摘要: This paper presents a two-dimensional (2D) photonic crystal structure based on graphene surface plasmon polaritons (SPP) for terahertz wavelength division multiplexing (WDM) applications. By etching periodic array of equal-diameter cylindrical holes with the same height in ground, SPP effective index profile 2D can be created single gate voltage between and ground. Based this uneven ground structure, multimode interference (MMI) WDM has been demonstrated. Simulation results show that designed device exhibits isolations higher than 17.30 dB bandwidth 0.06 THz at both frequencies.
