银纳米线有序阵列的光偏振的理论研究

Optical Polarization of Ordered Silver Nanowire Arrays:Theoretical Investigation

报道了组装在氧化铝模板中的银纳米线有序阵列光偏振的数值计算结果.进一步分析了阵列在可见—红外波段上显示光偏振的原因.通过适当选择纳米线的直径与间距,可以获得较大的消光比和较小的插入损耗。

We report the numerical calculation results of ordered silver nanowire arrays embedded in anodic alumina membrane (AAM). Furthermore, the reason of optical polarization of the arrays in the visible and infrared wavelength regions is analyzed. To provide the optimal parameters for the design of nanowire grid polarizers at the wavelengths,we can obtain larger extinction ratios and smaller insertion losses by properly selecting the nanowire diameter and spacing.
