对采用法布里－珀罗腔和正常色散光纤联合消啁啾进行了理论和实验上的研究。实验得到了啁啾小于孤子形成临界值，重复频率为５ＧＨｚ、脉宽为１６．２ｐｓ的超短光脉冲，并对消啁啾后的超短光脉冲进行了孤子传输实验。 Theoretical and experimental studies on the joint chirp cancellation using Fabry-Perot cavity and normal dispersion fiber are carried out. The experiment results show that the chirp is smaller than the critical value of soliton formation, the repetitive frequency is 5GHz and the pulse width is 16.2ps. The experiment of the soliton transmission is performed on the chirped ultrashort optical pulse.
