Caltech’s tiny new chip can steer light in 74 quadrillionths of a second

According to a report by Random News Portal… A new Caltech device can redirect a beam of light in just 74 femtoseconds using another beam and a nanoscale silicon metasurface. The breakthrough could pave the way for dramatically faster photonic communications, computing, and sensing technologies. complete report is on link below.
