Numerical simulations and experimental results of a hybrid EDFA-Raman amplifier

In this work numerical simulated and experimental results are obtained for a hybrid EDFA-Raman amplifier. Rigorous numerical models of both EDFA and Raman amplifiers are implemented and validated with experimental measurements. Results of ripple smaller than 1 dB are obtained for the hybrid amplifier gain, in 40 nm of bandwidth. The numerical model permits to achieve optimal design and to predict flat amplifier gain using genetic algorithm.
