This seminar will present the current nanoplasmonics research portfolio at Imperial College London, focusing both on fundamental aspects of optical nanocavity design, and applications in photovoltaics and biological sensing. Nanocavities based on Fano resonances and geometrical singularities allow control over the radiative properties, creating an either spectrally sharp or a broadband response. It will be shown that electron energy loss spectroscopy is a tool of choice for the determination of the full mode spectrum of such plasmonic nanocavities. The second part of the seminar will focus on more applied work, particularly plasmon-enhanced solar cells and forays into biochemical sensing.
