All light has structure, but only recently has it been possible to control it in all its degrees of
freedom and dimensions, fuelling fundamental advances and applications alike. Here we …

Our ability to generate new distributions of light has been remarkably enhanced in recent
years. At the most fundamental level, these light patterns are obtained by ingeniously …

Optical phase singularities are zeros of a scalar light field. The most systematically studied
class of singular fields is vortices: beams with helical wavefronts and a linear (1D) singularity …

While in linear optics the subject of structured light has been a fruitful field of both theoretical
and applied research, its development in the arena of nonlinear optics has been …

The ability to design vectorial optical fields with desired properties in different media has a
significant impact on many applications including microscopy, optical trapping …

Recent advances in optical beam shaping have enabled a wide class of structured lights
that follow exotic trajectories, opening many routes for numerous applications. Although the …

An easily accessible approach is proposed to create structured beams with various
quasicrystal structures and polarization distributions based on multi-beam interference. By …

In this article, we show that quasi-phase matching can be accomplished by manipulating
one of the pump beams without any periodic poling. We analyze a simple case wherein one …

A method for the generation of tunable multi-degree-of-freedom rotations of vector beams on
demand along a propagation direction is theoretically proposed. This generation can be …

Designing optical fields with predetermined properties in source-free inhomogeneous media
has been a long-sought goal due to its potential utilization in many applications, such as …
