Abstract
The main features of a dielectric-loaded surface plasmon polariton waveguide are analyzed such as mode effective index and propagation length. These parameters are calculated using the finite element method for different metal-polymer pairs while varying the ridge width and thickness. As a performance metric, we employ the 2D figure of merit including two conflicting parameters i.e. mode effective index and propagation length. The results obtained here allow one to identify the parameter range for realizing the dielectric-loaded surface plasmon polariton waveguide and to choose dimension and material of the ridge for subwavelength confinement and moderate propagation loss at telecom wavelengths.
