Low-loss electromagnetically induced transparency (EIT) and asymmetric Fano line shapes are investigated in a simple planar silicon dimer resonator. The EIT and Fano effects emerge due to near-field coupling of the modes supported by both the nanoparticles in a dimer structure. Different configurations of the dimer nanostructure are analyzed, which provide distinct EIT and Fano resonances. Furthermore,...
Compared to metallic nanostructures employed in plasmonics, dielectric materials with high refractive index can directly engineer magnetic responses in addition to the electric responses in plasmonic structures. In this work, we have demonstrated that the magnetic-based double Fano resonances can be achieved in the Au-SiO2-Si multilayer nanoshells due to the strong interaction between electric resonances...
