色散缓变光纤中超短光脉冲的绝热压缩
Adiabatic Compression of Ultra-Short Pulses in Fibers with Slowly Decreasing Dispersion
摘要
报道了色散缓变光纤中超短光脉冲压缩效应的实验结果.采用两段长度分别为100 m和500 m的色散缓变光纤,成功地将分布反馈激光器输出的4.4 ps光脉冲压缩到1.1 ps和830 fs,脉冲压缩比分别为4.0和5.3.研究还发现,色散沿纵向变化较慢的光纤有利于脉冲的进一步压缩,理论分析与实验结果一致.
Abstract
The adiabatic compression of ultrashort pulses from a DFB laser operating at 1550 nm in the fibers with slowly decreasing dispersion (FSDD) is investigated. High quality soliton compressions from 4.4 ps down to 1.1 ps in a 100 m FSDD and from 4.4 ps down to 830 fs in a 500 m FSDD are obtained. Furthermore, the results show that FSDD with more slowly decreasing can benefit to the pulse compression. Theoretical analyses are in good agreement with experimental results.
