A hybrid plasmonic waveguide and associated methods are disclosed. In one example, the electronic device includes combining an electromagnetic wave propagating in a waveguide with a high refractive index and a surface plasmon from a metal surface to create a hybrid plasmon wave in a low refractive index material separating the dielectric waveguide and metal surface. In selected examples, surface mounted hybrid plasmonic waveguides are shown. In selected examples hybrid plasmonic waveguides embedded in glass interposers are shown.
