Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, ...
Researchers used the Poisson spot effect to create stable optical skyrmions with a laser and disc, simplifying studies for ...
A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...
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 ...
We propose a theoretical scheme for creating a two-dimensional Electromagnetically Induced Grating in a three-level \(\Lambda \)-type atomic system interacting with a weak probe field and two ...
