Abstract

Surface plasmon resonances can couple with molecular resonances (excitons) leading to weak or strong coupling regimes. The latter is always observed when the plasmon or the molecular exciton presents a large oscillator strength (high-Q plasmonic cavities or J-aggregates). We report here the observation of a strong coupling regime between the surface plasmon resonance of a nanoparticle array and the molecular excited state of photochromic molecules, both of them presenting weak oscillator strength.
