In this work, we presented micro-ring resonator structures based on slot and hybrid plasmonic waveguides. The slot waveguide is formed by keeping a narrow air gap between two silicon strip waveguides. Whereas, the hybrid waveguide is composed of Metal-Air-Silicon structure, where the E-field is considerably enhanced in the narrow air gap. The transmission spectrum and E-field distribution of these structures are simulated using the finite element method (FEM). Micro-ring resonator based on hybrid plasmonic waveguide shows the best sensitivity of 333.3 nm/RIU. Whereas, slot waveguide based micro-ring resonator showed the best performance in Q-factor and the figure of merits.
