英文摘要	Abstractwe propose a plasmonic bragg reflector (pbr) composed of a single-layer graphene-based silicon grating and numerically study its performance. an external voltage gating has been applied to graphene to tune its optical conductivity. it is demonstrated that spp modes on graphene exhibit a stopband around the bragg wavelengths. by introducing a nano-cavity into the pbr, a defect resonance mode is formed inside the stopband. we further design multi-defect pbr to adjust the characteristics of transmission spectrum. in addition, through patterning the pbr unit into multi-step structure, we lower the insertion loss and suppress the rippling in transmission spectra. the finite element method (fem) has been utilized to perform the simulation work.
