Color-coded surgery. Graphene optical modulators could lead to ultrafast communications. Scientists at the University of California, Berkeley, have demonstrated a new technology for graphene that could break the current speed limits in digital communications. The team of researchers, led by UC Berkeley engineering professor Xiang Zhang, built a tiny optical device that uses graphene, a one-atom-thick layer of crystallized carbon, to switch light on and off.
This switching ability is the fundamental characteristic of a network modulator, which controls the speed at which data packets are transmitted. Everyone needs one of these. Dichloroacetate (DCA) - Cure for Cancer ? How differential steering works. Professor of Theoretical Physics, CUNY.
