University of Chicago Scientists Invent Smallest Known Way to Guide Light

Scientists at the University of Chicago found a glass crystal just a few atoms thick can trap and carry light—and could be used for applications. The material is visible as the thin line in the center of the plastic, held by study co-author Hanyu Hong.

­Directing light from place to the place is the backbone of our modern world. Beneath the oceans and across continents, fiber optic cables carry light that encodes everything from YouTube videos to banking transmissions—all inside strands about the size of a hair. University of Chicago Prof. Jiwoong Park, how
