To build a photonic system, you generally need three things:
When these two fields merge, we get "Optoelectronics"—devices that convert electrical energy into light, or vice versa. 1. Core Principles
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...
From non-invasive laser surgeries to Optical Coherence Tomography (OCT) used for high-resolution imaging of the human eye.
Tools that move light from A to B, most notably Optical Fibers . To build a photonic system, you generally need
Photodiodes and sensors that catch light and turn it back into a digital signal for a computer to read. 3. Real-World Applications
When light hits a material, it can eject electrons or create electron-hole pairs, forming the basis for sensors and solar cells. While electronic devices rely on the movement of
FaceID on smartphones, LiDAR for self-driving cars, and high-resolution OLED displays. 4. The Future: Integrated Photonics
