“…Surface plasmon polaritons (SPPs) supported at the metal-dielectric interface have the ability to confine electromagnetic waves in the subwavelength range and overcome the classical diffraction limit [4,5]. Therefore, plasma-induced transparency (PIT), an optical effect similar to EIT, has attracted much attention due to its remarkable advantages and wide practical applications [6]. In general, there are two schemes to achieve PIT: bright-dark mode coupling (direct coupling) [7][8][9][10][11] and bright-bright mode coupling (indirect coupling) [12][13][14][15][16].…”

In this paper, two parallel graphene strip structures are adopted to achieve tunable plasma-induced transparency (PIT) sensors in the terahertz band. Both graphene bands act as bright modes, and a PIT window appears due to the weak hybridization between them. A Lorentzian oscillation coupling model is fitted to the simulation results of the proposed structure by the finite-difference time-domain (FDTD) method and is in good agreement with the simulation results. The performance of the PIT system can be controlled by tuning the geometrical parameters of the structure. In addition, the resonant frequency of the PIT window can be dynamically adjusted by changing the chemical potential and carrier mobility of the graphene strips. When the chemical potential of graphene increases from 0.2 eV to 1 eV, the amplitude modulation depth of the PIT window (2.832 THz, 3.684 THz, and 4.386 THz) can reach 92.39%, 96.14%, and 90.4%, respectively. Furthermore, due to its dispersion characteristics, the realized PIT window has a sensitive response to the surrounding medium, and the sensitivity can be as high as 1.25 THz/RIU. This PIT effect-based graphene microstructure has important implications for the future design of terahertz modulators, optical switches, and ultrasensitive sensors.
