Because of the extensive exponential using of graphene in optoelectronic devices, it is necessary to control its optical properties. One of the effective ways of creating strong electromagnetic fields in a small area of space is graphene surface Plasmon’s. In this paper, by using Graphene-Gold Nano Photonic Crystal, surface Plasmon’s were created in the visible region. Also graphene adsorption and extinction of system were investigated. Dependence of the incident light angle on parameters such as extinction of system was investigated and by choosing the angle of 80 the number of graphene layers were optimized. It was found that, for N=1 the value of absorption is 35 percent and for N=8 high absorbance value of system is 80 percent.
