摘要
在色散沿光纤传输方向线性减小的光纤中,用分步傅里叶方法数值模拟皮秒脉冲的传输,计算和分析了初始啁啾对色散渐减光纤中皮秒脉冲的孤子效应压缩的影响。通过分析脉冲压缩比,最佳光纤长度,压缩后的脉冲峰值功率和脉冲压缩质量的变化,发现加入初始啁啾,可以使皮秒脉冲得到更好的压缩。
In dispersion decreasing fiber, the effect of initial chirp on the quality of soliton-effect compression is analyzed by simulating the transmission of picosecond pulse numerically. By analyzing the change of compression factor, optimum fiber length, peak power of compressed pulse and compression quality, we have found that good compression effect will be obtained if initial chirp is added on pulse in dispersion decreasing fibers.
