Simple model for spatial optical solitons in planar waveguides.
We use a variational method to develop a simple model for the steady-state behavior of self-trapped beams that have recently been observed in nonlinear planar waveguides. The model allows us to study the transition from two-dimensional to three-dimensional self-trapping as power levels increase and also to investigate the effect of saturation on these beams.
