摘要
本文研究了色散管理光纤中超短光脉冲的压缩效应 .对于两种不同的色散管理光纤 ,分析了脉冲压缩机制和效果 .发现总色散为零和总色散不为零的色散管理光纤对超短光脉冲压缩都有较大的压缩比 ,而后者比前者所需最佳纤长缩短一半 .当考虑高阶色散和高阶非线性项效应时 ,发现脉冲压缩质量有所下降 。
The effect on pulse compression in dispersion managed fibers is studied.The higher pulse compression ratios are obtained in both zero total dispersion fibers and nonzero total dispersion fibers.The optimum fiber length of the latter is about half of the former.When higher order dispersion and higher nonlinear effects are considered,the quality of compressed pulse becomes worse.The destructive effect in the dispersion managed fiber of nonzero total dispersion is more serious.
