Abstract
We show strong coupling involving three different types of resonances in plasmonic nanoarrays: surface lattice resonances, localized surface plasmon resonances on single nanoparticles, and excitations of organic dye molecules. We study spatial coherence properties of a plasmonic nanoarray covered with a dye molecule film by a double slit experiment. A continuous evolution of coherence from the weak to the strong coupling regime is observed. Finally, we show with magnetic nanoparticles how the intrinsic spin-orbit coupling of the material interplays with the symmetries of the nanoparticle array, and mention our latest results on light-matter interactions in plasmonic lattices.
