| 摘 要： | 通过数值求解非线性薛定谔方程,得到了二阶和三阶孤子的传输特性,并和一阶孤子做了比较.对于二阶孤子和三阶孤子间的相互作用做了分析,讨论了三阶色散对高阶孤子相互作用的影响,得出随着三阶色散的增大,会使孤子的衰变具有新的特性,将会导致光孤子通信的误码率加大.

| Abstract: | Compared with the one-order soliton,the high order solitons propagation in the optical fiber is more complex,via numerical solution of the nonlinear Schringer equation(NLSE),the characters of the second-order and the third-order solitons are obtained,and they are also compaired with the one order soliton.The interactions of the second-order and the third-order solitons are analyzed,and the influence of third-order dispersion to high order solitons is discussed,the conclusions are showed that if the third-order dispersion increased,it will result in new character of the solitons decay,it finally induced higher code error rate. |
