In this paper, a new structure is proposed to improve the performance of graphene modulators. The performance of the graphene modulators has generated so far depends on the polarization of incident light, so that these modulators modulate TM polarization better than the TE polarization. Responsible for this performance difference is the anisotropy of graphene, which has caused the performance of the common modulators is strongly dependent on polarization. In this paper by adding a graphene layer to the waveguide side-wall, in addition to graphene existing in the top of waveguide, Performance dependency of the modulator to polarization has greatly disappeared. The simulation results indicate that, in addition to eliminating the sensitivity of the modulator to the polarization of light, the overall performance of the modulator has also been significantly improved.

Keywords: graphene, graphene modulator, polarization sensitive, anisotropic electric permittivity
