Abstract

Surface plasmon polaritons have become a research area of great importance. We present theoretical investigations on the realization of components and Y-splitters for surface plasmon polaritons guided by dielectric-loaded waveguides. The effect of the limited resolution of the fabrication process on the characteristics of fabricated Y-splitters is analyzed. A more efficient and robust configuration of the Y-splitter for surface plasmon polaritons is proposed.
