Plasmon-mediated chemical reactions (PMCRs) are processes that make use of
nanostructure-based surface plasmons as mediators to redistribute and convert photon …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Tailored nanostructures can confine electromagnetic waveforms in extremely sub-
wavelength volumes, opening new avenues in lightwave sensing and control down to sub …

Confining light to sharp metal tips has become a versatile technique to study optical and
electronic properties far below the diffraction limit. Particularly near-field microscopy in the …

Waveguides play a key role in the implementation of on-chip optical elements and,
therefore, lie at the heart of integrated photonics. To add the functionalities of layered …

Bringing optical microscopy to the shortest possible length and time scales has been a long-
sought goal, connecting nanoscopic elementary dynamics with the macroscopic …

Quantum dot–like single-photon sources in transition metal dichalcogenides (TMDs) exhibit
appealing quantum optical properties but lack a well-defined atomic structure and are …

Nanolight sources, which are based on resonant excitation of plasmons near a sharp
