摘要

分析了具有反共振反射的蜘蛛网包层塑料空芯光纤在1.3 μm波段的损耗特性及其与结构参数的关系。将光纤包层等效为周期性多层膜，用渐近转移矩阵法进行数值模拟。为优化光纤结构参数，分析了包层层数N，高折射率层厚度d2和高、低折射率比值n2∶n1对损耗的影响。计算结果表明，随着N的增加，损耗首先快速下降最后达到一个固定值；模式损耗随d2的增加呈线形增大趋势，n2∶n1越大，反共振波长处的损耗越低。在此基础上，用模拟退火优化算法对空气层厚d1和纤芯半径rco进行了最优化求解。最后，用以上求得结构参数的优化组合即N=3，d2=2.648 μm，n2∶n1=1.49∶1.0，d1=3 μm和rco=100 μm，计算得到最低损耗是0.449 dB/km。

Abstract

Loss characteristics of antiresonant reflecting plastic optical fiber with cobweb structural cladding and its relationships with the structural parameters are analyzed in the wavelength 1.3 μm. The cladding of this optical fiber is equivalent to periodical multilayer films and numerically simulated by asymptotic transfer matrix method. The effects of the number of alternating layers N, the thickness of highindex layer d2 and index contrast n2∶n1 on the loss characteristics are analyzed to optimize the structural parameters. The numerical simulation results show that the mode loss decreases rapidly in the first and reaches a fixed value in the last as the N increases; the mode lesses increase linearly as the d2 increases; the larger the n2∶n1, the lower the loss at the anti resonant wavelength. On that basis, the thickness of the air layers d1 and the radius of the hollow core rco are optimized by simulated annealing optimization algorithm. Finally, by using above optimal combination of the structural parameters N3, d2=2.648 μm, n2∶n1=1.49∶1.0, d1=3 μm and rco=100 μm, the lowest loss calsulated is 0.449 dB/km。
