Confining photonic nanojet in a microwell on microsphere lens for highly efficient light focusing, signal amplification and quantitative detection
Pengcheng Zhang, Bing Yan, Guoqiang Gu +4
Dielectric microspheres or microbeads can squeeze light into the subwavelength scale via photonic nanojet (PNJ) focusing. This enables strong light-matter interactions within its f…

Inflection Point: A New Perspective on Photonic Nanojets
Guoqiang Gu, Pengcheng Zhang, Sihui Chen +2
When light propagates through the edge or middle part of microparticle's incoming interface, there is a basic rule that light converges and diverges rapidly or slowly at the output…
