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 …

This article reviews recent progress leading to the generation of optical vortex beams. After
introducing the basics of optical vortex beams and their promising applications, we …

Modal decomposition of light has been known for a long time, applied mostly to pattern
recognition. With the commercialization of liquid-crystal devices, digital holography as an …

The angular momentum of light can be described by positions on a higher-order Poincaré
sphere, where superpositions of spin and orbital angular momentum states give rise to laser …

Customizing the output beam shape from a laser invariably involves specialized optical
elements in the form of apertures, diffractive optics and free-form mirrors. Such optics require …

A quantitative analysis of optical fields is essential, particularly when the light is structured in
some desired manner, or when there is perhaps an undesired structure that must be …

In this work, we mainly investigate the propagation of the superimposed field of Laguerre–
Gaussian and Hermite–Gaussian solitons in nonlocal nonlinear Schrödinger equation. The …

Metasurfaces have recently entered the realm of quantum photonics, enabling manipulation
of quantum light using a compact nanophotonic platform. Realizing the full potential of …

A simple method for generating a Laguerre–Gaussian (LG) mode optical vortex beam with
well-determined handedness in a single-frequency solid state laser end-pumped by a ring …

Exciton-polariton condensation is regarded as a spontaneous macroscopic quantum
phenomenon with phase ordering and collective coherence. By engineering artificial …
