Researchers use circularly polarized light to control the direction of exciton polaritons in 2D semiconductors, enabling new tools for nanoscale photonics. (Nanowerk Spotlight) Directing light along ...
Vortex phenomena are widespread in nature, from typhoons to ocean currents. In the field of optics, vortex beams, which carry orbital angular momentum, have spiral wavefronts and ring-shaped intensity ...
