【摘要】 本文较为全面的阐述了近几年来国内外对长波段掺铒光纤放大器(L-band EDFA)的研究情况,从设计EDFA最主要的技术关键-铒光纤与泵浦源两方面分析了其工作原理,总结出新的设计思路与方案,并提出了一些新的研究点。同时,也分析、介绍了一些结构新颖的宽带(C+L band)EDFA。更多还原

【Abstract】 In this paper we have aimed our discussions at a survey of the development of L-band EDFA in recent years. Its principles are discussed by analysing EDF and pump source which are the two key technologies. Many novel designs are presented here, as well as some C+L band EDFAs. Several research issues are also proposed in this paper.更多还原
