The generation of ultra-short optical pulses with high repetition rate is one of the key technologies for high-speed optical time division multiplexing systems. However, the pulses directly generated by ordinal ultra-short pulse sources are usually not narrow enough. To meet the demand of high-speed optical communication systems, the pulses should be compressed. Using a 360 m dispersion decreasing fiber, 5.40 ps and 4.60 ps pulses with the repetition rate of 10 GHz and central wavelength of 1546 nm generated from a regeneratively mode-locked fiber laser (RMLFL) are adiabatically compressed into soliton pulses with pulse-width of 1.93 ps and 1.71 ps, respectively. The compression factors are 2.80 and 2.69, respectively. With a high quality and a small pedestal, the compressed solition pulse can be applied to 160 Gb/s optical time division multiplexing system.
