In order to suppress the nonlinear effect in such sampled fiber grating extemalcavity semiconductor laser,apodization and interleaved technology have been introducedinto the external sampled fiber grating of such laser.

为了抑制可调谐取样光纤光栅外腔半导体激光器的非线性效应，在该激光器的外部光栅中引入了间插技术和切趾技术。

The research shows that the delay linearity of fiber grating without apodization is bad and the curve of dispersion is not smooth, so it's difficult for this kind of fiber grating to be used in dispersion compensation system.

研究表明，未经过变迹的啁啾光纤光栅的时延曲线的线性度很差，色散曲线抖动也较大，很难作为色散补偿器来加以应用。

We find in study that FSD performs like a band-pass filter with deconvolution function as the high-pass filter and apodization function as the low-pass filter. They together determine the filtering characteristics of FSD.

作者研究发现，退卷积过程等效于一个带通滤波器，其中高通滤波器是退卷积函数，低通滤波器是切趾函数，滤波器的特性由它们共同决定。
