  We study the giant Goos-Hanchen shift obtained from an Airy beam impinging on
a nonlinear interface. To avoid any angular restriction associated with the
paraxial approximation, the analysis is based on the numerical solution of the
nonlinear Helmholtz equation. We report the existence of non-standard
intermittent and oscillatory regimes for the nonlinear Goos-Hanchen shifts
which can be explained in terms of the competition between the critical
coupling to a surface mode of the reflected component of the Airy beam and the
soliton emission from the refracted beam component.
