摘要:
提出一种完美吸收结构,其包含一金衬底层,上方为金圆柱与氧化铝长方柱镶嵌而成的金属/介质混合腔阵列.模拟计算发现:电场主要局域在金圆柱的边缘和氧化铝长方柱内部,该结果表明偶极等离子体共振和等离子体激元腔模式是产生多频带完美吸收的主要机理.该结构制作简单,且其完美吸收具备偏振调控和对周围样品折射率变化高度灵敏,这些特性有望为实现痕量检测提供一种简便方法.
Abstract:
A multispectral perfect absorber is proposed and demonstrated by utilizing a square array of an Al2O3-cuboid intercalated with an Au-cylinderdeposited on an opaque Au substrate.It is shown that the electric field is strongly localized in the corner region of Au cylinder and the inside area of Al2O3 cuboid,namely,the dipolar plasmon resonance and the plasmon cavity mode are the two primary reasons for the occurrence of perfect absorption.Moreover,the absorption is polarization depended and highly sensitive to the refractive index variation of the surrounding sample.These findings could open a simplified alternative approach to achieve the practical trace detection.
