本文提出了一种计算微结构光纤漏模和导模的边界积分法。该方法收敛速度快，可以处理大量(数百个)任意几何形状的夹杂。实芯和空芯光子晶体光纤均可有效处理。我们证明了对于具有密集夹杂的大系统，边界积分法的计算强度明显小于多极子方法。这在空芯带隙引导光纤的情况下尤其重要。我们通过将其应用于几个具有挑战性的问题来展示该方法的多功能性。
A boundary integral method [1] for calculating leaky and guided modes of microstructured optical fibers is presented. The method is rapidly converging and can handle a large number of inclusions (hundreds) of arbitrary geometries. Both, solid and hollow core photonic crystal fibers can be treated efficiently. We demonstrate that for large systems featuring closely spaced inclusions the computational intensity of the boundary integral method is significantly smaller than that of the multipole method. This is of particular importance in the case of hollow core band gap guiding fibers. We demonstrate versatility of the method by applying it to several challenging problems.
