Strong coupling effect of graphene Tamm Plasmon Polaritons in the terahertz band
A novel one-dimensional graphene-Photonic Crystal(PhC) composite resonant structure is designed, and the strong coupling effect between the terahertz Tamm Plasmon Polaritons(TPP) and Cavity Modes(CM) supported by the Transmission Matrix Method(TMM) is theoretically studied. It is shown that the Rabi splitting energy employed to characterize the coupling strength increases with the decrease of the number of PhC periods. In addition, when changing the thickness of the spacer layer and the cavity, as well as the Fermi level of graphene, the Rabi splitting energy is also affected. Finally, the coupling mode can also be actively adjusted by changing the angle of incidence. When the angle of incidence is between 0° and 60°, the characteristics of the coupling mode are independent of polarization. This work provides a new idea for the study of strong coupling effect.
