摘要
采用椭圆空气孔的八边双芯结构,设计了两种分别以碲、SF6玻璃作为基质材料的双芯光子晶体光纤(PCF)。基于Maxwell方程理论推导了PCF的反射系数和透射系数,得出了消光比的计算模型。实验结果表明:碲玻璃的制作双芯PCF能够表现更小的消光比,达到-54d B,更适合于x、y偏振光分离。
Using the 8-side double-core structure of elliptical air hole, this paper designe s two kinds of two-core photonic crystal optical fiber （PCF）. Based on Maxwell equation, the reflection coefficient and transmission coefficient of PCF are derived and the calculation model of extinction ratio is obtained. The experimental results show that the PCF can perform a smaller extinction ratio, which is more suitable for the separation of x and y polarized light.
