摘要

目前,掺铒光纤放大器(edfa)有限的带宽限制了波分复用(WDM)系统和光网络的设计。由于增益谱的高度结构化,可用带宽被限制在20nm以下。使用增益均衡滤波器(gef),增益带宽可以扩展到35到40 nm之间。使用gef很难进一步增加增益带宽。

Ultra Broadband Fiber Amplifiers in 1.5~1.6μm Region
The design of wavelength-division-multiplexed (WDM) systems and optical networks is currently constrained by the limited bandwidth available from erbium-doped fiber amplifiers (EDFAs). The usable bandwidth is limited to be less than 20 nm because of the highly structured gain spectrum. With gain equalization filters (GEFs), this gain bandwidth can be extended to between 35 and 40 nm. It is difficult to further increase the gain bandwidth withGEFs.
