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 …

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

The optical trapping, sensing, and imaging of nanostructures and biological samples are
research hotspots in the fields of biomedicine and nanophotonics. However, because of the …

Recently, a type of curved light beams, photonic hooks (PHs), was theoretically predicted
and experimentally observed. The production of photonic hook (PH) is due to the breaking of …

When light propagates through the edge or middle part of a microparticle's incoming
interface, there is a basic rule that light converges and diverges rapidly or slowly at the …

We employ a genetic algorithm coupled with Mie theory to optimize the magnetic field
intensity profile of photonic nanojets (PNJs) generated by multilayer microcylinders at visible …

Herein, we report the theoretical investigation on the photonic nanojets (PNJs) of single
dielectric microspheres illuminated by focused broadband radiation (polychromatic light) …

In this work, we present an investigation of the process of photonic hook generation using
mesoscale finite-size graded-index elliptical particle under illumination of limited space. The …

A photonic nanojet (PNJ) is a tightly focused beam that emerges from the shadow surface of
microparticles. Due to its high peak intensity and subwavelength beam waist, the PNJ has …

We report an effective method to shape a photonic jet (PJ) generated by a dielectric cuboid
scatterer on a hollow reflection screen. The study focuses on the shaping of PJ by hollow …
