| 摘 要： | 基于速率方程和光传输方程,对级联双包层铒镱共掺光纤放大器(Er3+/Yb3+ co-Doped Fiber Amplifier,EYDFA)进行了研究.数值模拟计算得到级联双包层EYDFA的最佳光纤长度,以及前后向泵浦功率之比和光隔离器位置对于增益以及噪音系数的影响.通过选择合适的前后向泵浦功率之比和隔离器的位置优化级联放大器结构,其增益提高了4 dB,噪音系数降低了近3 dB.

| Abstract: | The performances of two-stage double-clad Er3+/Yb3+ co-doped fiber amplifier(EYDFA)are analyzed based on the rate equation and light propagation equation.The optimum length and the influence of the ratio of forward and backward pump power on gain and noise characteristics of two-stage double-clad EYDFA are obtained with numerical simulation.The gain improvement of 4 dB and the noise figure reduction of 3 dB is obtained by choosing the optimum position of the isolator and the the ratio of forward and backwar... |
