亚波长金属孔阵列的退偏效应

Depolarization induced by subwavelength metal hole arrays

Cyriaque Genet, Erwin Altewischer, Martin P. van Exter, J. P. Woerdman

摘要:

提出了一种基于量子力学的亚波长金属孔阵列退偏理论。我们推导出具有各种对称性(特别是正方形和六边形)的孔阵列在有限直径(如高斯)光束照射下的Mueller矩阵。去极化是由于两个因素的组合引起的:(i)表面等离子体激元沿着阵列表面的传播,(ii)入射光束中波矢量的传播。

英文摘要:

We present a symmetry-based theory of the depolarization induced by subwavelength metal hole arrays. We derive the Mueller matrices of hole arrays with various symmetries (in particular square and hexagonal) when illuminated by a finite-diameter (e.g. gaussian) beam. The depolarization is due to a combination of two factors: (i) propagation of surface plasmons along the surface of the array, (ii) a spread of wave vectors in the incident beam.
