SURFACE LATTICE RESONANCE
In our recent work, appeared on ACS Nano, we demonstrate the possibility to tailor the plasmon-mediated strong light-matter coupling through the precise engineering and assembly of plasmonic nanostructures in identical nanoparticle lattices. By studying gap-coupled aluminum nanodisk dimer arrays, we demonstrate that the Q/V ratio of the resulting optical modes can reach a maximum when the plasmon and the lattice photon are mixed around 10% relative fraction, thus opening the way towards the exploitation of these lattice-plasmon modes for cQED applications.
