    • Low pump limit of the bifurcation to periodic intensities in a semiconductor laser subject to external optical feedback 

      Lythe, Grant; Erneux, Thomas; Gavrielides, Athanasios; Kovanis, Vassilios (American Physical Society, 1997-06)
      The conditions for a bifurcation to periodic intensities (Hopf bifurcation) for low values of the pump current are examined using singular perturbation methods. We show that the frequency of the oscillations at the bifurcation ...
    • Low-frequency fluctuations in external cavity semiconductor lasers: understanding based on a simple dynamical model 

      Prasad, Awadhesh; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (Institute of Physics, 2001-08)
      We investigate the dynamical origin of low-frequency fluctuations (LFFs) in external cavity semiconductor lasers by utilizing a simplified, three-dimensional model derived from the infinite-dimensional Lang-Kobayashi (LK) ...
    • Luminescence efficiency and time dependence in a high electron affinity conjugated polymer 

      Samuel, I.; Rumbles, G.; Collison, Christopher; Moratti, S.; Holmes, A.; Crystall, B. (Elsevier: Synthetic Metals, 1996-01)
      We report measurements of the efficiency and time dependence of photoluminescence in a high electron affinity cyano-substituted derivative of poly (p-phenylenevinylene). In solution the photoluminescence quantum yield is ...
    • Luminescent colloidal silicon nanocrystals prepared by nanoseconds laser fragmentation and laser ablation in water 

      Svrcek, Vladimir; Mariotti, Davide; Hailstone, Richard; Fujiwara, Hiroyuki; Kondo, Michio (Materials Reseach Society (MRS), 2008-03)
      The surface states of silicon nanocrystals (Si-ncs) considerably affect quantum confinement effects and may determinate final nanocrystals properties. Colloidally dispersed Si-ncs offer larger freedom for surface modification ...
    • Magnetic field mapping 

      Hornak, Joseph; Szumowski, J.; Bryant, Robert (Wiley: Magnetic Resonance in Medicine, 1988-02)
      Homogeneous radiofrequency magnetic fields are necessary for production of high-quality magnetic images and for most forms of magnetic resonance spectroscopy. It is often convenient to map the radiofrequency homogeneity ...
    • Mainstreaming the deaf student 

      Foster, Susan; Emerton, Greg (Journal of Disability Policy Studies, 1991)
      In most areas of special eduction, Public Law 94-142 has been hailed as a breakthrough. By stipulating that children with disabilities be educated with the least restrictive environment, the law promotes schooling of these ...
    • Major loci influencing serum triglyceride levels on 2q14 and 9p21 localized by homozygosity-by-descent mapping in a large Hutterite pedigree
