As one of the key photonic devices, optical amplifier, especially optical fibre amplifier, has been playing an important role in the optical communications and laser physics.
A tiny part of the fluorescence light is captured by the fiber core and propagates together with any pump and signal along the fiber (in both directions). The focus is on the underlying physics and the resulting technical consequences; we do not simply treat a...

In a Raman amplifier, the signal is intensified by Raman amplification. Unlike the EDFA and SOA the amplification effect is achieved by a nonlinear interaction between the signal and a pump laser within an optical fiber. There are two types of Raman amplifier: distributed and lumped. A distributed Raman amplifier is one in which the transmission fiber is utilised as the gain medium by multiplexing a pump wavelength with signal wavelength, while a lumped Raman amplifier utilises a dedicated, shorter lengt
In the erbium-doped fiber amplifier (EDFA) the core of the optical fiber is co-doped with erbium ions. These have energy levels separated by energies corresponding to optical frequencies.
If the carrier density exceeds the transparency carrier density then the material can have optical gain and the device can be used to amplify optical signals via stimulated emission. During operation as an
A simplified explanation of how optical amplifiers work is as follows: The input optical signal passes through a special optical fiber within the amplifier. This special fiber is also driven (pumped) with a

The more guided modes a fiber has, the more fluorescence light can be captured, and the stronger ASE will be. The minimum possible amount of ASE is obtained for a single-mode fiber.
Since the 1960s, researchers knew how to make fiber lasers. Proper doping of the fiber (introducing small amounts of active elements into the glass fiber) allowed it to be pumped with external light
