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…

Photonic nanojet (PNJ) of subwavelength spot-size originating at shadow side of a microsphere is projected as an imperative optical tool for micro-…
