摘　　要：研究了不同速率的两束光脉冲同向传播时,互相位调制造成的对相邻孤子互作用的影响。在传输一长串孤子的同时,相邻的另一信道的特定位置存在光脉冲,该脉冲改变孤子串中相应位置孤子的相位,从而改变孤子间互作用力的性质,达到控制孤子互作用的目的。通过数值计算,对该方法进行了分析。结果表明,光脉冲对孤子串的控制作用取决于其幅度,与相位无关。最后,介绍了该方法的潜在用途。Studied soliton interaction under the influence of cross-phase modulation when two light with different group velocity copropagated.As a word coposed of solitons porating,a soliton at the place in neighbor channel changed the phase of soliton at the same place,as a result changed the character of interaction in order to control soliton interaction.This way is studied numerically.It shows that the state of optical pulse control solitons denpend on its amplitude and independ on its phase.Finally,we point out the use of this way.
