Numerical Analysis of Er^(3+)/Yb^(3+)Co - doped Double-clad Fiber Amplifiers for Gain and Noise Characteristics

基于速率方程和光传输方程,对980nm激光泵浦Er3+/Yb3+共掺双包层光纤放大器的增益和噪声特性进行了分析。数值模拟结果表明,在小信号和大信号情况下,双包层Er3+/Yb3+共掺光纤放大器在1520nm～1570nm波长范围内都具有良好的增益和噪声特性。

Er^(3+)/Yb^(3+)Co-doped double-clad fiber amplifier pumped at 980 nm is analyzed for gain and noise characteristics based on the rate equation and light propagation equation. And the numerical simulation result shows that, under the conditions of both small and large signals, Er^(3+)/Yb^(3+)co-doped double-clad fiber amplifiers have good gains and noise characteristics within the range of 1520nm ～ 1570nm wavelength.
