This review discusses how low-energy valence excitations created by swift electrons can
render information on the optical response of structured materials with unmatched spatial …

Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

For a physicist, and more generally for a scientist, one of the pleasures in everyday life is to
detect exemplifying manifestations and avatars of the topic he is working on. Why do small …

A metallic nanostructure consisting of a disk inside a thin ring supports superradiant and
very narrow subradiant modes. Symmetry breaking in this structure enables a coupling …

Manipulating light on the nanoscale has become a central challenge in metadevices,
resonant surfaces, nanoscale optical sensors, and many more, and it is largely based on …

Light absorbers available at present provide far from optimal black-body performance. The
need for more efficient absorbers is particularly acute on the microscale, where they can …

The combination of graphene with noble-metal nanostructures is currently being explored
for strong light–graphene interactions enhanced by plasmons. We introduce a novel hybrid …

Localized surface plasmon resonance (LSPR) excited by an incident light can normally
produce strong surface‐enhanced Raman scattering (SERS) at the nanogaps among …

Coherent anti-Stokes Raman spectroscopy (CARS) is a well-known tool in multiphoton
imaging and nonlinear spectroscopy. In this work we combine CARS with plasmonic surface …

Coupling of photons with molecular emitters in different nanocavities have resulted in
transformative plasmonic applications. The rapidly expanding field of surface plasmon …
