Room-Temperature Amplification of Terahertz Radiation by Grating-Gate Graphene Structures

Physical Review X, 2020
We study terahertz (THz) radiation transmission through grating-gate graphene-based nanostructures. We report on room-temperature THz radiation amplification stimulated by current-driven plasmon excitation.

Tunable Plasmon-Induced Transparency in Dual Hexagonal Resonators With Rotatable Embedded Bar

IEEE Photonics Journal, 2019
In this paper, tunable plasmon-induced transparency (PIT) is achieved in a novel and compact plasmonic system which consists of dual hexagonal resonators with rotatable rectangular bar embedded in resonators and a metal-insulator-metal (MIM) waveguide ...

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.

A High-Sensitivity Graphene Metasurface and Four-Frequency Switch Application Based on Plasmon-Induced Transparency Effects

Photonics
In this paper, we propose the use of a monolayer graphene metasurface to achieve various excellent functions, such as sensing, slow light, and optical switching through the phenomenon of plasmon-induced transparency (PIT).

Symmetry-Engineered Dual Plasmon-Induced Transparency via Triple Bright Modes in Graphene Metasurfaces

Photonics
Dynamical manipulation of plasmon-induced transparency (PIT) in graphene metasurfaces is promising for optoelectronic devices such as optical switching and modulating; however, previous design approaches are limited within one or two bright/dark modes ...
