We construct optical beams in free space with robust skyrmionic structures in their
polarization fields, both in the electric spin vector for near-circular fields and in the …

Abstract The Ince-Gauss beams, separable in elliptic coordinates, are studied through a ray-
optical approach. Their ray structure can be represented over a Poincaré sphere by …

The Lorenz-Mie scattering of a wide class of focused electromagnetic fields off spherical
particles is studied. The focused fields in question are constructed through complex focal …

Structured light beams, such as optical vortices, vector beams, and non-diffracting beams,
have been recently studied in a variety of fields, such as optical manipulations, optical …

Spatiotemporal optical vortices (STOVs) are short pulses that present a vortex whose axis is
perpendicular to the main propagation direction. We present analytic expressions for these …

A novel type of discrete basis for paraxial beams is proposed, consisting of monomial
vortices times polynomials of Gaussians in the radial variable. These bases have the …

An analytic extension to the nonparaxial regime of the full-Poincaré (FP) beams is
presented. Instead of the stereographic mapping used in the paraxial case, these FP fields …

Complete bases that are useful for beam propagation problems and present the distinct
property of being spatially confined at the initial plane are proposed. These bases are …
