Directional out-coupling of light from a plasmonic nanowire-nanoparticle junction

Danveer Singh, Arindam Dasgupta, Aswathy V. G. +2

We experimentally show how a single Ag nanoparticle (NP) coupled to an Ag nanowire (NW) can convert propagating surface plasmon polaritons to directional photons. By employing dual…
