The control of light fields on subwavelength scales in nanophotonic structures has become
ubiquitous, driven by both curiosity and a multitude of applications in fields ranging from …

In this article, we present an overview of aperture and apertureless type scanning near-field
optical microscopy (SNOM) techniques that have been developed, with a focus on three …

Extraordinary optical transmission (EOT) is a term that refers to electromagnetic resonances
through sets of subwavelength apertures in either a flat or a corrugated metal film, providing …

Control of light–matter interactions at the nanoscale has advanced fields such as quantum
optics, photovoltaics and telecommunications. These advances are driven by an improved …

We report on an experimental technique to quantify the relative importance of electric and
magnetic dipole luminescence from a single nanosource in structured environments. By …

Structure, dynamics, and coupling involving single-molecules determine function in catalytic,
electronic or biological systems. While vibrational spectroscopy provides insight into …

We demonstrate the enhancement of magnetic dipole spontaneous emission from Eu^ 3+
ions by an engineered plasmonic nanostructure that controls the electromagnetic …

We study experimentally both magnetic and electric optically induced resonances of silicon
nanoparticles by combining polarization-resolved dark-field spectroscopy and near-field …

Recent work has shown that optical magnetism, generally considered a challenging light–
matter interaction, can be significant at the nanoscale. In particular, the dielectric …

With recent advances in nanofabrication technology, various metallic gap structures with
gap widths reaching a few to sub-nanometer, and even 'zero-nanometer', have been …
