初始频率啁啾对压缩光脉冲的影响
摘要
采用数值模拟的方法分析了光脉冲的初始频率啁啾对孤子效应压缩器产生的压缩脉冲的影响
发现光脉冲初始频率啁啾对压缩脉冲的品质因子有较大的影响。光脉冲的初始负啁啾越大
压缩脉冲的最大品质因子越小;初始正啾啁越大
压缩脉冲的最大品质因子越大。光纤的损耗对压缩脉冲的质量有较大影响
特别当孤子阶数较小时影响更大
所以光纤的损耗不能忽略。
Abstract
The effects of the initial frequency chirp on soliton-effect pulse compressor are numerically analyzed.We show that the effects of the initial frequency chirp on the pulse quality factor can not be neglected.The larger the negative chirp of the initial opti- cal pulse is
the smaller the largest quality factor of the compressed optical pulse is.con- versely the larger the positive chirp of the initial optical pulse is
the larger the largest quality factor of the compressed optical pulse is.The optical fiber loss plays an impor- tant role on the quality of the compressed optical pulse
especially when the soliton order is small
so the fiber loss can not be casually neglected.
