Abstract
We show that a nanoparticle can serve as an efficient antenna for coupling of visible light into propagating plasmons of an Ag nanowire. For long wires, the coupling is maximal for incident light polarized perpendicular to the nanowire. For sub-10-mum nanowires, the polarization corresponding to maximum emission from the ends of the nanowire was found to be strongly dependent on the nanowire geometry and position of the vicinal nanoparticle. This nanoparticle antenna-based approach offers a potential strategy for optimizing plasmon coupling into nanoscale metallic waveguides.This publication has 12 references indexed in Scilit:
