The extraordinary sensitivity of plasmonic sensors is well-known in the optics and photonics
community. These sensors exploit simultaneously the enhancement and the localization of …

Plasmonic photocatalysis enables innovation by harnessing photonic energy across a broad
swathe of the solar spectrum to drive chemical reactions. This review provides a …

Nanoscale quantum emitters are key elements in quantum optics and sensing. However,
efficient optical excitation and detection of such emitters involves large solid angles because …

Silica nanoparticles are versatile platforms with many intrinsic features, such as low toxicity.
Proper design and derivatization yields particularly stable colloids, even in physiological …

Atoms and molecules are too small to act as efficient antennas for their own emission
wavelengths. By providing an external optical antenna, the balance can be shifted; …

Single photon sources can greatly benefit from specially designed structures that modify the
properties of the photon emitter. Dielectric cavities are often discussed, but they require a …

Spontaneous emission of fluorescent molecules or quantum dots is radiated along all
directions when emitters are diluted in a liquid solution, which severely limits the amount of …

We demonstrate single-photon superradiance from artificially constructed nonbonded zinc-
phthalocyanine molecular chains of up to 12 molecules. We excite the system via electron …

Recent progress in nanotechnology has enabled us to fabricate sub-wavelength
architectures that function as antennas for improving the exchange of optical energy with …

The present review on light emission stimulated by electrons tunneling inelastically through
a junction formed by a sample and a tip of a scanning tunneling microscope (STM) focusses …
