摘　　要：报道了利用增益开关分布反馈半导体激光器、Ｆ－Ｐ光学滤波器及掺饵光纤放大器研制成光孤子源的研究工作。光孤子源性能稳定，输出的超短光脉冲重复频率为２．５ＧＨｚ，脉宽２４ｐｓ，谱宽０．１４ｎｍ，时间带宽积０．４１９，平均输出光功率２．４ｍＷ。The studies on an optical soliton source which is prepared using a gain -switched DFB laser, a F-P optical filter and an Er-doped fiber amplifier are reported.The characteristics of the soliton souorce are stable, and the repetition rate, the pulse width and the spectral width of the ultrashort optical pulses generated by the soliton source are 2.5 GHz,24 ps and 0.14 nm,respectively,resulting in the product of time and bandwidth of 0.419.The average optical power of 2.4 mW is obtained.
