Material selection is a critical factor that affects the performance of devices and parts on a
microscale. Glass is a candidate material for micro applications as it possesses notable …

Dielectric microelements with circular symmetry have shown interesting optical properties:
photonic nanojets (PNJs) and whispering gallery modes (WGMs). They can confine light …

Dielectric microspheres with appropriate refractive index can image objects with super-
resolution, that is, with a precision well beyond the classical diffraction limit. A microsphere is …

This paper pertains to a long-standing debate about the quantification criteria and
mechanisms of optical superresolution in microsphere-based nanoscopy. Its super …

The photonic nanojet (PNJ) is a narrow high-energy beam that was originally found on the
back side of all-dielectric spherical structures. It is a unique type of energy concentration …

Overcoming the classical diffraction limit in optical microscopy is known to be achievable by
a variety of far-field and near-field microscopy techniques. More recently, so-called micro …

Nanostructured surfaces and devices offer astounding possibilities for biomedical research,
including cellular and molecular biology, diagnostics, and therapeutics. However, the wide …

We focus on physically analyzing the origins of the numerical aperture (NA) and the
spherical aberration of the microsphere with wavelength scale radius. We demonstrate that …
