为了满足分布式光纤光栅传感系统和超高速全光通信系统的需求，设计并实现了一种新型的铒铥混合掺杂的光纤超荧光超宽带光源。实验中用980和1480 nm激光二极管泵浦掺铒光纤，产生C+L波段的光；再利用 C+L波段光的30%光泵掺铥光纤，产生 S波段荧光，剩余70%的 C+L波段光与 S波段荧光通过耦合器耦合后输出，产生一个超宽带的 S+C+L 光源。该光源的总输出功率约为36 mW(15.6 dBm)，带宽从1460到1610 nm。对光源的带宽和功率等性能指标进行了测试，结果表明，可以满足分布式光纤光栅传感系统和全光通信系统应用的要求。

In order to satisfy the requirements of distributed fiber Bragg grating sensor systems and ultra-high-rate all-optical communication systems,this paper designs and implements a novel hybrid Erbium-and Thulium-Doped Fiber (TDF)super-fluorescent ultra-wideband light source.In the experiments,it uses 980 nm and 1 480 nm laser diodes to pump the Er-Doped Fiber (EDF),generating C+L band light.Then it uses 30% of this light to optically pump the TDF,producing S-band fluo-rescence light.Finally,it couples the remaining 70% of C + L-band light with the S-band fluorescent light,resulting in an ul-tra-wideband S+C+L light source.The total power of this light source is 36 mW (15.6 dBm),with a bandwidth of 1 460~1 610 nm.The test results of this light source show that its bandwidth,power and other performance indexes satisfy the re-quirements for the applications of distributed fiber grating sensor systems and all-optical communication systems.
