“…The transformation and coupling of SAM and OAM are the basis for the second scheme [ 127 , 128 ]. This occurs in media that are nonuniform and anisotropic, such as q-plates [ 129 ]. Q-plates have a spatially shifting optical axis and change the circular polarization state from left to right or right to left.…”

Herein, we have discussed three major methods which have been generally employed for the generation of optical beams with orbital angular momentum (OAM). These methods include the practice of diffractive optics elements (DOEs), metasurfaces (MSs), and photonic integrated circuits (PICs) for the production of in-plane and out-of-plane OAM. This topic has been significantly evolved as a result; these three methods have been further implemented efficiently by different novel approaches which are discussed as well. Furthermore, development in the OAM detection techniques has also been presented. We have tried our best to bring novel and up-to-date information to the readers on this interesting and widely investigated topic.

“…Beam shaping is a prerequisite for most photonics applications [1][2][3][4][5]. Starting from an input laser beam with known optical features the shaping should be able to generate an output laser illumination with prescribed characteristics.…”

In the framework of the scalar theory of diffraction a surface-pixeled convergent lens for arbitrary amplitude and phase modulation along the depth of focus is introduced. This complex diffractive lens is computer-generated from an exact solution of the inverse focal shaping problem obtained by using the Fresnel diffraction integral. The spatial multiplexing technique of double-phase method is employed to encode the complex diffractive lens into a phase optical element that can be dynamically implemented with a commercial liquid-crystal spatial light modulator. The optical surface of this lens, capable of generating not only a single axial focus but also multiple parallel foci, has neither linear nor rotational symmetry but phase jumps from one pixel to another. In addition to intensity shaping, the introduced lens provides simultaneous control over the phase of light along the depth of focus, which can be very attractive for improving and/or developing photonic applications related to the interaction of coherent laser beams with matter.

This Letter demonstrates optical vortex lattices based on holographic polymer-dispersed liquid crystal (HPDLC) films. The fabrication method uses a phase-only reflective spatial light modulator with numerically calculated phase profiles loaded on it to simplify multi-helical-wave interference. The beam profiles of the diffraction beams are simulated using the Fourier transform and compared with experimental results. The topological charges of the 1st-order diffraction beams reconstructed from the HPDLC films are examined using a Michelson interferometer.
