摘要
在周期性集中放大的全光孤子通信系统中存在增益和损耗;除了自发辐射引起的时间抖动,还有拉曼耦合引起的时间抖动。本文利用平均孤子模型,通过微扰方法,研究了反常色散区光纤中自发辐射噪声(ASE),尤其是光子和声子耦合导致的拉曼噪声引起的亮孤子到达时间的抖动,并给出拉曼时间抖动的表达式。
In the periodically lumped amplification fiber communication system, the Raman noise exists besides the spontaneous-emission noise. Both spontaneous emission noise of the amplifiers and the Raman coupling noise caused by the time jitter of bright soliton in the anomalous dispersion fiber were studied by means of the perturbation method and the mean soliton, and the expression of the time jitter was given.
