New “optical tornado” technology could transform quantum communication

Can light spin like a whirlwind? Researchers have now shown that it can. Scientists from the Faculty of Physics at the University of Warsaw, the Military University of Technology, and the Institut Pascal CNRS at Université Clermont Auvergne have created swirling "optical tornadoes" inside an extremely small structure. The advance points to a new way of building miniature light sources with complex shapes, which could support simpler and more scalable photonic devices for optical co...
