TechnologyCaltech Chip Cuts Visible-Light Loss by 20xCaltech engineers printed fiber-optic-grade light pathways directly onto silicon wafers, a step that could sharpen lasers, clocks and quantum sensors.
TechnologyCaltech Chip Redirects Light in 74 FemtosecondsCaltech engineers built a nanoscale silicon surface that redirects one beam of light using another in just 74 femtoseconds — about the time light crosses a human hair.
TechnologyCaltech Chip Steers Light in Just 74 FemtosecondsA new nanoengineered silicon surface lets one laser beam redirect another almost instantly, clearing a speed limit that has capped optical computing for decades.
