本文数值模拟了掺铒光纤超荧光光源的物理过程．对单程前向／后向结构光源的理论与实验结果进行了比较，两者达到了很好的符合，包括在输出信号频谱分布上．文中给出了有关双程后向结构光源特性的理论分析，首次表明，通过优化反射镜参数，在稳定的前提下，双程后向结构光源具有优于其他结构光纤光源的频带宽和泵浦率．
The behavior of Erbium-doped superflorescent fiber sources (SFS) is simulated numerically. Both simulated output power and spectral shape of SFS are shown to be in good agreement with the experimental results for the cases of SPB/SPF configurations. The theoretical analysis of SFS in double-pass backward configuration (DPB) are presented for the first time. It is shown that with certain reflectivity reflector, DPB SFS can provide not only higher pump efficiency but also larger spectral width than other configuration SFSs under stable operation conditions.
