Erbium-doped superfluorescent fiber sources (SFS) pumped near 980nm in double-pass backward (DPB) configuration have been characterized through theoretical simulation.

理论研究了双程构掺铒光纤超荧光光的特性。

Erbium ions concentration is obtained by the information of measured coefficients along with modeling of double-pass backward (DPB) superfluorescent fiber source (SFS).

再利用这些系行超萤光光纤光的模拟，得到掺铒光纤的浓度。
