In this work, the analysis and demonstration of a plasmonic effect of slot rectangular waveguide is presented. The waveguide is made up of a silicon (Si) core, a silicon dioxide (SiO₂) substrate, and a layer of gold (Au) around core at a distance. Parameters like the mode-effective area (MEA) and the confinement factor (CF) is studied using Finite Element Method (FEM). 900 nm is the obtained ideal distance (M_g) for placing metal to all edges of the core. The obtained MEA and CF values were ~0.44 µm² and ~86.75 % respectively at this distance. Applications for a plasmonic slots rectangular waveguide include coupler, resonator, filter, and sensing.
