摘　　要：从描述飞秒光孤子传输的高阶非线性薛定谔方程出发,采用对称分步傅里叶变换对方程进行数值求解,模拟了飞秒孤子在光纤通信系统中的传输演化特性。结果表明,合理地配置光纤系统,可以极大地改善孤子的传输演化特性,降低飞秒孤子间的相互作用,从而飞秒孤子在密集色散管理光纤系统中能够很好地传输。Starting from the higher-order nonlinear Schrodinger （NLS） equation expressing the {emtoseeond solitons＇ transmission, the evolution properties of the femtosecond solitons in optical fiber communication system are studied by making use of symmetrical slit-step Fourier numerical method. It is shown that the transmission properties of the solitons are improved greatly and the interaction of the femtosecond solitons decreases when the solitons are transmitting in the fiber collocated appropriately. Thus. the femtosecond solitons can transmit in dense dispersion-managed fiber system primely.
