| Abstract: | A multi-stage S-band EDFA is successfully designed using particle swarm optimization（PSO） algorithm.The simulation results show that flatten gain can be obtained at-20 dBm of signal output power and 1 486～1 520 nm,the total pump power of two stages is 380 mW,the average gain is more than 10 dB,the gain flatness is less than 0.1 dB,noise figure is less than 5 dB,which can meet the requirements of WDM/DWDM.In addition the allocation scheme and optimization method for improving the system performance of S-band EDFA,which inserts long-wavelength ASE filter,are analyzed and discussed. |
