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 …

The growing demand for electronic devices, smart devices, and the Internet of Things
constitutes the primary driving force for marching down the path of decreased critical …

The structure of our material world is characterized by a large hierarchy of length scales that
determines material properties and functions. Increasing spatial resolution in optical imaging …

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 …

Traditional objective lenses in modern microscopy, based on the refraction of light, are
restricted by the Rayleigh diffraction limit. The existing methods to overcome this limit can be …

We study the near-field optical behavior of Fabry-Pérot resonances in thin metal nanowires,
also referred to as quasi one-dimensional plasmonic nanoantennas. From eigenmodes well …

Recent advances in nanolithography have allowed shifting of the resonance frequency of
antennas into the optical and visible wavelength range with potential applications, for …

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 …

We map in real space and by purely optical means near-field optical information of localized
surface plasmon polariton (LSPP) resonances excited in nanoscopic particles. We …

Apertureless scanning near‐field optical microscopy offers superb spatial resolution, but
interpreting the recorded signal can still be a challenge. Especially images of eigenmodes in …
