【摘要】 本文对低泵浦功率下１４８０ｎｍ泵浦的掺饵光纤放大器的特性进行了数值分析，分别给出了正，反向泵浦下大信号（１ｍＷ）输入时掺饵光纤放大器的增益──泵浦功率和噪声指数──泵浦功率曲线，说明了低泵浦功率对掺铒功率对掺期铒光纤放大器特性的影响。更多还原

【Abstract】 This paper perfomed a numerical analysis of characteristics of an Erbium-doped fiber amplifier with low pump power under co-and counter-propagating pumping schemes at 1480nm band, respectively. We obtained gain-pump power and noise figure pump power curves under large signal launching power condition, which could predict the performances of the EDFA.更多还原
