Paper Abstract

By means of numerical simulation we investigate vortex solitons comprised of coupled pulses with phase singularity under conditions of second harmonic generation. They are usually known for their low stability. We carefully examine homogeneous or inhomogeneous media. Our principal interest is to obtain a stable two-component bullet at normal dispersion. We demonstrate that such bullet can form if spreading tendencies compete with the proper focusing waveguide geometry.
