摘　　要：利用色散补偿光纤（ＤＣＦ）及色散位移光纤（ＤＳＦ）压缩重复频率为２．５ＧＨｚ的增益开关量子阱ＤＦＢ半导体激光器出射的光脉冲，将光脉冲由５３．８ｐｓ压缩至２．５ｐｓ，而后利用色散渐减光纤将２．５ｐｓ的光脉冲进一步压缩至０．８３ｐｓ。In this paper, optical pulses generated from gain switched MQW DFB semiconductor laser with repetition the rate of 2.5GHz are firstly compressed from 53.8ps to 12ps using dispersion compensation fiber. Then, the 12ps pulses are compressed to 2.5ps using soliton effect compression in dispersion shifted fiber. Finally, the pulses of 2.5ps are compressed to 0.83ps in dispersion decreasing fiber.
