【Abstract】 A novel optimal design method for fiber Raman amplifier is presented The propagation equations of fiber Raman amplifier back pumped at multiple wavelengths are solved with two steps. First, the simulated annealing algorithm is used to obtain required pump frequencies;then,by making use of average power analysis technique, the 4 step Adams_Bashforth method is adopted to design fiber Raman amplifiers with optimal gain flatness and gain bandwidth performances. This method is simple and efficient to design wide band fiber Raman amplifier.更多还原
