Abstract :
This paper studies that generation of 20 GHz ultra-short optical pulse series by 10 GHz DFB-LD with OTDM and pulse compression technology. A novel three-stage compression technology is brought forward, including compensation in normal dispersion fiber, compressing in anomalous dispersion fiber followed normal dispersion fiber and in comb-like dispersion profile fiber (CDPF). In the experiment, the compressed pulse of 3.3 ps pulse width was obtained and the total compress factor is 7.6. This technique is important for implementing an 80 Gb/s OTDM system
