We investigate and compare the characteristics of the fundamental guided mode sustained by a subwavelength plasmonic slot waveguide for three types of metals: gold, silver and aluminium. This is done in terms of mode effective index, propagation length, confinement and, as the mode under study is quasi-TEM, we also develop a transmission line model that can be useful in the design of optical components making use of slot waveguides.
