中文摘要：
设计和实现了一种双程后向泵浦结构的掺Er光纤（EDF）超荧光光源。通过1×2端的980nm耦合器和980nm的LD,实现了单管双泵浦作用,改善了光源输出光谱、带宽和平坦度,在未加滤波器的情况下,最高功率可达41.48mW（16.18dBm）,3dB带宽可达40nm,平坦度为±1.5dB。该光源结构简单、易于实现,应用于光纤光栅（FBG）传感系统,可实现多FBG传感信号峰值功率均衡。
英文摘要：
A broadband flatten Er-doped superfluorescent fiber source is designed and implemented,in which the double-pass backward pump is adopted.The dual pumps are obtained by using a 980 nm 1×2 coupler and a 980 nm laser diode（LD）.This configuration improves the characters such as power,bandwith and flatness of the source without using any external spectral filters.The highest power of the source is up to 41.48 mW（16.18 dBm）,the 3 dB band width is 40 nm,and flatness is ±1.5 dB,and the structure is simple.This source can be applicated in multipoints distribution fiber Bragg grating sensor system and can realize the peak power in the multi-FBG sensor signals.
