A group of researchers have developed a microprocessor that uses silicon photonics-based optics to send and receive data.
"For the first time a system - a microprocessor - has been able to communicate with the external world using something other than electronics," says Vladimir Stojanovic, associate professor of electrical engineering and computer science at the University of California, Berkeley.
