Coherent emission from a disordered organic semiconductor induced by strong coupling with surface plasmons (1111.5717v1)
Published 24 Nov 2011 in cond-mat.mtrl-sci and physics.optics
Abstract: In this Letter we show that the strong coupling between a disordered set of molecular emitters and surface plasmons leads to the formation of spatially coherent hybrid states extended on acroscopic distances. Young type interferometric experiments performed on a system of J-aggregated dyes spread on a silver layer evidence the coherent emission from different molecular emitters separated by several microns. The coherence is absent in systems in the weak coupling regime demonstrating the key role of the hybridization of the molecules with the plasmon.
