measurements of carrier density in two 1.3 mum distributed feedback laser diodes. By measuring the response of the spontaneous emission intensity to a 50 MHz drive current we can observe small ...
  • Rahmani, Adel; Chaumet, Patrick; De Fornel, Frederique (American Physical Society, 2001)
    The modification of lifetime experienced by a fluorescent molecule placed in an arbitrary environment is investigated theoretically within the framework of linear response theory. We present a complete description of the ...
  • Klein, H. N.; Goldys, E. M.; Phillips, M. R.; Gelhausen, O. (Wileyv C H Verlag Gmbh, 2003)
    In-plane and depth-resolved cathodoluminescence (Cl.) microanalysis and spectroscopy was carried out to study the impact of electron injection on electro-migration and diffusion of native defects and residual impurities ...
  • Ton-That, Cuong; Shard, Alex; Egger, S.; Taninaka, Atsushi; Shinohara, Hisanori; Welland, Mark (Elsevier Inc, 2003)
    The growth of endohedral fullerene La@C82 films on Si(1 1 1) has been explored by scanning tunneling microscopy (STM). The STM images reveal the molecules are hexagonally close-packed in multilayer films with the inter-molecular ...
  • Poulton, Christopher; Guenneau, Sebastien; Movchan, Alexander (American Physical Society, 2004)
    We consider formulations for the Helmholtz operator for conically propagating modes on an array of high contrast ferromagnetic cylindrical inclusions in the limit when their wavelength outside the inclusions tends to ...
  • Wilcox, Stuart; Botten, Lindsay; Mcphedran, Ross; Poulton, Christopher; De Sterke, C (American Physical Soc, 2005)
    We present an exact theory for modeling defect modes in two-dimensional photonic crystals having an infinite cladding. The method is based on three key concepts, namely, the use of fictitious sources to modify response ...
  • Louvion Nicolas; Gerard Davy; Mouette J; De Fornel Frederique; Seassal Christian; Letarte Xavier; Rahmani Adel; Callard Segolene (American Physical Society, 2005)
    We report the direct, room-temperature, near-field mapping and spectroscopy of the optical modes of a photonic-crystal microcavity containing quantum wells. We use a near-field optical probe to reveal the imprint of the ...
  • Li, A. H.; Liu, H.; Lonescu, M.; Wang, X.; Dou, S. X.; Collings, E. W.; Sumption, M. D.; Bhatia, M.; Lin, Z.; Zhu, J. (American Institute of Physics, 2005)
    YBa2Cu3O7 films were fabricated by pulsed laser deposition on SrTiO3 s100d single-crystal substrates whose surfaces were modified by the introduction of Ag nanodots. The critical current density sJcd was found to increase ...
  • White, Tom; De Sterke, C; Mcphedran, Ross; Botten, Lindsay (Amer Inst Physics, 2005)
    We report on very high coupling efficiencies into rod-type photonic crystal (PC) slabs with unmodified interfaces. Three-dimensional finite difference time domain simulations show that reflected powers of less than 1.5% ...
  • Schelm, Stefan; Garrett, Paul; Fisher, W; Smith, Geoff (American Institute of Physics, 2005)
    Issues affecting the performance of polymers doped with conducting nanoparticles for use with windows are examined in terms of impact on visible and solar transmittance, solar heat gain, and residual scattering. Emphasis ...
  • Steel, Michael; Zoli, Rossella; Grillet, Christian; Mcphedran, Ross; De Sterke, C; Norton, Andrew; Bassi, Paolo; Eggleton, Benjamin (American Physical Soc, 2005)
    We study the analytic properties of the photonic crystal superprism resolution parameters p, q, and r introduced previously by Baba and Matsumoto [Appl. Phys. Lett. 81, 2325 (2002)], which characterize the potential ...
  • Marquarding, M.; Kilborn, V. A.; Mader, S.; O'Brien, J.; Doyle, M. T.; Ryder, S. D.; Minchin, R. F.; Garcia-Appadoo, D.; Drinkwater, M. J.; Ekers, R. D.; Gibson, B. K.; Freeman, K. C.; Jerjen, H.; Zwaan, M. A.; Stootman, F.; Sadler, E. M.; Ryan-Weber, E.; Stevens, J.; Meyer, M. J.; Gurovich, S.; Staveley-Smith, L.; Webster, R. L.; Putman, M. E.; Knezek, P. M.; Koribalski, B.

    The Northern HIPASScatalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of +20 < 8 < +25"30' to HICAT's Dec. range of -900 < ...
  • Burrage, Kevin; Burrage, Pamela; Higham, Desmond; Kloeden, Peter; Platen, Eckhard (American Physical Society, 2006)
    Wilkie (Phys. Rev. E 70, 017701 (2004)) used a heuristic approach to derive Runge-Kutta-based numerical methods for stochastic differential equations based on methods used for solving ordinary differential equations. The ...
