A metallic-grating-based interconnection scheme that interconnects two waveguide layers of surface plasmon polaritons (SPPs) is presented. We designed a diffraction grating for radiating light from the SPPs into free space or a homogeneous medium. An efficient receiver grating for receiving the light into SPPs is also explored. Using the well-established finite-element method, the appropriate grating geometry parameters are found. The directional interconnection efficiency is 32.4% for the best case in our numerical analysis.
