In this paper, guided waves in nonlinear slab waveguides have been accurately studied using finite element method. It is obvious from the results that the design of nonlinear waveguides strongly depends on the power. Power decides the ability of supporting soliton wave through this structure. Our numerical results show that it will support soliton wave at 35 W. The wave propagation properties illustrated here are potentially applicable to investigate signal processing and communication devices composed of nonlinear slab waveguide structures.
