Optically induced diffraction gratings based on periodic modulation of linear and nonlinear effects for atom-light coupling quantum systems near plasmonic nanostructures

During the recent decades, nonlinear optical properties of various atomic 1,2,3,4 and other coherent media 5,6 have been well studied due to quantum interference and coherence. As examples and owning ...

Synthesis of nano-optical elements for zero-order diffraction 3D imaging

A method is proposed to compute and synthesize a microrelief to produce a new nano-optical element for forming 3D images with full parallax at the zero order of diffraction. The synthesis of ...
