摘要
本文分析一种由两层低折射率孔组成的大模场光纤的模式特性.采用多极法和有限元方法数值计算并分析了内层孔与外层孔尺寸变化对光纤基模与高阶模的束缚损耗与弯曲损耗的影响,设计获得了一种具有较高的高阶模和基模损耗比同时允许一定程度弯曲的大模场光纤.结果表明:当内层孔直径为34 μm,外层孔直径为24 μm时,其基模束缚损耗为0.000 17 dB/m,而高阶模束缚损耗为1.39 dB/m;光纤的基模模场面积为2 150.9 μm2,当弯曲半径为1.2 m时,弯曲损耗为0.106 dB/m.
Abstract
The modal properties of large-mode-area microstructured optical fiber with two-ring holes are analyzed. By using the multipole method and finite element method, the influence of inner and out hole sizes on the fundamental mode and higher-order mode losses of the fiber are numerically calculated and analyzed. In addition, a large-mode area microstructured optical fiber is designed with high loss ratio of higher-order mode and fundmental mode as well as allowing for bending at a moderate radius. For the fiber with the inner ring of hole diameters of 34 μm and the outer ring of hole diameters of 24 μm, the fundamental mode loss is 0.000 17 dB/m, whereas the high order mode loss is 1.39 dB/m. The mode area of the fundamental mode is 2 150.9 μm2, and the bending loss at the bending radius of 1.2 m is 0.106 dB/m.
