摘要

针对密集排列的聚合物微纳光纤间存在的串扰问题，文章提出采用时域有限差分方法分析两根相交的聚对苯二甲酸丙二醇酯微纳光纤的相交角度、直径、分离距离、偏振模态及波长对串扰的影响。仿真结果表明，串扰随相交角度和分离距离的增大而减小，通常从单模截止直径起，串扰随直径的减小而增大，直到达到一个最大值，然后随直径的减小而减小，X方向偏振模态时串扰较低，波长为1 550 nm时串扰较低。仿真结果为构筑超紧凑结构复杂的光学器件和小型化集成光路提供了较好的指导意义和参考价值。

Abstract

In order to reduce the crosstalk between the densely arranged polymer micro-nano fibers

this paper proposes to analyze the dependence of crosstalk on the intersection angle

diameter

separation

modal polarizations and wavelength of two intersecting polytrimethylene terephthalate micro-nano fibers using the Finite Difference Time Domain (FDTD) method. The results suggest that the crosstalk decreases with the increase of the intersection angle and separation. From the single-mode cut-off diameter

the crosstalk increases with decreasing diameter until reaching a maximum value

and then decreases afterward. Additionally

the crosstalk is lower in the Xdirection polarization and is smaller at the wavelength of 1 550 nm. These results provide good guidance and reference value for the construction of complex ultra-compact photonic devices and miniaturized integrated optical circuits.
