TE-mode propagation properties of the coupled planar Kerr-like nonlinear waveguides

For the first time, a closed form expression of coupled Kerr-like nonlinear planar waveguides is derived for both guided and surface waves. The wave propagation properties along the Kerr-like nonlinear waveguides are investigated analytically. The results show that the propagation properties depend on the permitted transmission powers and the initial excitation conditions. All the possible solutions can co-exist in the waveguide structures without mode-coupling.
