我们从理论上研究了由金纳米球和硅纳米球组成的二聚体的光学性质。在二聚体中的金球的吸收光谱可以显着改变,并表现出明显的Fano配置文件。解析Mie理论和数值模拟表明,Fano轮廓是由入射电场与硅球磁偶极模电场在窄波长范围内的相长和相消干涉引起的。研究了硅球尺寸、硅球间距和激发构型对二聚体光学响应的影响。我们的研究揭示了介电纳米结构中磁偶极模电场的相干特性以及相干场与其他纳米光子结构的强相互作用。
We theoretically investigate the optical properties of dimers consisting of a gold nanosphere and a silicon nanosphere. The absorption spectrum of the gold sphere in the dimer can be significantly altered and exhibits a pronounced Fano profile. Analytical Mie theory and numerical simulations show that the Fano profile is induced by constructive and destructive interference between the incident electric field and the electric field of the magnetic dipole mode of the silicon sphere in a narrow wavelength range. The effects of the silicon sphere size, distance between the two spheres, and excitation configuration on the optical responses of the dimers are studied. Our study reveals the coherent feature of the electric fields of magnetic dipole modes in dielectric nanostructures and the strong interactions of the coherent fields with other nanophotonic structures.
