Experimental Study on the Double-cladding Er^(3+)/Yb^(3+) Co-doped Superfluorescent Fiber Source

报道了基于双程后向单级泵浦结构的宽带Er3+/Yb3+共掺双包层光纤超荧光光源的实验研究结果。采用980nm泵浦源,通过优化泵浦功率和光纤长度,在波长1550nm处,实验仅用1m Er3+/Yb3+共掺双包层光纤获得了30.8mW的超荧光输出,泵浦斜效率为28%,光谱3dB带宽为35nm。

The experimental results of a wideband Er^3＋/Yb^3＋ co-doped supertluorescent fiber source based on double- backward single pumping configuration have been reported. By using 980 nm pump source and optimizing the pump power as well as fiber length, an output of 30.8 mW ,28% pump slope efficiency and 35 nm 3 dB bandwidth has been achieved at 1550 nm band with only 1m ErEr^3＋/Yb^3＋ co-doped fiber.
