The Military & Aerospace Electronics take:
15 April 2019 -- This optical "traffic cop" could one day revolutionize optical communications, and how information travels through data centers and high-performance supercomputers that are used for artificial intelligence and other data-intensive applications.
The photonic switch is built with more than 50,000 microscopic "light switches," each of which directs one of 240 tiny beams of light to either make a right turn when the switch is on, or to pass straight through when the switch is off.
The 240-by-240 array of switches is etched into a silicon wafer and covers an area only slightly larger than a postage stamp.
