摘　　要：光纤参量放大器(Fiiber optical parametric amplifier,FOPA)对信号光会产生增益和和延时的作用。在增益边带处的延时会出现频谱很窄的峰值。光纤的零色散波长沿光纤随机波动会对增益边带处的慢光延时有显著影响,使得延时的结果与固定零色散波长的情况有很大的不同。零色散波长的波动会使原来不产生增益峰值的信号波长处也出现延时的峰值,这个峰值在另一个增益边带处。两个延时的峰值处延时都具有较大的延时量,它们随零色散波长波动的波动范围变化。另外,通过优化参量放大器的参数,可以降低零色散波长波动对延时的影响。FOPA has a gain effect on signal light as well as delay. There is a narrow delay peak on one of the gain sideband. The zero-dispersion wavelength fluctuation of fiber has a significant influence on the gain of the gain sideband, causing it different from the non- fluctuation ease. A delay peak appears on the other sideband of gain spectrum because of the zero-dispersion wavelength fluctuation. The delay is very large on both peaks, varying from the range of zero-dispersion wavelength fluctuation. Moreover, efforts are taken to reduce the influence of zero-dispersion wavelength fluctuation by optimizing the parametric of FOPA.
