Optoelectronics & Photonics: Principles & Pract... -

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

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.

Devices like LEDs (efficient light sources) and Laser Diodes (precise, coherent light).
