Scientists Transform Light Into Sound
They’re aglow with discovery. University of Sydney researchers have converted digital information stored as photons into sound waves for the first time, solving a decades-old scientific dilemma. A specially designed microchip takes nearly-300,000,000-meters-per-second light waves and slows them five-fold, allowing fiber optic cables, the backbone of the world’s internet, to transfer more data without the heat that’s generated by using electrons. This groundbreaking new technology could help cope with the increasing load on global fiber optic networks, and might eventually do away with overheated laptops and smartphones.
