Simulation of an inelastic dispersive phenomenon: stimulated Brillouin
Stimulated Brillouin scattering (SBS) is one of the most important nonlinear phenomena because it limits the maximum transmission power in modern optical communication systems.

The gain bandwidth is indicated below, and can change depending on the fiber type (e.g. dispersion compensating fiber, dispersion shifted fiber, normal single mode fiber).
Gain – amplifier, optical amplification
The gain achieved e.g. in a fiber amplifier or the gain medium of a laser depends on the population densities in different electronic levels, which themselves depend
