Abstract

The dispersion relations of TE-polarized nonlinear guided waves (NGWs) in a symmetrical slab configuration (linear slab embedded between two identical media with a Kerr nonlinearity) are investigated in detail. Among even and odd NGWs the waveguide can support also NGWs, revealing an asymmetrical field pattern. The excitation of these NGWs requires a minimum guided power flux indicating a bifurcation of the corresponding dispersion curves.
