Diffraction minima resolve point scatterers at few hundredths of the wavelength
Resolving two or more constantly scattering identical point sources using freely propagating waves is limited by diffraction. Here we show that, by…

Non-invasive and fully two-dimensional quantitative visualization of transparent flow fields enabled by photonic spin-decoupled metasurfaces
Transparent flow field visualization techniques play a critical role in engineering and scientific applications. They provide a clear and intuitive…
Programmable electron-induced color router array
The development of color routers (CRs) realizes the splitting of dichromatic components, contributing to the modulation of photon momentum that act…
On-fiber photonic nanojet enables super-resolution in en face optical coherence tomography and scattering nanoscopy
Photonic nanojet (PNJ) of subwavelength spot-size originating at shadow side of a microsphere is projected as an imperative optical tool for micro-…
