Plasmon-induced anti-transparency modes in metasurface
Applied Nanoscience, 2019We investigate plasmon-induced anti-transparency (PIAT) modes with a metallic metasurface on a dielectric substrate through the finite-element method. Multiple spectral splits are achieved by breaking the symmetry of square-ring resonators. The asymmetry of the structure is attained by incorporating cuts in the rings and increasing displacement of cuts

Plasmon induced transparency in a dielectric waveguide
Applied Physics Letters, 2011A classical effect of electromagnetically induced transparency (EIT) is demonstrated in a dielectric slab waveguide at visible frequencies. Two nano-sized elliptical silver particles are placed inside the waveguide core layer, and their localized plasmonic resonances are utilized to obtain bright and dark states.

Plasmon-induced transparency in terahertz planar metamaterials
Optics Communications, 2015A planar metamaterial structure with plasmon-induced transparency effect in terahertz region is proposed and systematic numerical study is presented in this paper. The metamaterial structure is comprised of two different spilt-ring resonators in the same plane.

Modes conversion due to plasmons induced transparency
Physics Letters A, 2019Abstract We investigate simulated and theoretically the optical properties of the metamaterial, composed of two bigger split ring resonators and one smaller split ring resonator in unit cell. We observe the magic phenomena that one mode B is inhibited from strong to weak then disappears while another mode A appears and becomes stronger and stronger ...

Dynamically tunable plasmonically induced transparency by planar hybrid metamaterial
Optics Letters, 2013We design and numerically analyze a dynamically tunable, plasmonically induced transparency (PIT) planar hybrid metamaterial (MM) in a near-infrared regime, which combines the near-field coupling effect into dynamic MM. The embedded position of tunable material in dynamic MM is optimized. Thermal-tunable VO(2) stripes are filled in the cut-out slots as

Multispectral plasmon-induced transparency in hyperfine terahertz meta-molecules
Journal of Physics: Condensed Matter, 2016We experimentally and theoretically demonstrated an approach to achieve multispectral plasmon-induced transparency (PIT) by utilizing meta-molecules that consist of hyperfine terahertz meta-atoms. The feature size of such hyperfine meta-atoms is 400 nm, which is one order smaller than that of normal terahertz metamaterials.

Plasmonic induced transparency in graphene oxide quantum dots
Quantum Dots and Nanostructures: Growth, Characterization, and Modeling XV, 2018The absorption due to phonon vibrations in graphene oxide quantum dots (GO-QDs) has been modified by localized plasmons induced by Ag nanoparticles (NPS). The interference of phonons and plasmons results in coherent interaction that leads to the formation of "dark states" and "coherent population trapping" related to Fano like effect.

Tailoring mode interference in plasmon-induced transparency metamaterials
Journal of Physics D: Applied Physics, 2018We proposed an approach to tailor the mode interference effect in plasmon-induced transparency (PIT) metamaterials. Through introducing an extra coupling mode using an asymmetric structure configuration at terahertz (THz) frequencies, the well-known single-transparency-window PIT can be switched to dual-transparency-window PIT.

Lasing oscillation condition in plasmon-induced transparency waveguide
International Photonics and Optoelectronics Meetings (POEM), 2013Plasmonic waveguide with detuned resonators is studied in plasmon-induced transparency window. Gain coefficient is quadratic with detuning in lasing oscillation condition. Spectra in amplification regime below lasing threshold have large group delay, high transmittance and narrow linewidth. A straight-forward biosensing application is demonstrated.

Tunable plasmon-induced transparency with graphene-sheet structure
Modern Physics Letters B, 2016We investigate theoretically and numerically the tunable plasmon-induced transparency (PIT) phenomenon in graphene-sheet system in infrared range. We show that when surface plasmon polaritons (SPPs) propagate along a monolayer graphene sheet with two detuned side-coupled resonators, the PIT-like transmission spectra of SPPs appear.
