Abstract

We first investigate a graphene based 1D plasmonic photonic crystal (PPC) composed of a graphene sheet deposited on an SiO2 grating whose grooves are filled with air by using finite-element method (FEM) software (COMSOL Multiphysics). The dispersion effect of SiO2 is considered in the simulation, and we show that this effect significantly affects the transmission spectrum of the proposed PPC. The transmission spectrum shows a stop band in the mid-infrared region, which is blueshifted by increasing the Fermi energy level of the graphene sheet. However, the transmission spectrum is not affected by variation of the ambient temperature. To achieve a temperature-tunable 1D graphene-based PPC, we propose that the graphene sheet be placed on a grating composed of InAs semiconductor material. Our results confirm that the stop band in the proposed structure can be easily tuned with temperature and moves to higher frequencies by increasing the ambient temperature. Moreover, we introduce a defect into the temperature-tunable PPC to obtain a temperature-tunable Fabry–Perot microcavity. It is demonstrated that the resonance defect mode is easily controllable by changing the temperature and the Fermi energy level.
