Structured light has enabled access to new physics and applications, and has particular
potential in nanoscience. Here, we present a concept for creating light fields with constant …

Higher-order modes and hollow-core waveguides are highly relevant research directions in
photonics, while most studies are solely focused on fundamental modes. This work …

Here, we present the concept of flat-field capillary-assisted nanoparticle tracking analysis for
the characterization of fast diffusing nano-objects. By combining diffusion confinement and …

Here, we unlock the properties of the recently introduced on-chip hollow-core microgap
waveguide in the context of optofluidics which allows for intense light-water interaction over …

Here, we demonstrate the realization of hollow-core light cages (LCs) on commercial step-
index fibers using 3D nanoprinting, resulting in fully fiber-integrated devices. Two different …

Nanoparticle tracking analysis is an optical and video-based technique for dynamic
monitoring and determining the size distribution of diffraction-limited objects in fluids. Due to …
