  • Asatryan, Ara; Botten, Lindsay; Nicorovici, Nicolae; Mcphedran, Ross; De Sterke, C (Taylor & Francis Ltd, 2006)
    The frequency (Lamb) shift and local density of states (LDOS) in two-dimensional photonic crystals composed of a cluster of infinitely long circular cylinders is calculated classically using the radiation reaction mechanism. ...
  • Camnpbell, S; Botten, Lindsay; De Sterke, C; Mcphedran, Ross (Taylor & Francis Ltd, 2007)
    A formulation of the modal method for multi-element dielectric lamellar diffraction gratings is presented. It combines the conventional semi-analytic Kronig-Penny formulation with a Fresnel scattering matrix approach to ...

  • Niu, N; Liu, Tsung-Li; Aharonovich, Igor; Russell, Kasey; Woolf, Alexander; Sadler, Thomas; El-Ella, Haitham; Kappers, Menno; Oliver, Rachel; Hu, Evelyn (Amer Inst Physics, 2012)
    Effective, permanent tuning of the whispering gallery modes (WGMs) of p-i-n doped GaN microdisk cavity with embedded InGaN quantum dots over one free spectral range is demonstrated by irradiating the microdisks with a ...
  • Dossou, Kokou; Mcphedran, Ross; Botten, Lindsay; Asatryan, Ara; De Sterke, C (Optical Soc Amer, 2007)
    We consider defect modes created in complete gaps of 2D photonic crystals by perturbing the dielectric constant in some region. We study their evolution from a band edge with increasing perturbation using an asymptotic ...

  • Toth, Milos; Thiel, Bradley; Knowles, William (Cambridge Univ Press, 2010)
    We describe a feedback mechanism in the gas cascade amplification process used in magnetic immersion lens environmental scanning electron microcopy (ESEM). Feedback dominates gas gain under the conditions typically used ...
  • Morgan, Scott; Phillips, Matt (Amer Inst Physics, 2006)
    This work investigates the generation and detection of gaseous scintillation signals produced in variable pressure scanning electron microscopy through electron-gas molecule excitation reactions. Here a gaseous scintillation ...
  • Lutherborrow, Mark; Appavoo, Mathiyalagan; Simpson, Ann; Tuch, Bernard (Landes Bioscience, 2009)
    Previously, the insulin producing liver cell line HUH7-ins has been shown to synthesize, store and secrete insulin in response to glucose via secretory granules. The current study characterized the gene expression profile ...
  • Botten, Lindsay; De Sterke, C; Mcphedran, Ross; Nicorovici, Nicolae; Asatryan, Ara; Robinson, Peter (Kluwer Academic Publishers, 2001)
  • Botten, Lindsay; Asatryan, Ara; Nicorovici, Nicolae; Mcphedran, Ross; De Sterke, C (Elsevier Science Bv, 2007)
    The usual technique for calculating the mesoscopic conductance of materials is based on Pichard's transfer matrix method [J.L. Pichard, Thesis, University of Paris, Orsay, 1984]. The essential ideas of the theory of ...
  • Chaumet, Patrick; Rahmani, Adel; Bryant, Garnett (American Physical Society, 2003)
    We present a generalization of the coupled dipole method to the scattering of light by arbitrary periodic structures. This formulation of the coupled dipole method relies on the same direct-space discretization scheme that ...
  • Fukshansky-Kazarinova, Nina; Fukshansky, Leonid; Kuhl, Michael; J??Rgensen, B. (Optical Society of America, 1997)
    Measurements of the radiance distribution and ?uence rate within turbid samples with ?ber-optic radiance microprobes contain a large variable instrumental error caused by the nonuniform directional sensitivity of the ...
  • Johnston, Michael; Whittaker, David; Dowd, Annette; Davies, A.; Linfield, Edmund; Li, X; Ritchie, D (Optical Society of America, 2002)
    A compact, high-power emitter of half-cycle terahertz (THz) radiation is demonstrated. The device consists of an epitaxial InAs emitter upon a GaAs prism and produces THz pulses that are 20 times more powerful than those ...
  • Fu, Haitao; Jiang, Xuchuan; Yang, Xiaohong; Yu, Aibing; Su, Dawei; Wang, Guoxiu (Springer, 2012)
    This study demonstrates a facile but effective glycothermal method to synthesize vanadium oxide nanostructures for gas sensing detection. In this method, sodium orthovanadate was first dispersed and heated in ethylene ...

    SnO2 nanoparticles were dispersed on graphene nanosheets through a solvothermal approach using ethylene glycol as the solvent. The uniform distribution of SnO2 nanoparticles on graphene nanosheets has been confirmed by ...
  • Smith, Geoff (SPIE-Soc Photo-Optical Instrumentation Engineers, 2012)
    Nanotechnology, in particular nanophotonics, is proving essential to achieving green outcomes of sustainability and renewable energy at the production scales needed. Nanomaterials enable optimization of optical, opto-electrical, ...
  • Nicorovici, Nicolae; Mcphedran, Ross; Botten, Lindsay; Poulton, Christopher; Asatryan, Ara (Taylor and Francis, 2010)
    The local density of states (LDOS) is a function of spatial position and frequency which governs the radiation properties of sources placed within structured optical systems. We show how the enhancement or suppression of ...
