Vortex light carries orbital angular momentum (OAM) characterized by exp(ilθ), where θ is the angular coordinate and l is the topological charge (TC) 1. OAM beams have been widely used in a variety of ...

Austrian researchers have sent data through the turbulent air over Vienna using an orbital angular momentum modulated free-space laser beam. The experiment could open the door to high-speed quantum ...

Achieved the world's fastest real-time bidirectional wireless transmission at a total rate of 140 Gbps --- more than twice the speed of conventional technology --- using the millimeter-wave band ...
