  • Blue, surface-emitting, distributed feedback polyfluorene lasers 

    Heliotis, G.; Xia, R.; Bradley, D. D. C.; Turnbull, G. A.; Samuel, I. D. W.; Andrew, P.; Barnes, William L. (American Institute of Physics, 2003)
    We report the fabrication of optically-pumped solid-state distributed feedback lasers utilizing two blue-light-emitting semiconducting polyfluorenes as gain media. The lasers were readily fabricated by solution deposition ...
  • Low threshold edge emitting polymer distributed feedback laser based on a square lattice 

    Vasdekis, A. E.; Turnbull, G. A.; Samuel, I. D. W.; Andrew, P.; Barnes, William L. (American Institute of Physics, 2005)
    We report the demonstration of a low-threshold, edge-emitting polymer distributed feedback laser based on a square lattice. The lattice constant was 268 nm, which corresponds to a lattice line spacing in the ΓM symmetry ...
  • Molecular fluorescence above metallic gratings 

    Andrew, P.; Barnes, William L. (American Physical Society, 2001)
    We present measurements of the fluorescence of emitters located in close proximity (d<λ) to metallic grating surfaces. By measuring both the spontaneous emission lifetime and angle-dependent radiation pattern of a monolayer ...
  • Operating characteristics of a semiconducting polymer laser pumped by a microchip laser 

    Turnbull, G. A.; Andrew, P.; Barnes, William L.; Samuel, I. D. W. (American Institute of Physics, 2003)
    We report the demonstration of a compact, all-solid-state polymer laser system featuring a microchip laser as the pump source. The laser was configured as a surface-emitting, two-dimensional distributed feedback laser, ...
  • Optical properties of a light-emitting polymer directly patterned by soft lithography 

    Lawrence, J. R.; Andrew, P.; Barnes, William L.; Buck, M.; Turnbull, G. A.; Samuel, I. D. W. (American Institute of Physics, 2002)
    We present the optical properties of a directly patterned light-emitting polymer. The patterned poly(2-methoxy-5-(3',7'-dimethyloctyloxy)-paraphenylenevinylene film is fabricated using hot embossing lithography. The effect ...
  • Photonic band structure and emission characteristics of a metal-backed polymeric distributed feedback laser 

    Andrew, P.; Turnbull, G. A.; Samuel, I. D. W.; Barnes, William L. (American Institute of Physics, 2002)
    Optical losses associated with the metallic contacts necessary for charge injection are an obstacle to the development of an electrically pumped polymer laser. We show that it may be possible to overcome these losses by ...
  • Photonic mode dispersion of a two-dimensional distributed feedback polymer laser 

    Turnbull, G. A.; Andrew, P.; Barnes, William L.; Samuel, I. D. W. (American Physical Society, 2003)
    We present an analysis of the photonic mode dispersion of a two-dimensional (2D) distributed feedback polymer laser based on the conjugated polymer poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene]. We use a ...
  • Relationship between photonic band structure and emission characteristics of a polymer distributed feedback laser 

    Turnbull, G. A.; Andrew, P.; Jory, M. J.; Barnes, William L.; Samuel, I. D. W. (American Physical Society, 2001)
    We present an experimental study of the emission characteristics and photonic band structure of a distributed feedback polymer laser, based on the material poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene]. We ...
