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。
The interaction between in-phase and anti-adjacent adjacent soliton pulses under the influence of intra-pulse Raman scattering effect is studied. The effect of the interaction between solitons on the timing jitter and the intra-pulse Raman scattering effect on the soliton frequency shift influences. The results show that under the influence of Raman scattering effect, the periodic clutter of in-phase ground state soliton pulses is destroyed in the pulse. The two soliton pulses are always in a repulsive state after a collision, and the phenomenon of self-frequency shift after the collision is obvious ; The effect of the inversion soliton pulse is weaker, both soliton pulses shift towards the falling edge. The introduction of nonlinear gain can effectively control the interaction between solitons, restrain the self-frequency shift effect and stabilize the soliton transmission.
