【摘要】 对掺铒光纤放大器 (EDFA)在L 波段 (L Band ,15 70～ 16 10nm)的增益谱特性进行了理论和实验研究。理论和实验研究得出在最佳反转粒子数密度 (N=0 39) 条件下 ,掺铒光纤L Band的平坦增益谱宽为 2 2nm(± 0 5dB) ,抽运功率与输入信号功率呈线性关系。实验测得L BandEDFA单信道小信号增益为 33dB。更多还原

【Abstract】 The investigation on the characteristics of L Band erbium doped fiber is reported. At the optimum population inversion level (N=0.39), the flattened amplification bandwidth of 22 nm(±0.5 dB) and linear relation between pump power and signal power were demonstrated theoretically and experimentally. Small signal gain of 33 dB was achieved at 1572 nm.更多还原
