Light Controls Light at Near-Light Speed | Science News
Caltech just shattered speed limits with a chip that steers light in 74 quadrillionths of a second—faster than light crosses a human hair. Using one beam to control another, this breakthrough bypasses traditional delays by harnessing a nanoscale metamaterial that amplifies the optical Kerr effect. The team says laser pulses, not the material, currently cap performance—meaning even faster tech is on the horizon. Published in Nature Nanotechnology, this could revolutionize computing and communication. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn…
