We report a numerical study of plasmonic waveguides that localize light in two dimensions at a cross section of 4.2nm×2.1nm with the propagation length of 38 μm. By varying the geometrical parameters, strong mode confinements (range from λ2/3352 to λ2/2557525) are achieved with controllable propagation distance (44.68–40.988 μm), and mode size below 1nm2 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.
