一种宽带光纤喇曼放大器的设计

A Design Method of Broadband Fiber Raman Amplifiers

在PTDS(photonictransmissiondesignsuite)仿真平台上,对宽带光纤喇曼放大器(FRA)的设计及泵浦源对增益的影响进行了研究。提出了一种宽带FRA的设计方法及增益控制方法,进而设计了增益起伏小于1dB、1dB带宽为80nm的S波段宽带FRA,并且通过增益控制方法可以使FRA的增益灵活地改变。

Design of the broadband fiber Raman amplifier(FRA) and the effect of pump on the gain were researched on the base of photonic transmission design suite(PTDS),which is a simulation platform for optical transmission system emulation.A design method of broadband FRA and a method used to control the gain was put forward.Furthermore we designed a broadband FRA for band S whose gain fluctuation is less than 1 dB and 1 dBbandwidth reaches 80 nm by means of the method.We can change the gain easily.
