Drawing from the latest advances in metasurfaces and nanophotonics, researchers in the US have designed a new light source that can steer beams of incoherent light over ultrashort timescales. Developed by Igal Brener and colleagues at Sandia National Laboratories in New Mexico, the source features a reconfigurable metasurface that is embedded with quantum dots. With further development, the concept could be used to improve virtual reality displays, sensors for autonomous vehicles and lighting systems.
