Quantum plasmonics is a rapidly growing field of research that involves the study of the
quantum properties of light and its interaction with matter at the nanoscale. Here, surface …

Nanostructured materials offer the possibility to tailor light–matter interaction at scales below
the wavelength. Metallic nanostructures benefit from the excitation of surface plasmons that …

Surface plasmon polaritons can be used to confine fields at the nanoscale and are now one
of the working horses of nanophotonics. This perspective deals with recent studies aiming at …

Nitrogen vacancy (NV) centres in diamond are promising elemental blocks for quantum
optics,, spin-based quantum information processing, and high-resolution sensing …

A study of the photophysical properties of nitrogen-vacancy (NV) color centers in diamond
nanocrystals of size 50 nm or below is carried out by means of second-order time-intensity …

We report an experimental technique to map and exploit the local density of optical states of
arbitrary planar nanophotonic structures. The method relies on positioning a spontaneous …

Surface plasmon polaritons (SPPs) are electromagnetic excitations coupled to electron-
charge density waves at metal-dielectric interfaces. They have recently been found to …

We present a scanning-probe microscope based on an atomic-size emitter, a single nitrogen-
vacancy center in a nanodiamond. We employ this tool to quantitatively map the near-field …

Inelastic electron tunnelling excitation of propagating surface plasmon polaritons (SPPs) on
a thin gold film is demonstrated. This is done by combining a scanning tunnelling …

Nitrogen–vacancy (NV) centers in diamond are generally recognized as highly promising as
indefinitely stable highly efficient single-photon sources. We report an experimental …
