Plasmon Induced Transparency

AbstractThe plasmon-induced transparency (PIT), which is destructive interference between the superradiation mode and the subradiation mode, is studied in patterned graphene-based terahertz metasurface composed of graphene ribbons and graphene strips. As the results of finite-difference time-domain (FDTD) simulation and coupled-mode theory (CMT) fitting, the PIT can be dynamically modulated by the dual-mode. The left (right) transmission dip is mainly tailored by the gate voltage applied to graphene ribbons (stripes), respectively, meaning a dual-mode on-to-off modulator is realized. Surprisingly, an absorbance of 50% and slow-light property of 0.7 ps are also achieved, demonstrating the proposed PIT metasurface has important applications in absorption and slow-light. In addition, coupling effects between the graphene ribbons and the graphene strips in PIT metasurface with different structural parameters also are studied in detail. Thus, the proposed structure provides a new basis for the dual-mode on-to-off multi-function modulators.

Plasmon Induced Transparency

We demonstrate the realization of plasmon induced transparency (PIT) in a nanostructure composed of silver nanobars and a silver nanodisk. The optical properties of the planar metamaterials have been investigated theoretically in the paper. The classical coupled harmonic oscillator model demonstrates the PIT phenomenon in a nanodisk–nanobar system. Additionally, double PIT response is observed when two nanobars are located in proximity to the silver nanodisk. The PIT window wavelength and bandwidths can be efficiently tuned by controlling the geometric parameters such as the lengths of nanobars and the coupling distances between the nanodisk and nanobars. Moreover, the transparency window shows highly sensitive response to the refractive index of the environmental medium. A high figure of merit up to 15.5 of the asymmetrical system for refractive index sensing is achieved. The tunability of the PIT may have potential application on slow light and highly integrated optical circuits.
