摘　　要：在分析L波段放大自发辐射(ASE)谱产生原理的基础上,设计出一种新颖的双级结构掺铒光纤ASE宽带光源,该光源可在两个端口分别输出高功率的C波段和L波段的ASE谱.设计将C波段ASE谱注入到掺铒光纤中作为L波段ASE谱的二次抽运源,使得L波段ASE谱功率得到了有效提高.优化光源结构参量后从两个端口分别获得了12.97 dBm和12.81 dBm的C波段和L波段ASE宽带谱.将两个输出端口组合得到了功率为15.9 dBm,泵浦转换效率达到21.6%的C+L波段超宽带ASE光源.A novel two-stage Er-doped ASE broadband light source with two output bands, i.e. C-band and L-band was designed and demonstrated based on the analysis of the principle of the L-band ASE spectrum. The output power of L-band ASE was effectively improved by injecting the C-band ASE into the erbium doped fiber acting as the secondary pumping source. An output power of 12.97 dBm for C-band ASE and 12.81 dBm for L-band ASE were obtained after optimizing the configuration parameters. A high efficiency CWL-band ASE source of 15.9 dBm output power with 21.6% pump conversion efficiency was obtained by simply combining the two output ports.
