P07 – Low-Cross-Talk Metal-Dielectric-Metal Waveguide Intersections Based on Sodium
We analyzed the transmission properties of two plasmonic waveguides crossing by using numerical simulations. The subwavelength width waveguides are composed of sodiumair-sodium. The crossing structure is composed by a compact cross-shaped resonant cavity with a four-fold symmetry. The results demonstrated the feasibility of using sodium as a low loss material for several applications for nanoplasmonic integrated circuits implementation.
