In this paper, we propose a high-performance refractive-index sensor at a near-infrared band based on a hybrid Tamm structure. The optical properties of this graphene-based hybrid Tamm plasmonic structure are analyzed and investigated by using the transfer matrix method (TMM). Due to the excitation of the guide mode resonance (GMR) and Tamm plasmon polariton (TPP) resonance, the structure can realize multi-channel perfect absorption. This structure can be utilized as a refractive index sensor because the position of the absorption peak is sensitive to the refractive index of the ambient layer. Therefore, we obtain the sensitivity to 950 nm per refractive index unit (nm/RIU) and figure of merit (FoM) of 161 RIU^-1 after studying the performance under different structural parameters. We believe that the proposed configuration is expected to be used to manufacture high-performance biosensors or gas sensor devices and other related applications in the near-infrared band.

基于石墨烯混合Tamm等离子体结构的高灵敏度多通道折射率传感器

在本文中，我们提出了一种基于混合 Tamm 结构的近红外波段高性能折射率传感器。通过使用转移矩阵方法 (TMM) 分析和研究了这种基于石墨烯的混合 Tamm 等离子体结构的光学特性。由于导模共振（GMR）和Tamm等离子体激元（TPP）共振的激发，该结构可以实现多通道完美吸收。这种结构可以用作折射率传感器，因为吸收峰的位置对环境层的折射率敏感。因此，我们获得了每折射率单位 (nm/RIU) 950 nm 的灵敏度和 161 RIU ^-1的品质因数 (FoM)在研究了不同结构参数下的性能后。我们相信，所提出的配置有望用于制造高性能生物传感器或气体传感器设备以及近红外波段的其他相关应用。
