Abstract

The present invention discloses an all-dielectric metamaterial EIT (electromagnetically induced transparency)-like resonance device. The all-dielectric metamaterial EIT (electromagnetically induced transparency)-like resonance device comprises a planar waveguide and a two-dimensional periodic dielectric resonator; the planar waveguide comprises a first dielectric layer; the two-dimensional periodic dielectric resonator is composed of cuboid dielectric bars which are arranged at the upper surface of the first dielectric layer and are in two-dimensional periodic distribution; the refractive index of the cuboid dielectric bars is greater than the refractive index of the first dielectric layer; the two-dimensional periodic dielectric resonator has a resonant characteristic, so that the two-dimensional periodic dielectric resonator can generate a series of Mie resonance according to the Mie resonant principle; the two-dimensional periodic dielectric resonator has a grating-like effect, so that the two-dimensional periodic dielectric resonator can make incident waves diffracted and coupled with the guided mode of the planar waveguide; and an EIT-like effect can be generated through controlling the interaction of Mie resonance and guided mode resonance. With the all-dielectric metamaterial EIT (electromagnetically induced transparency)-like resonance device of the invention adopted, high-quality factor resonance and high resonance intensity can be achieved, and a high group refractive index can be obtained.

Description

technical field [0001] The invention belongs to the technical field of metamaterials, in particular to a metamaterial EIT (Electromagnetic Induced Transparency) resonance device. Background technique [0002] Metamaterials are artificially designed sub-wavelength periodic resonant structural materials. Because they can obtain properties that cannot be obtained by natural media, they have very important applications in the fields of negative refractive index, invisibility cloaks, sensing, and filtering devices. Compared with metal metamaterials, all-dielectric metamaterials can obtain higher resonance quality factor and resonance intensity due to the absence of metal ohmic loss. [0003] Electromagnetically induced transparency (EIT) is an important physical phenomenon arising from the interference between energy levels in polyatomic systems. This EIT phenomenon has the characteristics of strong dispersion, so it is accompanied by a large group refractive index in this regio...
