摘要
比较了3种不同色散递减类型光纤构成的马赫-曾德尔干涉仪(MZI)的光脉冲压缩特性.结果表明:考虑高阶效应时,各种色散渐减光纤构成的MZI的脉冲压缩比例较大,脉座能量也大,对数渐减光纤构成的MZI压缩脉冲质量最好;不考虑高阶效应时,也是对数渐减光纤构成的MZI的压缩脉冲质量最好.
The compression characteristics of optical pulse in a Mach-Zehnder interferometer constructed from three different dispersion-decreasing .fibers are compared. The results show that the compression of optical pulse in a Mach-Zehnder constructed from a logarithmic dispersion profile is optimal when high-order effects are not considered. When high-order effects are considered, the compression ratio is relatively large, the pedestal energy increases simultaneously, and the compression of optical pulse in a Mach-Zehnder constructed from logarithmic dispersion profile is optimal.
