Abstract:
A hybrid optimal algorithm, named the SAA-PA in brief, based on the simulated annealing algorithm(SAA)and the Powell algorithm(PA)is proposed.The proposed algorithm puts the random search strategy of the SAA into the PA, which can prevent optimizing courses from trapping in local optima.The SAA-PA can effectively solve multimodal optimization in the distributed multi-pump Raman amplifier(DMRA).Optimal results show that, under the conditions of the on-off gain of 10 dB, the gain bandwidth of larger than 80 nm and the fiber length of 80 km, the gain ripple of less than 1.25 dB can be designed from the DMRA with only four backward pumps after the optimization of the proposed SAA-PA.Compared with the pure SAA, the SAA-PA can attain a lower gain ripple with the same number of pumps.Also, the relationship between the optimal signal bandwidth and the number of pumps can be simulated numerically with the SAA-PA.
