Analysis of erbium-doped superfluorescent fiber source in double-pass backward configuration

摘要: 通过编制1套图形界面的模拟分析软件,对双程后向结构掺铒光纤超荧光光源有关输出功率、带宽和平均波长特性进行了理论模拟。结果表明,通过选取适当的掺铒光纤长度,总能实现光源的平均波长不依赖于泵浦功率的高稳定性。并报道了研制的双程后向结构掺铒光纤超荧光光源。

Abstract: Erbium-doped superfluorescent fiber sources(SFS) in double-pass backward(DPB) configuration are characterized in output power,spectrum linewidth and mean wavelength through theoretical simulation.The results indicate that DPB SFSs mean wavelength can be adjusted insenstitive to pump power by properly adjusting the erbium-doped fiber(EDF) length,SFS with double-pass backward configuration made by us is also reported.
