| 摘 要： | 采用行波解法求解了将非线性偏振旋转控制机构作为强度滤波元件接入滤波控制光纤孤子系统的非线性薛定谔(NLS)方程,得到了近似形式的解析解,并得到了孤子振幅、中心位置、相位的演化方程,在此基础上研究了孤子系统的稳定性问题和孤子系统中由于滤波器带来的非孤子成份等问题.

| Abstract: | The NLS equation with the NPR effect is solved by means of the travelling-wave method and the approximate analytical solution is derived.At the same time soliton ampititude,center position,phase transmission equations are derived. Moreover ,soliton stability in the NPR system and non-soliton part caused by filtering are discussed. |
