摘要
为了讨论光孤子在色散管理系统中传输的特性,分别模拟了孤子在平均色散为负(反常色散)、正(正常色散)的不同色散深度色散管理系统中演化的情况,结果表明,随着周期色散图色散深度的增大,稳定传输的脉冲峰值功率增大,且脉冲周期性振幅的波动幅度增大,并且发现了亮孤子可以在平均色散为正的光纤系统中传输,但传输质量较差,传输距离有限。
In order to discuss the soliton transmission characteristics in dispersion management system, the following cases that the averaged dispersion of dispersion map is negative (anomalous) and positive (normal) are simulated respectively. The result shows that as depth of dispersion map changes stronger, pulses' peak power and fluctuation of pulses' amplitude become greater, and bright soliton can transmit stably in the averaged dispersion of positive, but transmission quality is poor, transmission distance is limited
