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 …

Localizing light to nanoscale volumes through nanoscale resonators that are low loss and
precisely tailored in spectrum to properties of matter is crucial for classical and quantum light …

Microcavities and nanoresonators are characterized by their quality factors (Q) and mode
volumes (V). While Q is unambiguously defined, there are still questions on V and, in …

We study the magnetic coupling between a metal-coated near-field probe and a photonic
crystal nanocavity. The resonance of the nanocavity shifts to shorter wavelengths when the …

We investigate dynamics of a laser-driven and dissipative system consisting of two nitrogen-
vacancy (NV) centers embedded in two spatially separated single-mode nanocavities in a …

Particles manipulation with optical forces is known as optical tweezing. While tweezing in
free space with laser beams was established in the 1980s, integrating the optical tweezers …

Advances in silicon photonics have resulted in rapidly increasing complexity in integrated
circuits. New methods that allow the direct characterization of individual optical components …

We demonstrate the nonresonant magnetic interaction at optical frequencies between a
photonic crystal microcavity and a metallized near-field microscopy probe. This interaction …

We experimentally observe a sizable and reversible spectral tuning of the resonances of a
two-dimensional photonic crystal microcavity induced by the introduction of a …
