为了提高掺铒超荧光光纤光源的平均波长热稳定性，在掺铒超荧光光纤光源中加入了可调谐光子带隙光纤滤波器。这种简单的滤波器能够成功地将平均波长补偿到-40 °C至70°C范围内小于10 ppm。当环境温度控制在±0.5°C时，超荧光光纤光源（SFS）在11小时内表现出±1 ppm的长期平均波长稳定性。在974.2nm泵浦功率为60 mW时，最佳掺铒光纤长度为8 m，最终输出功率为8 mW。
A tunable photonic bandgap fiber filter was incorporated in an Er-doped superfluorescent fiber source to improve its mean wavelength thermal stability. This simple filter was able to successfully compensate the mean wavelength to less than 10 ppm from - 40°C to 70°C. When the environmental temperature was controlled to ±0.5°C, the superfluorescent fiber source (SFS) exhibited a long-term mean wavelength stability of ±1 ppm over 11 h. With 60-mW pump power at 974.2 nm, an optimal Er-doped fiber length of 8 m was found, and the final output power of the compensated SFS reached 8 mW.
