摘要
高重复频率超短光脉冲产生技术是高速光时分复用(OTDM)系统的关键技术之一,而一般的超短脉冲源直接产生的脉冲往往不够窄,因此必须对光脉冲进行压缩后才能满足高速光通信系统的要求。采用360 m长的色散渐减光纤(DDF),成功将从再生锁模光纤激光器(RMLFL)输出的中心波长1546 nm、重复频率10 GHz、脉宽分别为5.40 ps和4.60 ps的光脉冲,绝热压缩为脉宽为1.93 ps和1.71 ps的小基座孤子脉冲,压缩因子分别为2.80和2.69。利用这种绝热孤子压缩方法得到的光脉冲质量较好,可以用于160 Gb/s的光时分复用系统。
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.
