Novel applications of nanophotonics, employing engineered metallic (plasmonic) and dielectric nanostructures, now enable unprecedented control over the flow of light and its spatial localization into tiny volumes. In a second exciting area of research, the temporal confinement of light down to attosecond durations has just become possible. We leverage advances in both these areas to create novel materials and nanostructures, to study their optical, electrical and catalytic properties, and use them to solve practical problems, e.g. in the areas of energy and photocatalysis.
