Radiative Channeling of Nanowire Frenkel Exciton Polaritons through Surface Plasmons

Abstract

Plasmonic channeling of Frenkel exciton–polariton radiation from a vertically oriented, semiconducting organic nanowire on a gold thin‐film is demonstrated experimentally. Highly directional excitonic emission with a narrow spread of less than 4° is observed. This work has implications for improving the light collection efficiency of photonic and optoelectronic devices based on single organic nanowires.
