ABSTRACT
We investigate quantitatively the local coupling efficiency of a strongly focused laser beam to surface plasmon polaritons on a gold thin film. The coupling is mediated by gold ridges with nanoscale cross section. The coupling efficiency is determined by measuring the leakage radiation emitted by the surface plasmon polaritons into the glass substrate supporting the thin film. © 2003 American Institute of Physics.

    Anisotropic and enhanced nonlinear absorption (NLA) has been observed from aligned gold nanorods (GNRs) embedded in a poly(vinyl alcohol) film, which was realized by a stretched-film method. Open-aperture Z-scan experiments revealed that the stretch process enhanced the NLA coefficient by...

    We report a significantly enhanced photon drag effect (PDE) in a Au thin film at the surface plasmon resonance when the film is mounted in the Kretschmann-Raether geometry. The PDE is observed in the form of an electrical direct current induced by optical excitation. We discuss a model to...

    We observed azimuthal distributions of surface-plasmon-coupled emission from thin layers of randomly oriented and oriented sexithiophene molecules deposited on 50-nm-thick Ag films. For the randomly oriented layer, we observed a uniform and isotropic cone of emission, showing that the surface...

    Experimental results are presented for light-on-light modulation at low rates using coupling to nonradiative surface plasmons and their associated thermal effects in a thin gold foil. It is first shown that several modulated Gaussian beams simultaneously exciting surface plasmons in the same...

    In this paper, we investigated an essential precursor of superlensing: enhancing the transmission of evanescent waves assisted by excitation of surface plasmon. Using natural roughness as a well characterized grating, the transmission of evanescent waves is studied through silver thin films of...
