源啁啾所致光脉冲的压缩特性

Compress characters of source chirp induced light pulses

摘要: 用付理叶变换法从理论上分析了正常色散区域中群速度色散(GVD)和自相位调制度效应(SPM)对光纤中光脉冲传输的影响.结果表明负的源啁啾脉冲在传输过程中能够得到压缩,正的源啁啾导致啁啾脉冲频谱展宽,自相位调制也能使光脉冲压缩但效果较差.

Abstract: Second order dispersion and self-phase modulation in the normal-dispersion region of single-mode fibers are analyzed by means of Fourier-transform algorithm.It is shown that negative source chirps can be compressed owing to normal GVD, and that SPM degrades pulse compression.
