中文摘要	报道了采用两级级联双后向抽运的光源结构,实现高效率和线宽拓展的L波段掺铒光纤超荧光光源.通过数值模拟,研究了两级光纤长度分配和抽运功率比例对光源输出特性的影响.模拟表明,该结构可获得线宽拓展的平坦L波段光谱,相比常规L波段光谱线宽拓展了15 nm,达近60 nm.此外,抽运功率比例为1∶1时该结构的抽运转换效率最高.利用980 nm半导体激光器作抽运源,在抽动总功率206 mW时,实验上获得了输出功率62 mW,线宽56.6 nm的L波段光谱,抽运转换效率为30.1%.; A linewidth broadening and high efficiency erbium-doped superfluorescent fiber source(SFS) by using the cascaded dual-backward pumped configuration is proposed.The effects of fiber length arrangement and pump power ratio on the output characteristics of the L-band SFS are investigated by simulation.The simulational results show that the linewidth broadening L-band SFS can be achieved by the proposed design.The spectral linewidth is over 15 nm broader compared with the conventional L-band SFS,up to 60 nm.Further more,the design gives the highest pump efficiency at pump power ratio of 0.5.An L-band SFS of 62 mW output power,30.1% pump efficiency and 56.6 nm linewidth is experimentally achieved with 206 mW pump power of a 980 nm LD.; 【作者单位】集美大学物理系；【作者英文名】WANG Xiu-lin(Department of Physics,Jimei University,Xiamen,Fujian 361021,China)
