Computing at the Speed of Light

The world of computing could change rapidly in coming years thanks to technology that replaces the metal wiring between components with faster, more efficient fiber-optic links.

"All communications over long distance are driven by lasers, but you've never had it inside devices," says Mario Paniccia, director of Intel's photonics lab in Santa Clara, CA. "Our new integrated optical link makes that possible."
