Gain Stability of Erbium Doped Fiber Amplifier

采用 98 0nm无铝InGaAs/InGAsP/InGaP高功率量子阱激光器泵浦掺铒光纤放大器。在泵浦功率为2 0mW时 ,增益为 3 3dB ,最大增益系数 6 7dB/mW ,饱和输出功率为 6dBm。并给出掺铒光纤长度和泵浦功率与增益特性的关系 ,以及输出功率与增益特性的关系。

Erbium doped fiber amplifier was pumped by Al free 980nm InGaAs/InGaAsP/InGaP high power quantum well laser. At pump power of 20mW, the gain is 33dB, the maximum gain coefficient is 6 7dB/mW and the saturated output power is 6dBm. The gain is as a function of fiber length and pump powers, it is also as a function of output powers.
