Abstract

The hybridization of the plasmonic and guided modes in the case of one-dimension photonic crystal based on Bragg mirror terminated by a corrugated metal film has been demonstrated theoretically. The simulations have showed that the hybrid plasmonic-photonic mode is characterized by low broadening due to redistribution of the electric field intensity between photonic mode and surface plasmon polariton. It was found that the Q-factor and the polarisation sensitivity of these modes are about 144 and 25, respectively, that is 3 times greater than for surface plasmon polariton exciting in similar structure without Bragg mirror.

摘要

理论上已经证明了在基于由波纹金属膜终止的布拉格镜的一维光子晶体情况下，表面等离激元模式与导模的杂化。模拟结果表明，由于光子模式和表面等离激元极化激元之间电场强度的重新分布，混合的等离激元 - 光子模式具有低展宽特性。研究发现，这些模式的品质因数和偏振灵敏度分别约为144和25，这比在没有布拉格镜的类似结构中激发的表面等离激元极化激元的相应值大3倍。
