    We describe the principle of operation of a new class of optical devices operating in quadratic non-linear media that mix wave front topological charge dislocations nested in focused light beams and produce certain patterns ...
  • Impact of imbalancing in the self-splitting of beams with nested vortices into solitons in quadratic nonlinear crystals 

    Molina Terriza, Gabriel; Pérez Torres, Juan; Torner Sabata, Lluís; Soto-Crespo, J M (1998-12)
    Article

    We address the existence and instability of bright vortex solitary waves in quadratic non-linear media under conditions for Type II second-harmonic generation and study in detail the effects introduced by the presence of ...
  • Solitary-wave vortices in quadratic nonlinear media 

    Pérez Torres, Juan; Soto-Crespo, J M; Torner Sabata, Lluís; Petrov, D V (1998-02)
    Article
    Open Access
    We find families of vortex solitary waves in bulk quadratic nonlinear media under conditions for second-harmonic generation. We show that the vortex solitary waves are azimuthally unstable and that they decay into sets of ...

    We find families of optical bright, vortex solitary waves in bulk quadratic nonlinear media under conditions for type II second-harmonic generation. We study the main properties of the families of solitary waves, including ...
