本文利用摄动微扰法对单模光纤中传输的基阶亮孤子和暗孤子进行了研究。结果表明,暗孤子应用于光通信系统作为信息载体,其有比亮孤子更好的特性。
In this paper, we study the first order bright solitons and dark solitons transmitted in single-mode optical fibers by perturbation perturbation method. The results show that dark solitons are used in optical communication systems as information carriers, which have better characteristics than bright solitons.
