摘　　要：基于微环谐振腔FWM(四波混频)效应产生的OFC(光频梳)可实现多波长光源和光孤子传输、存储等,能很好地满足光通信网络的要求。对基于微环谐振腔的OFC已有大量的实验报道,但是理论研究却有些不足。文章介绍了目前两种微环谐振腔OFC的理论分析方法,即NCME(非线性耦合模方程)和非线性LLE(Lugiato-Lefever方程),对这两种方法的优缺点进行了比较分析。结果表明,LLE由于其计算速度快,更适合用于基于微环谐振腔的超宽带OFC的理论研究。Optical Frequency Combs (OFC)generated on the basis of Four-Wave-Mixing (FWM)effects in micro-ring resona-tors can be used in multi-wavelength light sources and soliton transmission and storage,well satisfying the requirements of op-tical communication networks.Up to now,there have been large amounts of experiment reports published about such OFC, but their theoretical studies are comparatively scarce.This paper summarizes several latest theoretical analysis methods for mi-cro-ring resonator-based OFC,including Nonlinear Coupling Mode Equation (NCME)and nonlinear Lugiato-Lefever Equation (LLE),and makes comparative analysis of their advantages and disadvantages.The results show that nonlinear LLE is more suitable for the theoretical study of micro-ring resonator-based ultra-wideband OFC thanks to its fast computation speed.
