摘　　要：对无初始啁啾高斯脉冲在普通单模光纤中的传输特性及线性啁啾光纤光栅的色散补偿特性进行了理论分析和数值模拟。结果表明 ,光纤的色散导致了传输脉冲的展宽 ,线性啁啾光纤光栅能够实现对展宽脉冲的良好补偿 ,啁啾光栅时延曲线的平滑度和线性度都是影响其色散补偿性能的重要因素。本文对啁啾光纤光栅的制作及其在色散补偿中的应用有一定的指导意义。WT5”BZ]:Transmission characteristics of non chirp original Gaussian optical pulse in standard single mode fiber and dispersion compensation characteristics of linearly chirped fiber gratings have been analyzed theoretically and simulated numerically.Our results show that,optical pulses will be broadened due to dispersion,and linearly chirped fiber gratings can compensate for the broadened pulses perfectly.The linearity and smoothness of the time delay curve for a linearly chirped fiber grating are two key issues for its dispersion compensation characteristics.Our analysis is helpful for fabrication of chirped fiber gratings and its applications for dispersion compensation.[WT5”HZ]
