Optical Amplifier Saturation Gain
This article explains the phenomenon of gain saturation, where the gain of an amplifier is reduced at high optical input power levels due to the depletion of stored energy in the gain medium. Gain saturation is very relevant e. It can be simulated with the software RP Fiber Power — even in cases where the time dependence of gain saturation and various frequency dependencies must be taken into account at the same time. Note the presence of a gain peak around 1530nm and a semi-flat gain. This chapter addresses the physics and applications of optical saturation, including optical absorption saturation and optical gain saturation. Optical saturation is a nonlinear optical process that usually ca...
