photonics
Light particle technology
Photonics is the science and technology of generating, controlling, and detecting light—particularly in the form of photons.
The field parallels electronics but uses light instead of electrons: fiber optic cables, laser systems, LED displays.
Photonics underlies telecommunications, medical imaging, and quantum computing.
Advances in photonics have revolutionized data transmission speeds.
