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 high repetition rate ultrashort optical pulse generation technology is one of the key technologies in high speed optical time division multiplexing (OTDM) systems. However, the pulse generated by a typical ultrashort pulse source is often not narrow enough, so the optical pulse must be compressed to satisfy High-speed optical communication system requirements. Using a 360 m DDF, the successful output from the Regenerative Mode-Locked Fiber Laser (RMLFL) was centered at 1546 nm with a repetition rate of 10 GHz and pulse widths of 5.40 ps and 4.60 ps, respectively, and thermal insulation Compression is a small pedestal pulse with pulse widths of 1.93 ps and 1.71 ps with compression factors of 2.80 and 2.69, respectively. The light pulse obtained by this method of adiabatic soliton compression has better quality and can be used in 160 Gb / s optical time division multiplexing system.
