In the last 10 years, freeform optics has enabled compact and high-performance imaging
systems. This article begins with a brief history of freeform optics, focusing on imaging …

Structured light is derived from the ability to tailor light, usually referring to the spatial control
of its amplitude, phase, and polarization. Although a venerable topic that dates back to the …

The fermionic Hubbard model (FHM) describes a wide range of physical phenomena
resulting from strong electron–electron correlations, including conjectured mechanisms for …

Vector beams, and in particular vector vortex beams, have found many applications in recent
times, both as classical fields and as quantum states. While much attention has focused on …

The modulation and projection of patterns are the cornerstones of spatially structured-light
three-dimensional (3D) imaging. However, an overview of this field is lacking. This paper …

A phase-only hologram applies a modal transformation to an optical transverse spatial mode
via phase encoding and intensity masking. Accurate control of the optical field crucially …

The review covers publications concerned with propagation of laser beams through
turbulent media described by the Kolmogorov theory and generalizations thereof to describe …

Liquid crystals are nowadays widely used in all types of display applications. However their
unique electro-optic properties also make them a suitable material for nondisplay …

Abstract Diffractive Optical Elements (DOEs) are indispensable tools across numerous
technological domains due to their capacity to manipulate light with sophistication and …

We investigate the spin angular momentum (SAM) of double-index cylindrical vector beams
in tight focus. Such a set of beams is a generalization of the conventional cylindrical vector …
