Sun Turns to Lasers to Speed Up Computer Chips 130
alphadogg writes to mention that Sun is attempting to move from the typical design of multiple small chips back to a unified single-wafer design. "The company is announcing today a $44 million contract from the Pentagon to explore replacing the wires between computer chips with laser beams. The technology, part of a field of computer science known as silicon photonics, would eradicate the most daunting bottleneck facing today's supercomputer designers: moving information rapidly to solve problems that require hundreds or thousands of processors."

Serial connections help with the timing, but do diddly for power and noise. That's where optical comes in.

I can't think of any good reason why you'd just be aiming a laser through the empty space inside a PC's case.
