Optical communication in USA

"Optical communication uses the extraordinary speed of light as the signal, but right now it's still controlled and limited by electrical signaling at the end," said Yun-shik Lee, an associate professor in the OSU Department of Physics. "Electrons and wires are too slow, they're a bottleneck. The future is in optical switching, in which wires are replaced by emitters and detectors that can function at terahertz speeds."
