Optical Amplifier Basics, Types, Working & Applications
Erbium-Doped Fiber Amplifiers
Erbium-doped fiber amplifiers are the by far most important fiber amplifiers in the context of long-range optical fiber communications; they can efficiently amplify light in the 1. Its core is the erbium-doped optical fiber, which is typically a single-mode fiber. In the shown case, the active fiber is pumped with light from two laser diodes bidirectional pumping , although unidirectional pumping in the forward or backward direction co-directional and counter-directional pumping is also very common. See also Figure 1 in the article on erbium-doped gain media. Figure 1: Schematic setup of a simple erbium-doped fiber amplifier. Two laser diodes LDs provide the pump power for the erbium-doped fiber.
