摘　　要：研究了用于多通道色散补偿器的取样啁啾光纤光栅时延抖动问题,分析了产生时延抖动的腔效应及抑制时延抖动的切趾技术,分析、比较了切趾前后取样啁啾光纤光栅的时延抖动情况,研究结果表明:取样啁啾光纤光栅的时延抖动与其折射率包络调制形成的外腔效应有关,与取样调制形成的多腔效应无关,对取样啁啾光纤光栅进行包络切趾能够有效地抑制时延抖动。The dispersion ripples of sampled chirped fiber gratings(SCFG) used for multi- channel chromatic dispersion compensation are investigated. The cavity effect causing time delay ripples and the apodization of SCFG depressing the dispersion ripples are all analyzed. The reflection spectrum and the time delay of different apodized sampled chirped fiber gratings are calculated and compared. The results indicated that the time delay is dependent on the extra- cavity effect of SCFG and the time delay can be suppressed by properly apodized SCFG.
