What is an optical amplifier?

I will explain the types and principles of important devices that amplify light at high speeds.

Optical amplifiers are devices used to amplify optical signals and are widely utilized in optical communication systems. When optical signals are transmitted through optical fibers used in optical communication systems, losses occur due to phenomena such as Rayleigh scattering within the fiber, causing the light to attenuate. Therefore, it is necessary to use amplifiers that can compensate for this attenuation when constructing the system. By using optical amplifiers to amplify the signal, it is possible to achieve high-speed amplification without converting the light into electrical signals. This article explains the types and principles of optical amplifiers.
