A novel interconnection structure that is capable of transferring surface plasmon energy between two distanced metal-dielectric-metal waveguides is proposed. A numerical analysis indicates that the power transferring efficiency of the proposed structure approaches 88.5% for one millimeter of interconnection length. The main mechanism of the proposed interconnector is governed by Fabry-Pérot resonance and a multi-mode interference effect in the junction layers. A physical analysis based on the mechanism for designing an optimized structure is also provided, which could be used to modify the proposed structure.
