The Kerr spatiotemporal self-focusing of light pulses in a planar glass waveguide was demonstrated. A numerical model based on nonlinear Schrodinger equation was used to observe the focusing of light pulses in planar waveguides and compare the nonlinear behavior in different dispersion regimes. The results of numerical simulations suggested that spatial self-focusing occured in all three dispersion regimes but temporal contraction was found to occur only in the case of anomalous dispersion.
