摘　　要：随着光通信的飞速发展,扩大光纤放大器的增益带宽成为亟待解决的问题.然而,目前常规光纤放大器的增益带宽满足不了通信容量的需求,这给光通信发展带来严峻的挑战.该文简要介绍了掺Bi光纤、Bi/Er共掺光纤和量子点掺杂光纤等超宽带放大方面的最新研究成果,展望了超宽带放大材料的未来研究方向.With the rapid development of optical communications, expanding the gain bandwidth of fiber amplifiers has become an urgent problem to be solved. However,the present gain bandwidth of conventional fiber amplifiers cannot meet the needs of communication capacity, thus bringing serious challenges to the speed and capacity of optical communication. This study briefly introduces the latest research achievements of broadband amplifiers based on Bi-doped fiber, Bi/Er co-doped fiber and quantum dot-doped fiber. And the future researches of ultra-broadband amplifying materials are prospected as well.
