Key Concepts in Photonics and Optical Amplifiers

Photonics is the study and application of light (photons) to transmit, process, and store information. Optical amplifiers, a critical component of photonics, are devices that boost the intensity of optical signals without converting them into electrical signals. This process is essential for maintaining signal strength over long distances, especially in fiber-optic communication systems.

Key concepts include:
