Fano resonances in plasmonic nanostructures: Modelling, large-area fabrication and applications

With their ability to concentrate light at a deep subwavelength scale by excitation of surface plasmons, metallic nanostructures play a major role in current nanoscience. Plasmonic modes with long radiative life times can drastically enhance the performance of nanophotonic devices. Their spectral response carries an asymmetric line shape with sharp spectral features, characteristic of Fano resonances. Insightful modelling and up-scalable fabrication of Fano-resonant plasmonic nanostructures is reported.
