Intel Demos Light Over Silicon

Intel's prototype is a big step toward replacing cooper cables or traces etched on circuit boards to connect computer components and move data around in individual devices. "The kind of change this speed increase could cause could exceed our collective imaginations," Rob Enderle, principal with the Enderle Group.

Microprocessor maker Intel (Nasdaq: INTC) has announced that it has developed a research prototype that it says is the world's first silicon-based optical data connection with integrated lasers. The link can move up to 50 gigabits of data per second -- about as much data as that contained in an entire HD movie.

Current chip manufacturing uses physical connections, rather than light, to transmit information from one part of a computer or other electronic device to another.
