摘要:

实验演示和表征的等离子体介导的共振传输通过一个嵌入的起伏的连续薄金属膜垂直入射下。1D起伏被示出为实现空间分辨的偏振滤波,而2D起伏导致空间分辨的偏振无关的传输。而所需的亚微米微结构本身在原则上,以CD般的低成本大规模复制通过注塑成型和压花,本文件演示了预期的传输效果的实验模型的基础上,金属涂层的光致抗蚀剂光栅。研究了共振附近的光谱和角度依赖性,并讨论了表面等离子体所表现出的过量损耗问题

英文摘要:

The experimental demonstration and characterization is made of the plasmon-mediated resonant transmission through an embedded undulated continuous thin metal film under normal incidence. 1D undulations are shown to enable a spatially resolved polarisation filtering whereas 2D undulations lead to spatially resolved, polarization independent transmission. Whereas the needed submicron microstructure lends itself in principle to CD-like low-cost mass replication by means of injection moulding and embossing, the present paper demonstrates the expected transmission effects on experimental models based on metal-coated photoresist gratings. The spectral and angular dependence in the neighbourhood of resonance are investigated and the question of the excess losses exhibited by surface plasmons is discussed
