Researchers build an all-optical transistor

July 8, 2013 9:30 am | by Larry Hardesty, MIT News Office | News | Comments

Optical computing could pay dividends for both conventional and quantum computers. But optical computing requires photons to modify each other’s behavior, something they’re naturally averse to doing: Two photons that collide in a vacuum simply pass through each other. Researchers have recently described the experimental realization of an optical switch that's controlled by a single photon, allowing light to govern the transmission of light.
