Abstract: We investigate theoretically the light reflectance of a graphene layerprepared on the top of one-dimensional Si-SiO2 photonic crystal 1DPC. It isshown that the visibility of the graphene layers is enhanced greatly when 1DPCis added, and the visibility can be tuned by changing the incident angle andlight wavelengths. This phenomenon is caused by the absorption of the graphenelayer and the enhanced reflectance of the 1DPC.
