Abstract
We report a numerical study of plasmonic waveguides that localize light in two dimensions at a cross section of with the propagation length of 38 μm. By varying the geometrical parameters, strong mode confinements (range from to ) are achieved with controllable propagation distance (44.68–40.988 μm), and mode size below has been demonstrated for the first time. Furthermore, a cross-index-modulation mechanism is proposed to explain the strong field localization behavior, providing guidelines for future waveguide designs.
