Helmholtz Bright Spatial Solitons and Surface Waves at Power-Law Optical Interfaces
Figure 15
Nonparaxial interaction () between a lower-branch nonlinear surface wave (with ) and a unit-amplitude () soliton in regime 1 (mismatch parameters and ) with . (a) Evolution in of the peak amplitude of the solution. (b), (c), and (d) show the full numerical solution of (5) when the nonlinearity exponent is (surface wave follows interface), 2 (surface wave deflected), and 3 (surface wave destroyed), respectively.
