Through meticulous theoretical investigation, we have demonstrated the realization of highly efficient stimulated Brillouin scarttering (SBS) in a silicon graphene strip waveguide. The optimized waveguide configuration through the Fermi level of graphene on the silicon waveguide, yields remarkable performance metrics. Specifically, we achieved brillouin gain of 9.54w-1m-1 by tuning the Fermi level of graphenere, which presents significant advancements in nonlinear optical performance.
