We theoretically show that it should be possible to demonstrate Electromagnetic-Induced-Transparency-like (EIT-like) effects in the visible range by using ultra-compact plasmonic micro-ring resonators with μm 2 order foot print. By using the finite-difference time-domain (FDTD) numerical method and the coupled mode theory (CMT) collaboratively, the transmission intensity, phase, and group delay spectra of the coupled plasmonic ring resonators are theoretically calculated with the inclusion of metallic loss and dispersion through the Drude model. The interference induced transmission peak can be successfully achieved through suitable design of the plasmonic ring resonator structure.
