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。
There are gains and losses in the all-optical soliton communication system that is periodically focused and amplified; besides the time jitter caused by spontaneous emission, there is time jitter caused by Raman coupling. In this paper, by using the average soliton model, the perturbation method is used to study the spontaneous emission noise (ASE) in the anomalous dispersion fiber, especially the jitter of bright soliton arrival time caused by the Raman noise caused by photon and phonon coupling, Man-hour jitter expression.
