摘　　要：在理论分析的基础上 ,提出并实现了利用两个光纤光栅串联结构构成的平坦性较好 ,特定波段荧光功率输出较大的超荧光光源 ,并和光纤反射圈结构和没有反射装置的结构作了比较 .实验利用了 10 5 2 5 4— 10 5 3 42nm的反射率为 2 9 6dB和 10 5 2 62 4— 10 5 5 60nm的反射率为 3 4 4dB的两个宽带光纤光栅得到了 10 5 2 5— 10 5 5 5nm波段的3nm宽的比其他波段要高Based on theory analysis, we have demonstrated experimentally how to use cascaded wideband fibre Bragg grattings (FBGs) as reflectors in the superfluorescent fibre sources (SFS) configuration. In the experiment, we investigated the output characteristcs of the set-up with cascaded wideband FBGs, and compared it with those of the set-up with fibre ring reflector or without any reflector. From what we have achieved in the experiment, we find that the cascaded wideband FBGs is promising to be used as reflectors in SFS.
