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.
Compared with the one-order soliton,the high order solitons propagation in the optical fiber is more complex,via numerical solution of the nonlincar Schroinger equalion（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 thai if the third-order dispersion increased, it wilt resuh in new character of the solitons decay, it finally induced higher code error rate.
