中文摘要：
通过环形的夫妇共鸣器洞波导的轻繁殖特征被有限差别的时间域(FDTD ) 系统地分析方法。这种波导由于增加洞尺寸有更多的 minbands，这被发现，与传统的打线的夫妇共鸣器波导相比。当邻近的环形的洞关于 0.00067c 在垂直方向，和组速度被交叉时，轻繁殖的组速度能为进一步的度被减少(c 是在真空的轻速度) 能被获得。
英文摘要：
The light propagation characteristics through the annular coupled-resonator cavity waveguides are systematically analyzed by the finite-difference time-domain （FDTD） method. It is found that this kind of waveguide has more minbands owing to the increasing of the cavity＇s size, compared with the traditional line-typed coupled-resonator waveguide. The group velocity of light propagation can be reduced for a further degree when the adjacent annular cavities are interlaced in the perpendicular direction, and a group velocity about 0.00067c （c is the light speed in vacuum） can be obtained.
