Tunable plasmon induced transparency with high transmittance in a two-layer graphene structure

Results in Physics, 2021
A dynamically tunable plasmon induced transparency planar structure with double layers hollow-cross graphene array is proposed in this paper. Due to energy oscillating back and forth between two weak hybridized states made up of upper and lower graphene,

Plasmon induced transparency in cascaded π-shaped metamaterials

Optics Express, 2011
We experimentally and numerically demonstrate a planar metamaterial consisting of two asymmetrically positioned π-structures in a single unit that exhibits plasmonic analogue of electromagnetically induced transparency (EIT). Through the coupling of the constituent nanorod elements, the proposed structure enables fine spectral tuning of the EIT-like ...

Plasmonic-Induced Transparencies in an Integrated Metaphotonic System

Nanomaterials, 2022
In this contribution, we numerically demonstrate the generation of plasmonic transparency windows in the transmission spectrum of an integrated metaphotonic device. The hybrid photonic–plasmonic structure consists of two rectangular-shaped gold nanoparticles fully embedded in the core of a multimode dielectric optical waveguide, with their major axis ...

Plasmon-induced transparency in ring-bar meta-atom

AIP Advances, 2018
We introduce an approach for constructing a scalable metamaterial structure, which is composed of a ring and a bar in a unit cell, and supports singular plasmon-induced transparency. The composite multilayered structure consists of coupled meta-atom with

Plasmonic solitons and dromions via plasmon-induced transparency

Journal of Physics: Conference Series, 2016
We propose a method to enhance Kerr nonlinearities and realize low-power gigahertz solitons via plasmon induced transparency (PIT) in a new type of metamaterial, which is constructed by an array of unit cell consisting of a cut-wire and a pair of varactor- loaded split-ring resonators.

Ultraslow long-living plasmons with electromagnetically induced transparency [PDF]

Optics Letters, 2018
We analytically examine propagation of surface plasmon polaritons (SPPs) at a thin metallic film between glass substrate and electromagnetically-induced-transparency (EIT) medium. High-precision and high-resolution in frequency domain provided by EIT paves the way towards plasmonic group velocities reduction even by $4$ orders of magnitude and ...

Electrical Control of Plasmon Resonance with Graphene [PDF]

, 2012
Surface plasmon, with its unique capability to concentrate light into sub-wavelength volume, has enabled great advances in photon science, ranging from nano-antenna and single-molecule Raman scattering to plasmonic waveguide and metamaterials.
