Broadband X-waves with orbital angular momentum
Miguel A. Porras, Raúl García-Álvarez
We describe the minimal diffraction-free and dispersion-free, superluminal wave packets (X-waves and generic superluminal localized waves) that can carry a given amount of units $m…

Spatiotemporal optical vortex solitons: Dark solitons with transverse and tilted phase line singularities
Miguel A. Porras
Vortex solitons (dark solitons) are described in self-defocusing Kerr media whose phase line singularity is not parallel to the propagation direction, but is perpendicular or tilte…

Exploding paraxial beams, vortex beams, and cylindrical beams of light with finite power in linear media, and their enhanced longitudinal field
Miguel A. Porras
We present a set of paraxial light beams with cylindrical symmetry, smooth and localized transversal profile carrying finite power, that develop intensity singularities when they a…
