摘要

本文研究了利用OTDM和脉冲压缩技术，利用10ghz DFB-LD产生20ghz超短光脉冲序列。提出了一种新的三级压缩技术，即在正常色散光纤中进行补偿，在正常色散光纤之后对异常色散光纤进行压缩，在梳状色散轮廓光纤中进行压缩。实验得到脉宽为3.3 ps的压缩脉冲，总压缩系数为7.6。该技术对于实现80gb /s OTDM系统非常重要。

20 GHz ultra-short optical pulse source generated by DFB-LD and pulse compression technology

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.
