This paper describes experiments concerned with pulse train generation from initially modulated cw light in an anomalous dispersion decreasing fibre. We have obtained stable contrast trains of subpicosecond pulses with a repetition rate in the range 100 – 300 GHz and demonstrated generation of an optical comb spectrum with a –20-dB width of up to 80 nm. A method has been proposed for reconstructing an unknown dispersion profile of a longitudinally nonuniform fibre by comparing experimental data and numerical simulation results.

色散减小光纤中高频脉冲序列的产生：利用实验数据测量纵向非均匀光纤

本文描述了与在异常色散减少光纤中从最初调制的 cw 光产生脉冲序列有关的实验。我们已经获得了重复率在 100 – 300 GHz 范围内的亚皮秒脉冲的稳定对比度序列，并展示了产生 –20-dB 宽度高达 80 nm 的光梳光谱。通过比较实验数据和数值模拟结果，提出了一种重建纵向非均匀光纤未知色散分布的方法。
