99% of international data travels through undersea fiber-optic cables using light pulses.
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) . Optoelectronics & Photonics: Principles & Pract...
When light hits a material, it can eject electrons or create electron-hole pairs, forming the basis for sensors and solar cells. photonics focuses on the generation
To build a photonic system, you generally need three things: you generally need three things:
