  • Paired modes of heterostructure cavities in photonic crystal waveguides with split band edges 
    Mahmoodian Sahand; Sukhorukov Andrey; Ha Sangwoo; Lavrinenko Andrei; Poulton Christopher; Dossou Kokou; Botten Lindsay; Mcphedran Ross; De Sterke C (Optical Society of America, 2010)
    We investigate the modes of double heterostructure cavities where the underlying photonic crystal waveguide has been dispersion engineered to have two band-edges inside the Brillouin zone. By deriving and using a perturbative ...
  • Patterned growth and cathodoluminescence of conical boron nitride nanorods 
    Zhang Huqiang; Phillips Matthew; Fitzgerald J; Yu Jeffrey; Chen Ying (American Institute of Physics, 2006)
    We demonstrate a simple and effective approach for growing large-scale, high-density, and well-patterned conical boron nitride nanorods. A catalyst layer of Fe(NO3)3 was patterned on a silicon substrate by using a copper ...
  • Peptide toxins that selectively target insect NaV and CaV channels 
    King Glenn; Escoubas Pierre; Nicholson Graham (Landes Bioscience, 2008)
    Numerous metazoans express venoms for the purpose of defense, competitor deterrence, or prey capture. Peptide neurotoxins are particularly well represented in the venoms of arachnids, cnidarians and mollusks and these ...
  • Percolation in nanoporous gold and the principle of universality for two-dimensional to hyperdimensional networks 
    Smith Geoffrey; Maaroof Abbas; Cortie Michael (Amer Physical Soc, 2008)
    Percolation in nanoporous gold can be achieved with as little as 8% by volume of gold. Samples of nanoporous gold of various morphologies are analyzed with a combination of electrical and optical data. Growing thin films ...
  • Perfect Distinguishability of Quantum Operations 
    Duan Runyao; Feng Yuan; Ying Mingsheng (The American Physical Society, 2009)
    We provide a feasible necessary and sufficient condition for when an unknown quantum operation (quantum device) secretly selected from a set of known quantum operations can be identified perfectly within a finite number ...
  • Perfect Many-To-One Teleportation With Stabilizer States 
    Wang Gehong; Ying Mingsheng (Amer Physical Soc, 2008)
    We study the possibility of performing perfect teleportation of unknown quantum states from multiple senders to a single receiver with a previously shared stabilizer state. In the model we considered, the utilized stabilizer ...
  • Phonon Deformation Potentials In Wurtzite Gan And Zno Determined By Uniaxial Pressure Dependent Raman Measurements 
    Callsen Gordon; Reparaz J S; Wagner M; Kirste R; Nenstiel C; Hoffmann Axel; Phillips Matthew (Amer Inst Physics, 2011)
    We report the phonon deformation potentials of wurtzite GaN and ZnO for all zone center optical phonon modes determined by Raman measurements as a function of uniaxial pressure. Despite all the structural and optical ...
  • Photonic band structure calculations using nonlinear eigenvalue techniques 
    Spence Alistair; Poulton Christopher (Elsevier, 2005)
    The orientation of the endohedral La atom in La@C82 adsorbed on Cu(111) has been determined using the normal-incidence x-ray standing wave (NIXSW) technique. The NIXSW measurements were carried out using both the normal ...
  • Photonic Band Structure Calculations Using Scattering Matrices 
    Nicorovici Nicolae; Botten Lindsay; De Sterke C; Mcphedran Ross; Asatryan Ara (American Society for Microbiology, 2006)
    We consider band structure calculations of two-dimensional photonic crystals treated as stacks of onedimensional gratings. The gratings are characterized by their plane wave scattering matrices, the calculation of which ...
  • Photonic crystal devices modelled as grating stacks: matrix generalizations of thin film optics 
    Botten, L. C.; White, T. P., de Sterke, C. M., McPhedran, R. C., Asatryan, A. A., Langtry, T. N. (Optical Society of America, 2004)
    A rigorous semi-analytic approach to the modelling of coupling, guiding and propagation in complex microstructures embedded in twodimensional photonic crystals is presented. The method, which is based on Bloch mode ...
  • Photonic force spectroscopy on metallic and absorbing nanoparticles 
    Chaumet Patrick; Rahmani Adel; Nieto-Vesperinas Manuel (American Physical Society, 2005)
    We present a detailed study of the optical trapping and manipulation of nanoparticles with complex permittivity using an apertureless near-field probe. We use a three-dimensional, self-consistent description of ...
  • Physical and optical characterisation of Ge-implanted silica 
    Dowd Annette; Llewellyn David; Elliman Robert; Luther-Davies Barry; Samoc Marek; Fitz Gerald John (Elsevier Inc, 2001)
    Ge nanocrystals formed in silica by implantation with 1.0 MeV Ge ions and subsequent annealing at 1100°C were characterised by transmission electron microscopy and Raman spectroscopy. The nanocrystals were found to be ...
