Vortex evolution in parametric wave mixing
Petrov, D V; Molina Terriza, Gabriel; Torner Sabata, Lluís (1999-04)
Article
Accés obertWe investigate the evolution of vortex wave front dislocations in multiple-wave second-harmonic generation processes in quadratic nonlinear media. Vortices nested in finite-size host beams are shown to nucleate and to ... -
Vortex nucleation and evolution in parametric wave mixing
Molina Terriza, Gabriel; Torner Sabata, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertWe predict a variety of new phenomena, that includes the spontaneous nucleation of multiple vortex twins, vortex rotation and drift, vortex-antivortex interaction and annihilation, and formation of quasi-aligned patterns ... -
Vortex revivals with trapped light
Molina Terriza, Gabriel; Torner Sabata, Lluís; Wright, E M; Garcia Ripoll, Juan José; Perez García, Victor M. (2001-10)
Article
Accés restringit per política de l'editorialWe predict that vortex dipoles nested in light beams trapped in graded-index media can undergo closed Berry trajectories, yielding periodic vortex annihilations and revivals along the light-propagation direction. The vortex ... -
Vortex streets in walking parametric wave mixing
Molina Terriza, Gabriel; Torner Sabata, Lluís; Petrov, D V (1999-07)
Article
Accés restringit per política de l'editorialThe combined effects of diffraction and Poynting vector walk-off in second-harmonic generation with pump beams that contain screw phase dislocations is addressed for what is believed to be the first time. We predict the ...
