Three-dimensional optical vortices in nonlinear Bessel waveguides
Carlos F. Sánchez, Humberto Michinel, Boris Malomed +2
We explore the formation, stability, and propagation dynamics of light bullets carrying orbital angular momentum (vorticity) in Bessel-structured nonlinear graded-index waveguides.…
Guided vortex bullets
Carlos F. Sánchez, Ángel Paredes, Humberto Michinel +2
By means of the variational method and numerical simulations, we demonstrate the existence of stable 3D nonlinear modes, viz. vortex ``bullets'', in the form of pulsed beams carryi…
Photonic Nambu-Goldstone bosons
Miguel Ángel García-March, Ángel Paredes, Mario Zacarés +2
We study numerically the spatial dynamics of light in periodic square lattices in the presence of a Kerr term, emphasizing the peculiarities stemming from the nonlinearity. We find…
