Broadband raman amplifier analytical model under experimental validation

The experimental validation of a novel analytical model for broadband Raman amplifiers with multiple pump lasers is accomplished by confronting simulated and experimental results to counter-pumped distributed Raman amplifiers. Pump- pump and signal-pump interactions are included in the analytical formulation. Our model is applicable to distributed or lumped Raman amplifiers and, by optimizing the pump lasers wavelengths and powers it is possible to keep the gain ripple around ldB, since this is the value imposed by our experimental setup. The reduced computation time of just few seconds and the ability to keep a close agreement with experimental results make this formulation adequate for broadband Raman amplifiers´ analysis.
