Abstract
Three dimensional (3D) Fourier modal methods, namely aperiodic rigorous coupled wave analysis (aRCWA) and the 3D bi-directional mode expansion and propagation method (BX3) have been recently developed and applied as the efficient and robust frequency-domain simulation tools for modeling both modal and propagation characteristics of advanced photonic and plasmonic nanostructures. In this paper, particularly, after a brief review of types of plasmonic waveguides, we report on several novel types of 3D plasmonic waveguides, especially those of the dielectric-loaded surface-plasmon waveguide (DLSPW) type. In particular, such novel types as hybrid guides, call hybrid dielectric plasmonic slot waveguides (HDPSW), being able to effectively combine strong field confinement with reasonable propagation lengths, are presented and discussed, based on the results of our numerical 3D simulations, in terms of geometrical dispersions, propagation characteristics, and the trade-offs between losses and localization. Using our methods, optical properties of various configurations of such waveguide structures have been numerically analyzed, confirming that these elementary structures represent very promising building blocks for future advanced functioning plasmonic devices.
