We quantify the power and bandwidth variations with the applied magnetic field and locate a broadening bandwidth area in the fast-light region. We optimize the azimuth angle of input light, i.e. 45°-linearly polarized light, to significantly reduce the required magnetic induction for the status transition by 71%. The results of the MO-MRR scheme support the implementation of the MO-induced tunable integration chip for microwave photonic
