Different plasmonic based devices are fabricated using novel micro and nanofabrication techniques for single molecule detection: Self-similar Ag-nanosphere based plasmonic devices, device comprising tapered nanolens and photonic crystal cavity and, finally, Si micropillars based superhydrobhobic surface.
This work shows the production of self-assembled elongated nano-objects embedded in an oxide host oriented perpendicular to the substrate and their acousto-plasmonic dynamics. Electromagnetic “hot spots” are created that activate anomalous Raman vibrational modes.
A plasmon-mediated mechanism of cooperative emission by an ensemble of dipoles near a metal nanoparticle is studied. The radiation is dominated by plasmonic super-radiant states which survive dipole-dipole interactions and non-radiative losses in the metal.
