摘　　要：针对色散控制孤子系统中孤子幅度、脉宽等参数的动态周期变化特性,采用变分法分析了高速色散控制啁啾高斯准孤子在自陡峭条件下的传输演化特性.对160 Gb/s长距离高速色散控制孤子传输系统的传输特性进行了数值模拟,指出了自陡峭效应对系统的有害性和控制的必要性,对色散控制孤子系统设计具有参考价值.In allusion to periodic dynamic change of the soliton parameters,such as its amplitude and width in dispersion management soliton system,the evolution of the dispersion management soliton system was analyzed in the presence of self-steepening by using variational approach.The performances of long-haul dispersion management soliton transmission system at the rate of 160 Gb/s were numerically simulated.The nocuous influence and the necessarity of management of self-steepening were pointed out.The results have valuable reference for designing the dispersion managed soliton system.
