摘　　要：对常见的单级、双级以及三级结构的C+L波段掺铒光纤ASE光源进行实验研究,对比它们的性能并分析各自的优缺点。结果表明,单级和双级结构的C+L波段掺铒光纤ASE光源C波段和L波段光谱很难实现最佳匹配,导致平坦度不理想。虽然三级双泵浦结构光源结构较前两种较复杂,但通过优化光源参数可以使输出光谱具有更好的平坦度,从而更好地满足分布式光纤光栅传感系统、长距离光纤通信系统、光纤陀螺以及光谱测试等应用场合的要求。Based on experimental research on three kinds of C＋L band Erbium-doped fiber amplified spontane-ous emission（ASE） light source including signal-stage, two-stage and three-stage structure, the characteristics arecompared and the advantages and disadvantages are analyzed. Results show that C band and L band spectrum of C＋L band Erbium-doped fiber ASE light source with single-stage and two-stage structure is difficult to realize optimalmatching and flatness is not ideal. Though the three-stage two-pumping structure light source is more complicatedthan that of the other two structures, the flatness of output spectrum is better through optimizing light source parame-ters. So the application requirements from distributed fiber Bragg grating（FBG） sensing system, long range fibercommunication system, fiber gyroscope and spectrum testing are better satisfied.
