Quantum Light: A Breakthrough in Medicine and Beam-Steering.

Researchers at Sandia National Laboratories have demonstrated the ability to dynamically steer light pulses from incoherent light sources using artificially structured materials called metasurfaces, made from tiny building blocks of semiconductors called meta-atoms that can be designed to reflect light very efficiently. This breakthrough could allow low-power, relatively inexpensive sources like LEDs or flashlight bulbs to replace more powerful laser beams in new technologies such as holograms, remote sensing, self-driving cars, and high-speed communication.
