提出了一种实验上可行的，通过光学谐振腔内多通道参量下转换过程直接产生多色连续变量对纠缠频率梳的方案，腔内增益介质为周期极化的准相位匹配的钽酸锂（ LiTaO3）一维光学超晶格。通过连续变量纠缠判据证明了每个通道中产生的每对参量光之间是相互纠缠的。讨论了对纠缠频率梳的纠缠特性随系统参数的变化。此方案在量子通信网络中有着一定的应用前景。

We propose a scheme to produce continuous-variable( CV) pair-entanglement frequency comb by non-degenerate optical parametric down-conversion in an optical oscillator cavity in which a multichannel variational pe-riod poled LiTaO3 locates as a gain crystal. Using the CV entanglement criteria,we prove that every pair generated from the corresponding channel is entangled.The characteristics of signal and idler entanglement are discussed.The CV pair-entanglement frequency comb may be very significant for the application in quantum communication and computation networks.
