摘要

摘要:
为了提高品质因子（Quality value， Q ）以增强光与物质的耦合作用，本文提出一种结构简单、工艺制备要求低的介质超材料，它可激发对称保护的连续介质束缚态（bound states in the continuum , BICs）。该介质超材料具有四聚孔组成的平面纳米孔板，通过改变纳米孔的位置，可使对称保护BIC转变为对称保护的QBIC，进而诱导出两个高品质因子 Q 值Fano共振。经计算Fano共振在非对称参数 Δ =3 nm时， Q 值可达到1×e⁶。随后将QBIC和Fano共振的远场辐射分解为不同多极子分量的贡献，基于散射功率和电场矢量分布可以发现，介质超材料在 λ ₁出现高 Q 值Fano共振主要是因为磁四极子和环偶极子的存在，而在 λ ₂出现高 Q 值Fano共振主要是因为环偶极子的存在。最后分析计算了纳米孔边长和纳米孔填充材料对两个Fano共振的影响。本文的研究可以为研究制备高 Q 值光学响应器件提供理论指导。

Abstract:
In order to improve the quality value ( Q ) to enhance the coupling between light and matter. In this paper, a dielectric metamaterial with simple structure, low fabrication requirements was proposed. It can excite symmetric protected bound states in the continuum (BICs). The dielectric metamaterial has a planar nanopore plate composed of tetrameric pores. By changing the position of the nanopores, the symmetrical protection BIC can be transformed into the symmetrical protection quasi BIC(QBIC), and then two high Q value Fano resonances can be induced. Through simulation calculation, the Fano resonance Q value can reach 1×e⁶when Δ =3 nm. Then, the far-field radiation of QBIC and Fano resonance is decomposed into the contributions of different multipole components. Based on the scattering power and electric field vector distribution, it can be found that the dielectric metamaterials λ ₁Fano resonance with high Q value is mainly due to magnetic quadrupole and toroidal dipole, while λ ₂Fano resonance has high Q value is mainly due to the toroidal dipole. Finally, the influence of nanopore side length and nanopore filling material on the two Fano resonances is analyzed and calculated. The research in this paper can provide theoretical guidance for the future research and preparation of high Q value optical response devices.
