    "abstract": "Properties of two pulses propagating simultaneously in different dispersion\nregimes, anomalous and normal, in a Kerr-type planar waveguide are studied in\nthe framework of the nonlinear Schroedinger equation. Catastrophic\nself-focusing and spatio-temporal splitting of the pulses is investigated. For\nthe limiting case when the dispersive term of the pulse propagating in the\nnormal dispersion regime can be neglected an indication of a possibility of a\nstable self-trapped propagation of both pulses is obtained.",
