99% of international data travels through undersea fiber-optic cables using light pulses.
Just as the "silicon chip" revolutionized computing by shrinking giant transistors onto a tiny wafer, is now doing the same for light. We are moving toward "Light Chips" that process data at the speed of light with much less heat than traditional electronic processors. Optoelectronics & Photonics: Principles & Pract...
This is the "magic" behind lasers, where an incoming photon triggers an atom to drop to a lower energy state, releasing a second, identical photon. releasing a second
