基于模隙限制的一维光子晶体耦合谐振腔光波导（1-D PC-CROW）与传统的周期性缺陷结构相比，具有降低泄漏损耗的可能性。然而，到目前为止，还没有研究基于模隙限制的一维PC-CROW的传输特性。在本文中，我们评估的结构依赖性的群速度和泄漏损耗的1-D PC-CROW使用的3-D矢量有限元法周期性波导分析。通过研究一维PC-CROW的色散关系，我们发现这种一维PC-CROW可以同时实现小的群速度和低的泄漏损耗。
One-dimensional photonic crystal coupled resonator optical waveguide (1-D PC-CROW) based on mode-gap confinement has a possibility to reduce leakage losses compared with conventional 1-D PC-CROW constructed by placing defects periodically. However, transmission characteristics of 1-D PC-CROW based on mode-gap confinement have not been investigated so far. In this paper, we evaluate structural dependence of group velocity and leakage losses of 1-D PC-CROW by using the 3-D vector finite element method for periodic waveguide analysis. We show that such 1-D PC-CROW can realize small group velocity and low leakage losses simultaneously by investigating dispersion relationships of 1-D PC-CROW.
