TL;DR: In this paper, surface plasmon excitation in pairs of identical Au nanoparticles by optical transmission spectroscopy was studied and it was shown that with decreasing interparticle distance the surface plasm resonance shifts to longer wavelengths for a polarization direction parallel to the long particle pair axis whereas a blueshift is found for the orthogonal polarization.

TL;DR: It is demonstrated that the nonradiating character of the silver nanowires together with minimized damping due to the well developed wire crystal structure allow them to apply as efficient surface plasmon Fabry-Perot resonators.

TL;DR: The idea of a subwavelength-sized light guide represented by a linear chain of spherical metal nanoparticles in which light is transmitted by electrodynamic interparticle coupling may be useful for subwa wavelength transmission lines within integrated optics circuits and for near-field optical microscopy.

TL;DR: In this article, the experimental observation of near-field optical effects close to Au nanoparticles using a photon scanning tunneling microscope (PSTM) allowed an unprecedented direct comparison with theoretical computations of the optical near field intensity.

TL;DR: In this paper, the experimental realization of highly efficient optical elements built up from metal nanostructures to manipulate surface plasmon polaritons propagating along a silver/polymer interface is reported.
