摘　　要：运用分步傅里叶方法,对色散补偿光纤中的双孤子进行振幅调制,观察孤子对之间相互作用及传输规律的影响。通过数值模拟,直观地反映其变化及传输规律,并对数值结果进行分析。结果表明,在不同的振幅值调制下,减小孤子对之间的相对振幅,孤子间的相互作用明显减弱,即振幅较小的孤子比振幅较大的孤子波形更稳定,进而发现,减小孤子间的相对幅度是抑制孤子间相互作用非常有效的手段。The amplitudes of the double solitons in the dispersion compensating fiber are modulated by the fractional Fourier method,and the effects on the interaction and transmission between double solitons are observed.The change and transmission law are illustrated with numerical simulation,and the numerical results are analyzed.The results show that under different modulation of amplitude,when the relative amplitude of soliton pairs is reduced,the interaction between solitons is obviously weakened,that is,the waveforms of the solitons with the smaller amplitudes are more stable than those with larger amplitudes.Furthermore,it is found that reducing the relative amplitudes between solitons is a very effective way to suppress the interaction between solitons.
