Plasmonic nanocavities: New design concepts and determination of the complete mode spectrum using electron-beam spectroscopies — •Stefan A. Maier — The Blackett Laboratory, Department of Physics, Imperial College London, London SW7 2AZ, United Kingdom
New design concepts such as the exploitation of dark modes, Fano resonances, and transformation optics allow for the design of plasmonic nanocavities with fascinating spectral properties, such as broadband superfocusing and invisibility dips, while at the same time retaining the deep sub-wavelength mode volume. A variety of cavity designs will be discussed, for applications ranging from optical sensing to photovoltaics. Furthermore, it will be shown that electron energy loss spectroscopy is an ideal tool for the determination and imaging of the mode spectrum of complex plasmonic cavities, including the elusive dark modes.
