摘要

本文采用考虑拉曼增益的耦合非线性薛定谔方程，利用分步傅里叶方法求解并仿真模拟了光孤子脉冲在不同性质的双折射光纤中传输时的演化过程. 结果表明，拉曼增益可以有效抑制非线性耦合导致的孤子漂移，同时会导致光孤子脉冲峰值在传输时不断增大，产生拉曼放大效应. 拉曼增益也可以有效抑制双折射光纤中传输的相邻光孤子之间的相互作用.

The coupled nonlinear Schrödinger (CNLS) equation including Raman gain has been utilized for birefringence fiber. Evolution process of the optical soliton pulse has been simulated by the fractional Fourier method when the optical soliton pulse transmission in a birefringence fiber has a different nature. Results show that the drift of soliton caused by nonlinear coupling effect can be suppressed by Raman gain, at the same time, the soliton pulse peak in the transmission is enhanced. The interaction between optical solitons can be effectively restrained by Raman gain in the birefringence fiber.
