Photonic switch controls light passing through optical fibers faster than ever (Image 1)

06/27/2019 01:00 AM EDT

Engineers at the University of California, Berkeley, have built a new photonic switch that can control the direction of light passing through optical fibers faster and more efficiently than ever. The photonic switch is built with more than 50,000 microscopic "light switches" etched into a silicon ...
