Abstract: The transmission spectra in the terahertz frequency range of a one-dimensional photonic crystal structure with ordered layers of graphene particles placed in a defect layer are studied. Graphene particles and graphene wires connecting them form two-dimensional arrays whose chemical potential can be varied by the magnitude of applied electric potential. The possibility of controlling the transmission coefficient in the mini-zone associated with the defect mode of the photonic crystal in the range of 0.05–0.7 is shown.

Keywords: photonic crystal, microresonator, graphene particles, transmission spectrum, tuning.
