In this paper, a novel T-shaped plasmonic metal-insulator-metal (MIM) splitter with one input and two outputs is proposed, which uses simple stacked Bragg reflectors placed on both the left and right branches. Simulation results show that the resonance wavelengths of the surface plasmon polaritons (SPPs) can be effectively controlled and guided along the desired direction with high confinement by properly designing the parameters of the structure, such as the refractive index of the dielectric, the period and the number of dielectric modulations N. Moreover, the splitting ratio is found to be adjustable by tuning the value of N.
