Photonics

Photonics is the science and technology of harnessing light particles called photons to perform useful work, similar to how electronics uses electrons. It involves creating, controlling, and detecting light to build devices and systems like fiber optic cables, lasers, and solar panels that power much of modern communication and energy technology. By learning to manipulate light at incredibly small scales, scientists and engineers can transmit information faster, generate cleaner energy, and develop new medical tools that could revolutionize how we live.
