Abstract

In this paper we demonstrate direct excitation of propagating plasmons in silver nanowires. The plasmons are excited either directly by an infrared excitation or indirectly via up-conversion process in rare-earth doped nanocrystals placed in the vicinity of the silver nanowires. In order to map propagating plasmons in silver nanowires, we designed an experimental setup which enables precise, diffraction-limited focusing of the laser, while at the same time both wide-field and confocal imaging of fluorescence.
