Abstract :
Plasmonic waveguides supporting gap surface plasmons (GSPs) localized in a dielectric spacer between metal films are investigated numerically and the waveguiding properties at telecommunication wavelengths are presented. Especially, we emphasize that the mode confinement can advantageously be controlled by the waveguide width and the dielectric spacer thickness and thus allows for straightforward fabrication of highly integrated waveguides by a single lithography step.
