Journal ArticleDOI
Optical properties of two interacting gold nanoparticles
W. Rechberger,Andreas Hohenau,Alfred Leitner,Joachim R. Krenn,Bernhard Lamprecht,Franz R. Aussenegg +5 more
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.
Journal ArticleDOI
Silver nanowires as surface plasmon resonators.
Harald Ditlbacher,Andreas Hohenau,Dieter Wagner,Uwe Kreibig,Michael C. Rogers,Ferdinand Hofer,Franz R. Aussenegg,Joachim R. Krenn +7 more
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.
Journal ArticleDOI
Electromagnetic energy transport via linear chains of silver nanoparticles.
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.
Journal ArticleDOI
Squeezing the Optical Near-Field Zone by Plasmon Coupling of Metallic Nanoparticles
Joachim R. Krenn,Alain Dereux,Jean-Claude Weeber,Eric Bourillot,Yvon Lacroute,J. P. Goudonnet,Gerburg Schider,W. Gotschy,Alfred Leitner,Franz R. Aussenegg,Christian Girard +10 more
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.
Journal ArticleDOI
Two-dimensional optics with surface plasmon polaritons
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.
