摘要
研究了脉冲内拉曼散射效应影响下的同相和反相相邻孤子脉冲之间的相互作用,分析了孤子之间的相互作用对定时抖动的影响和脉冲内拉曼散射效应对孤子频移的影响。研究结果表明:在脉冲内,在拉曼散射效应的影响下,同相基态孤子脉冲的周期性离合被破坏了,两孤子脉冲一次碰撞后一直处于排斥状态,并且在碰撞后自频移现象十分明显;反相孤子脉冲的影响则较弱,两孤子脉冲都向下降沿发生偏移。引入非线性增益可以有效地控制孤子之间的相互作用,抑制自频移效应和稳定孤子传输。
Under the influence of intrapulse Raman scattering, the interactions between in-phase and out-phase optical soil tons was investigated, and the impacts of soliton interactions to timing jitter and the impacts of Raman effects to soliton frequency shift were analyzed. It is found that under the influence of Intrapulse Rarnan scattering, the periodic collision of in-phase soil tons is broken, two solitons are apart from each other after one collision, and the self-frequency shift phenomenon is very obvious after the collision. While for out-phase soliton pair, two solitons both shift to the dropping edge and the impacts of intrapulse Raman scattering effects are weaker compared with in-phase soliton pair, A nonlinear gain can be used to effectively suppress soliton interactions and effects of intrapulse Raman scattering, and stabilize the soliton propagation.
