【摘要】 通过研究群速度色散(GVD)和自相位调制(SPM)的相互作用,得到啁啾脉冲在单模光纤的正、反常色散区的啁啾演变规律,并进行了数值分析,结果表明:在正色散区可实现脉冲压缩,形成暗孤子;在反常色散区,可形成亮孤子。更多还原

【Abstract】 In this paper, by taking into account the interaction between GVD and SPM, the chirp evolution of the chirp pulse in the normal and anomalous dispersion regime is obtained analytically and numerically, the results show that the chirp pulse can be compressed and dark soliton can be formed in normal dispersion regime, soliton transmission can be achieved in anomalous regime.更多还原
