When light hits a material, it can eject electrons or create electron-hole pairs, forming the basis for sensors and solar cells.

99% of international data travels through undersea fiber-optic cables using light pulses. When light hits a material, it can eject

are the engines behind our modern digital world. While electronic devices rely on the movement of electrons through semiconductors, photonics focuses on the generation, manipulation, and detection of photons (light particles) . are the engines behind our modern digital world

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.

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.
