We determine the stability of TE1, nonlinear, stationary wave solutions in planar optical waveguides with nonlinear substrate and cladding bounding media. Our numerical scheme involves propagation of the transverse field distribution corresponding to a standing wave solution on the appropriate branch of the nonlinear dispersion curve. The results indicate that large regions on the TE1branches are unstable. Limited results are also given for a TE2branch with a power threshold.
