FIG. 1.

Examples of TM modes of a nonlinear slot coupler for (left column) and (right column). The plots show the magnetic component for antisymmetric modes [(a) and (d)], symmetric modes [(b) and (e)], and asymmetric modes [(c) and (f)]. The labels correspond to the points marked in Fig. 2.

FIG. 2.

Total mode power vs propagation constant for the modes of the nonlinear plasmonic coupler. The points [(a)–(f)] correspond to the modes shown in Fig. 1. Point O is the bifurcation point for the asymmetric mode.

Image of FIG. 3.
FIG. 3.

Examples of mode propagation and beating in the plasmonic coupler for different input powers: (a) Linear regime, , (b) intermediate regime, , and (c) nonlinear regime, . The image shows the modulus of the magnetic component.

Image of FIG. 4.
FIG. 4.

Normalized output power vs input power for the excited waveguide of the nonlinear plasmonic slot coupler at the beat length , shown for vanishing and realistic losses.
