摘要
报道了一种结构简单、工作在C+L波段的掺铒宽带光源。实验中用3 dB宽带耦合器作为光纤反射镜,同时利用功率控制电路使光源输出光稳定,先用两个980 nm二极管作为抽运源,将后向的C波段ASE重新引回光纤中,提高了抽运源的利用效率和光纤输出光的稳定性,优化掺铒光纤长度,获得了功率高达26.67 mW(14.26 dBm)的C+L波段ASE光输出,平均波长1550.887 nm。之后采用一个二极管实现双抽运得到了同样的结果。
A novel C+L band erbium-doped fiber broadband light source with high power was introduced.In the experiment,a fiber loop mirror made from 3 dB coupler was employed,meanwhile,power controlling circuit made fiber output steady.Single stage fiber and two pump LDs of 980 nm was used,and C-band amplified spontaneous emission of backward again enhanced the efficiency of LD and stability of output of fiber.Meanwhile,selecting appropriate Erbium-doped fiber length simultaneously got output of C+L band with power higher than 26.67 mW (14.26 dBm),whose average wavelength was 1 550. 887 nm.
