“…The destructive quantum interference is implemented by using a strong coupling laser beam to induce split upper states in a 3-level atom so that the absorption transition from the ground state to the upper states can be exactly cancelled at resonance [2]. It was soon recognized that it is also possible to observe EIT-like effects by using classical optical systems, in which destructive optical interference of two paths inhibits the resonance absorption in a similar way.…”

We theoretically show that it should be possible to demonstrate Electromagnetic-Induced-Transparency-like (EITlike) effects in the visible range by using ultra-compact plasmonic micro-ring resonators with μm 2 order foot print. By using the finite-difference time-domain (FDTD) numerical method and the coupled mode theory (CMT) collaboratively, the transmission intensity, phase, and group delay spectra of the coupled plasmonic ring resonators are theoretically calculated with the inclusion of metallic loss and dispersion through the Drude model. The interference induced transmission peak can be successfully achieved through suitable design of the plasmonic ring resonator structure.

“…Electromagnetically induced transparency (EIT) is the quantum interference effect produced by the interaction between the coherent electromagnetic field and atomic level system 1 . When a coherent electromagnetic field acts on a pair of transition levels in dielectric atoms, the medium absorbs most of the incident field at its resonance frequency.…”

A classical structure for a U-shaped metasurface exhibiting a wideband and large angle electromagnetically induced transparency (EIT) effect in the terahertz range is proposed. One horizontal and two vertical strips, which represent the bright and dark modes, respectively, are created for the U-shaped structure. The finite integration time domain (FITD) and equivalent circuit method are compared with the EIT result. The EIT effect is affected by the length of the vertical bar and by the distance from the vertical bar to the symmetry axis. The results show that the asymmetry of the main structure in the x and y axes makes it easier to achieve the EIT effect. In addition, by changing the incident angle, the EIT effect always exists until the angle of the incidental electromagnetic wave is 85 degrees. These results have many potential applications for terahertz filtering, large-angle switching and sensors.

“…The electromagnetically induced transparency (EIT) [1] is a phenomenon in which the originally opaque medium becomes transparent under certain resonant electromagnetic fields. It has been observed for a long time, applied in ranging from non-linear optics [2], slow light and optical storage [3,4].…”

The proposed graphene metasurface of composite structures of multi‐band and wide‐band transparency windows was investigated by the finite‐difference time‐domain method. The authors discussed a structure which consisted of graphene ribbons and TiO2–SiO2 layer which was sandwiched in between two lithium fluoride dielectric slabs. An electromagnetically induced transparency (EIT) window could be found and tuned gently by the width of lithium fluoride dielectric slabs. Furthermore, an improved structure of air groove in the graphene ribbon was designed. The result showed that a wide‐band EIT window was obtained and tuned by the width and thickness of air groove. The existing research shows that the graphene ribbon is bright mode and LiF slabs are dark mode. These results can find potential applications for many areas such as multi‐band wavelength slow‐light devices, active plasmon switching, infrared invisibility and optical sensing.
