Abstract
We conducted a numerical analysis on the cutoff conditions for long-range surface plasmon-polariton in plasmonic strip waveguides at λ = 1.55 μm. Several aspects related to the technological process of realization of the waveguides have been considered. The joint effects of dielectric asymmetries between upper and lower claddings and layering of the strip metallic core in affecting propagation parameters are highlighted.
