摘要
在色散缓变光纤中,采用群速色散参量以指数方式衰减的理论模型,用分步傅立叶方法数值模拟皮秒脉冲在色散缓变单模光纤中的传输,计算和分析了预啁啾对色散缓变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,发现加入预啁啾,可以使皮秒脉冲得到更好的压缩.
In optical fibers with slowly decreasing dispersion,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 an initial chirp is added on pulses in optical fibers with slowly decreasing dispersion.
