Abstract

In the weak coupling regime of light-matter interaction, the spontaneous emission of a fluorescent emitter can be tuned by placing it in a nanostructured environment such as plasmonic structures. In the strong coupling regime, the hybridization of the emitters with surface plasmons generates spatially extended coherent states called polaritons. These states span over a coherence length of several microns. We show how fluorescent quantum dots weakly coupled to a surface plasmon interact with J-aggregated organic molecules strongly coupled with a surface plasmon. We study how such interaction changes by tuning the wavelength of the quantum dots along the polariton bands.
