When light hits a material, it can eject electrons or create electron-hole pairs, forming the basis for sensors and solar cells.
Just as the "silicon chip" revolutionized computing by shrinking giant transistors onto a tiny wafer, is now doing the same for light. We are moving toward "Light Chips" that process data at the speed of light with much less heat than traditional electronic processors.

From non-invasive laser surgeries to Optical Coherence Tomography (OCT) used for high-resolution imaging of the human eye.
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
The principle that allows light to "bounce" through glass fibers with almost zero loss, enabling high-speed internet. 2. Essential Components
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. FaceID on smartphones, LiDAR for self-driving cars, and
To build a photonic system, you generally need three things:
