本文对具有类EIR色散特性的平面金属等离激元超材料(planar plasmonic metamaterials,PPM)对光学Tamm态及相关激射行为的增强作用进行了研究.我们首先运用传输矩阵方法分析了利用PPM结构的色散来增强光学Tamm态对应模式电磁局域密度的可能性.其次,我们将具有类EIR特性的PPM与一维光子晶体(photonic crystal,PC)合在一起设计了一种平面等离激元超材料-光子晶体(PPM-PC)异质结构.研究发现,通过在电磁局域密度最高的PPM结构中(或附近)加入增益介质,可观察到比通常光学Tamm态更强的激射增强效应及更明显的单色性响应.这些特性使得这种PPM-PC结构有望被应用于低阈值激光器、荧光增强等方面.
In this paper, the enhancement of the Tamm state and the lasing behavior of planar plasmonic metamaterials (PPMs) with EIR-like dispersion properties are studied.We first use the transfer matrix method to analyze the effect of the PPM structure Of dispersion to enhance the optical local density of optical Tamm states.Secondly, we combine a PPM with EIR-like properties with a one-dimensional photonic crystal (PC) to design a planar plasmon Metamaterial-Photonic Crystal (PPM-PC) Heterostructure The study found that by adding a gain medium to (or in the vicinity of) the PPM structure with the highest density of electromagnetic localizations, stronger lasing enhancement than the general optical Tamm state can be observed Effects and more pronounced monochromatic response These characteristics make this PPM-PC structure is expected to be applied to low threshold lasers, fluorescence enhancement and so on.
