  • Zhang, Huqiang; Fitzgerald, John; Yu, Jeffrey; Chen, Ying; Phillips, Matt (Amer Inst 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 ...
  • 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 ...
  • 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 ...
  • Callsen, Gordon; Reparaz, J S; Wagner, M; Kirste, R; Nenstiel, C; Hoffmann, Axel; Phillips, Matt (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 ...
  • Muller, T.; Aharonovich, Igor; Wang, Z.; Yuan, X.; Castelletto, S.; Prawer, S.; Atarture, M. (American Physical Society, 2012)
    We report on the coherence properties of single photons from chromium-based color centers in diamond. We use field-correlation and spectral line-shape measurements to reveal the interplay between slow spectral wandering ...
  • Watts, Anne; Singh, Nagindar; Poulton, Christopher; Magi, Eric; Kabakova, Iv; Hudson, David; Eggleton, Benjamin (Optical Soc Amer, 2013)
    We investigate axial quantization in chalcogenide (As2S3) whispering gallery mode microfiber resonators. A microcavity is fabricated using a positive photoinduced index perturbation in the microfiber, and the modes are ...
  • Spence, Alistair; Poulton, Christopher (Elsevier, 2005)
    This paper considers the numerical computation of the photonic band structure of periodic materials such as photonic crystals. This calculation involves the solution of a Hermitian nonlinear eigenvalue problem. Numerical ...
  • Botten, Lindsay; Nicorovici, Nicolae; Mcphedran, Ross; De Sterke, C; Asatryan, Ara (American Physical Society, 2001)
  • Byrnes, Adam; Pant, R; Li, Eb; Choi, Dy; Poulton, Christopher; Fan, Sh; Madden, Steve; Luther-Davies, Barry; Eggleton, Benjamin (Optical Soc Amer, 2012)
    We report the first demonstration of a photonic chip based dynamically reconfigurable, widely tunable, narrow pass-band, high Q microwave photonic filter (MPF). We exploit stimulated Brillouin scattering (SBS) in a 6.5 cm ...
  • Pant, R; Byrnes, Andrew; Poulton, Christopher; Li, E; Choi, Dy; Madden, Steve; Luther-Davies, Barry; Eggleton, Benjamin (Optical Soc Amer, 2012)
    We report the first (to our knowledge) demonstration of photonic chip based tunable slow and fast light via stimulated Brillouin scattering. Slow, fast, and negative group velocities were observed in a 7 cm long chalcogenide ...
  • 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 the ...
  • Aharonovich, Igor; Castelletto, S.; Simpson, D.; Greentree, A.; Prawer, S. (American Physical Society, 2010)
    A detailed study of the photophysical properties of several chromium-related color centers produced within chemical vapor deposition diamond is presented. These emitters show narrow luminescence lines in the range of ...
  • 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 1100A?C were characterised by transmission electron microscopy and Raman spectroscopy. The nanocrystals were found to be ...
  • Balakrishnan, A.; Charbonneau, S.; Cheben, P.; Cloutier, M.; Dossou, Kokou; Delage, Andre; Erickson, L.; Gao, M.; Krug, P.; Lamontagne, B.; Packirisamy, Muthukumaran; Pearson, Matthew; Xu, D. (IEEE Publications, 2004)
    Silica planar waveguide echelle grating demultiplexers with 48 channels and 256 channels are described and demonstrated. Polarization effects due to stress birefringence and polarization-dependent grating efficiency have ...
  • Chen, Parry; Byrne, Michelle; Asatryan, Ara; Botten, Lindsay; Dossou, Kokou; Tuniz, A; Mcphedran, Ross; De Sterke, C; Poulton, Christopher; Steel, Michael (Taylor & Francis Ltd, 2012)
    The optical properties of photonic crystal slabs are often simulated with general three-dimensional methods such as finite-difference time-domain. Here we develop a multipole modal method, which is specialized to exploit ...
  • Frederiksen, Maj; Bochenkov, Vladimir; Sutherland, Duncan; Cortie, Michael (American Chemical Society, 2013)
    Large-area arrays of dispersed multilayer gold-dielectric nanocups were fabricated by colloidal lithography and studied by extinction spectroscopy. Hybridization of the elemental plasmons of the individual nanocups gave ...
