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

Some new unusual physical phenomena and effects associated with dielectric mesoscale
particles with Mie size parameter near 10 were studied and have been discovered during …

Well-designed nanostructures enable increased light trapping, reducing the loss of single-
pass absorption and providing precise control over the microscale optical field, offering …

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 …

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

A specular-reflection photonic nanojet (s-PNJ) is a specific type of optical near-field
subwavelength spatial localization originated from the constructive interference of direct and …

In the past decade, the emergence of ultrathin 2D films consisting of only a few atomic layers
deposited on various substrates sparked new ideas and research. This Perspective provides …

Surface curvature can be used to focus light and alter optical processes. Here, we show that
curved surfaces (spheres, cylinders, and cones) with a radius of around 5 μm lead to …

Developing a universal and simple structure with an excellent fluorescence enhancement is
a highly desirable goal for practical applications in optical detection and imaging. Herein, a …
