In this study, we achieve polarization-insensitive triple plasmon-induced transparency (triple-PIT) at terahertz frequencies using a novel graphene metamaterial comprising block, four squares, and strips. The insensitivity of structure to changes in the incident light’s polarization angle is attributed its high symmetry. expressions nth-order coupled mode theory are derived accurately, theoretical predictions closely align with findings numerical finite-difference time-domain simulations for...

We theoretically and numerically investigate a low-power, ultrafast, dynamic all-optical tunable plasmon induced transparency (PIT) in two stub resonators side-coupled with metal-dielectric-metal (MDM) plasmonic waveguide system. The optical Kerr effect is enhanced by the local electromagnetic field of surface polaritons (SPPs) based on graphene-Ag composite material structures large effective nonlinear coefficient. An ultrafast response time order 1 ps reached because carrier relaxation...
In this paper, low-power and ultrafast all-optical tunable plasmon induced transparency in metal-dielectric-metal (MDM) waveguide side-coupled Fabry-Perot (FP) resonators system with nonlinear optical Kerr medium is investigated both analytically numerically. High tunability window magnitude phase responses obtained when material embedded the MDM waveguide. order to reduce pump intensity, traditional replaced by graphene. A shift of 64 nm central wavelength achieved FP are covered monolayer...
We theoretically and numerically investigated the plasmon-induced transparency (PIT) effect in a single circular split-ring core ring resonator (CSRCRR) side coupled to metal–isolator–metal waveguide, which we can realize PIT window. The transmission line theory mode are used. results (transmission peak varies from 10% 75%) show that window destructive interference between resonance modes CSRCRR. Then, limit of wavelength detuning two CSRCRR is studied. This work provides new structure shows...
To develop alternative plasmonic materials for nanophotonic applications, the thickness-dependent optical properties of ultrathin Sr 0.82 NbO 3 (SNO) films deposited on MgO are investigated. As thickness decreases from 10 to 2 nm, film exhibits less metallic, epsilon-near-zero (ENZ) wavelength redshift and higher loss due increased scattering. Nevertheless, thinnest still has a high carrier concentration 22 cm −3 , real part dielectric functions all is than zero in near-infrared (NIR)...
Overcoming the challenge of preparing high-transparency and low-resistivity thin films is great significance for development indium-free transparent electrodes. In present work, high-quality Mg, Al, Ga co-doped ZnO (MAGZO)/Cu/MAGZO multilayer are deposited on glass by magnetron sputtering. The effects Cu layer thickness (
The proposed slow light waveguides are based on photonic crystal imposed by a selective altering the locations of holes adjacent to line defect. Normalized Delay-Bandwidth Product keeps around 0.37 for all cases.
