The localized coupling of surface and bulk plasmons maintained by inhomogeneity of the charge density distribution can significantly modify the waveguiding properties of a plasma-like medium. It is demonstrated that the electrically induced bulk plasmon resonance can efficiently modulate the traveling surface plasmon polaritons. This approach is shown to have a high potential for light manipulation...
Sub-nanometer transition layers that arise at interfaces between a metal and a dielectric sufficiently modify wave-guiding properties of metallic nanostructures. Through nonuniformities occurring inside the transition layers, the plasmon polariton modes maintained by a metal/dielectric interface couple to each other and change energy confinement in the nanostructure. In order to investigate this coupling,...
Recently, thin-film solar cells enhanced with plasmonic nanoparticles have attracted much attention of the scientific community. To improve the performance of such cells, an optimization of the nanoparticle parameters such as size, surface coverage and material is performed. Based on this optimization, the role of surface plasmons is discussed and analyzed with respect to optical absorption of the...
