From non-invasive laser surgeries to Optical Coherence Tomography (OCT) used for high-resolution imaging of the human eye. FaceID on smartphones, LiDAR for self-driving cars, and

99% of international data travels through undersea fiber-optic cables using light pulses. FaceID on smartphones

To build a photonic system, you generally need three things:

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.
