| 摘 要： | 对啁啾光栅的时延波动进行了详细的分析，建立了时延波动的简易模型和光栅的滤波函数。大量实验和计算表明，光纤光栅的时延纹波周期在0．01～0．1nm之间，并且在光纤光栅的阻带内，时延纹波周期随波长增大而逐渐增大。利用薛定谔方程对时延波动对系统的影响进行了仿真，得出了时延波动对系统的影响不仅与波动大小有关，而且还与时延波动周期有关，并用实验进行了验证。

| Abstract: | The delay ripple of chirped FBG is analyzed in detail. A simple physical model and function of filter are set up about chirped FBG (CFBG). A numerical simulation of grating delay ripple has been done using Schrodinger equation and compared with experiment. The research shows that the system degradation depends on the period and amplitude of delay ripple. The period of CFBGs′ delay ripple is 0.01～0.1 nm indicated through a lot of experiments. The amplitude of delay ripple must be less than 15 ps in order to assure eye opening penalty less than 0.5 dB. |
