Abstract :
A method is proposed to optimize the coupling differential equation of multiwave pumped fiber Raman amplifier and to solve the boundary problem of backward pump based on small signal theory. And, a genetic algorithm is used to approach the flatness of signal gain and noise spectra simultaneously.
