    The characteristics of TE0 modes in a waveguide with two identical Kerr type nonlinear claddings and a linearuniform core are analyzed. Both theoretical analysis and numerical examples give the sameresults. For the focusing case,with increasing modal refractive index, the maximum valueof core field gradually decreases. At a definite optical power, when the modal refractiveindex at the core-cladding interface is equal to refractive index of core, the core fieldbecomes uniformly 'platform-like', while the cladding field rapidly reduces. As the modalrefractive index continually increases, the maximum field enters into the twocladdings,while the field profile in the core changes to concave. Curves (focusing anddefocusing cases) are given for field distributions, relations between modal index andpower,ratio of core power to total power versus total power, relations between'platform'height and core index, relations between 'platform' and core width, and so on.
