Graphene photonic crystals have been attracting increasing attention due to their distinctive properties. In this work, the multichannel filtering performance of a one-dimensional graphene photonic crystal structure is theoretically investigated in the optical communication band. The graphene photonic crystal composed of a stack of alternating layers of dielectric material with high refractive index and graphene sheet. The influence of several structural parameters on the filtering performance of this structure was analyzed using the transfer matrix method. It is shown that the channel number and channel spacing of the multichannel filter can be adjusted by changing the period number and the dielectric constant and thickness of the high refractive index material. The multichannel filtering properties of this graphene structure have potential applications in wavelength division multiplexing systems.
