摘要
利用双程双向泵浦单级掺铒光纤的结构实现高效率的L波段掺铒光纤放大自发辐射输出,同时选择1480nm半导体激光器作为泵浦源,高掺杂铒光纤为增益介质,通过优化铒光纤长度,获得了在1566~1604nm(38nm),自发辐射谱功率高于-16dBm,总输出功率13.7dBm的L波段掺铒光纤放大自发辐射光源。该光源结构相比于双程前向泵浦结构的L波段掺铒光纤放大自发辐射光源,其泵浦效率从11.8%提高到23.4%。
A double-pass bi-directional (DP-BD) pump configuration is proposed for the high efficiency L-band ASE. A L-band ASE of 13.7 dBm output power and 38 nm bandwidth of 1566~1604 nm where the ASE power intensity is higher than -16 dBm is obtained by selecting 1480 nm LD and heavily doped erbium fiber with optimized length simultaneously. The DP-BD ASE source has a pump conversion efficiency of 23.4% which is larger than that by double-pass forward (DPF) configuration of 11.8%.
