本文对具有π/6对称性的双芯空气-石英微结构光纤的耦合系数进行了数值分析。计算是基于微结构光纤的耦合模理论的特别适合的应用。这种方法与其他三种技术，超模法，光束传播法和等效光纤模型进行了比较，并被证明是非常有效的计算。我们的研究使我们能够推导出一个公式，根据波长，间距和光纤结构的孔径耦合系数的核心分离。(C)2009年美国光学学会
In this paper, we present a numerical analysis of the coupling coefficients in dual-core air-silica microstructured optical fibers with pi/6 symmetry. The calculations are based on an especially fitted application of the coupled mode theory for microstructured optical fibers. This method is compared with three other techniques, the supermode method, the beam propagation method and the equivalent fiber model, and is shown to be very computationally efficient. Our studies enable us to derive a formula linking the coupling coefficients to core separation according to the wavelength, the pitch and the hole diameter of the fiber structure.
