　　我们在平面波扩展及超元胞方法的基础上，提出了光子晶体光纤缺陷模的一种详细的计算方法。在此方法中我们利用光子晶体光纤结构的对称性设计算法，有效的降低了计算量和计算耗时。在三角晶格的光子晶体光纤的特定例子中，我们用该方法在其中一个光子带隙中成功获得了缺陷模。

We present a detailed calculation method of defect mode of PCFs based on the plane-wave expansion and supercel method,in which we can make use of the symmetry of the structure of PCFs and reduce the computational consuming.In a specific example for PCFs with a triangular lattice,we obtain successfully a defect mode in one of photonic band gaps.
