Self-healing of light refers to the ability of a light field to recover its structure after being
damaged by a partial obstruction placed in its propagation path. Here, we will give a …

Structured light has revolutionized optical particle manipulation, nano-scaled material
processing, and high-resolution imaging. In particular, propagation-invariant light fields such …

Caustics are responsible for a wide range of natural phenomena, from rainbows and
mirages to sparkling seas. Here, we present caustics in space-time wavepackets, a class of …

In this paper, we consider the comparative formation of perfect optical vortices in the non-
paraxial mode using various optical elements: non-paraxial and parabolic toroidal vortex …

We extend the established transverse customization of light, in particular, amplitude, phase,
and polarization modulation of the light field, and its analysis by the third, longitudinal spatial …

From a geometric perspective, the caustic is the most classical description of a wave function
since its evolution is governed by the Hamilton–Jacobi equation. On the other hand …

Structured light, also known as tailored light, shaped light, sculpted light, or custom light,
refers to a series of special light beams with spatially variant amplitudes and phases …

We introduce a non-diffracting beam family as a new beam solution of the scalar Helmholtz
equation in Cartesian coordinates whose complex amplitude is mainly described by the …

We report experimental observation and theoretical explanation of novel propagation
regimes for optical beams in an artificial nonlinear material with outstanding photorefractive …

Using angular spectral representation, we demonstrate a generalized approach for
generating high-dimensional elliptic umbilic and hyperbolic umbilic caustics by phase …
