A 93, 033826 (2016) http://uvadoc.uva.es/handle/10324/25963 Nonlinear interfaces separating two diffusive Kerr-type media exhibit dual switching between total internal reflection and transmission. This property is found within a weakly nonlocal regime when both a nonparaxial treatment of the problem and a full two-dimensional model for carrier diffusion are assumed. The theoretical model is shown to predict an effective cubic-quintic nonlinearity with competing terms that produces such property. The validity of the analysis is contrasted with a full set of numerical simulations. application/pdf eng American Physical Society info:eu-repo/semantics/openAccess Helmholtz solitons in diffusive Kerr-type media info:eu-repo/semantics/article SI
