【摘要】 采用抛物平方变迹啁啾光纤光栅,对超高斯脉冲的色散补偿特性进行了理论分析和数值模拟。数值模拟结果表明,光脉冲在普通单模光纤中传输了一定距离后,由于色散的作用,脉冲发生展宽。用抛物平方变迹啁啾光纤光栅进行色散补偿,比高斯型变迹光纤光栅补偿后的脉冲宽腰更窄,峰值功率也更高,但脉冲形状都发生了些畸变,且随着超高斯阶数的增加脉冲峰值功率逐渐增加,达到一定程度后趋于平缓。更多还原

【Abstract】 Theoretical research and numeric model of dispersion compensation of chirped super Gaussian pulses are presented,using chirped fiber grating with the apodization of parabola squared function.It shows that pulses,after transmitting in a fiber length,will become broadened because of dispersion.When using chirped fiber grating with the apodization of parabola squared function,pulses can be compensated with the results that the width of pulses is more narrow and the max-power is higher.compared with using chirped fiber grating with the apodization of Gaussian function.The pulses are distorted after being compensated.The max-power has something to do with the order of Gaussian pulses.更多还原
