本文利用解析和数值分析的方法分析了线性光纤光栅消啁啾的方法 ,给出光纤光栅参数的理论值 ;分析了耦合系数按反高斯函数变化的啁啾光纤光栅的色散 ,并利用它对增益开关分布反馈半导体激光器的输出脉冲进行消啁啾。数值分析和理论分析基本一致。
In this paper, the method of dechirping of linear FBG is analyzed by means of analytical and numerical analysis. The theoretical value of the FBG is given. The dispersion of the chirped FBG whose coupling coefficient varies according to the inverse Gaussian function is analyzed. Switching output feedback semiconductor laser output pulse cancellation chirp. Numerical analysis and theoretical analysis are basically the same.
