“…Particular interests have been concentrated on the interaction of angular momenta, i.e. spinorbit coupling, which produced marvelous evolutions of light fields such as spin Hall effect of light [55][56][57][58]. These related performances of optical vortices have been introduced into electric beams, atom beams, and even matter wave systems [59][60][61].…”

Vortices arise in many natural phenomena as dark points of total destructive interference. Sometimes they form continuous lines and even enclosed loops with knotted or linked topologies in three spatial dimensions. Since the mathematical topology was introduced into physics, from hydrodynamics, condensed matter physics to photonics, and other modern physical fields, scientists have been exploring the related topological essences of vortex knots; hence, the topology is a forefront topic in different physical systems. Owing to the reliability and observability of light in free space, optical vortex knots and links are the most studied physical topologies. Here, we review some of these developments with a focus on optical vortex knots and links. We first introduce the brief historical perspective and structural properties of optical vortices. Then, we trace the progress on the theoretically constructing, experimentally generating, and characterizing methods of topological light fields. Wherein, we review recent developments of holographic metasurfaces and their applications in generating ultrasmall optical vortex knots. At last, we envision the possible challenges and prospects of topological light fields.

“…In addition to the canonical vortex, the non-canonical vortex can also carry variable OAMs, such as non-symmetric vortex beams [12], [13], helico-conical beams [14], [15], fractional vortex beams [16], [17], Airy vortex beams [18]- [20], Pearcey vortex beams [21], [22] and so on, which have diverse propagation behaviors. The optics vortices can also be modulated [23]- [27]. For example, when the helical phase of an optics vortex is modulated by a cosine function, the beam will gradually split into several main lobes during propagation.…”

The orbital angular momentum (OAM) holography has been developed and experimentally demonstrated capable of holographic multiplexation and high-security encryption. However, the helical phase of an OAM mode can only be encoded into one hologram associated with a target image, and this severely limits the information capacity in practical applications. The modulated orbital angular momentum (MOAM) holography is proposed by imposing multiple modulation phase modes onto one OAM mode. Three essential properties, including the MOAMpreservation, MOAM-selectivity and MOAM-multiplexation are investigated. This method can significantly enhance the holographic information capacity and it has broad prospects for optical encryption and beam manipulations.

“…[21,22] Hence, in the past decade, exploring novel vector fields with remarkable propagating and focusing property was becoming an interesting topic of beam physics. [23][24][25][26] It is well known that light wave is a transverse wave, that is, in free space, its electric vector is perpendicular to the propagation direction. Accordingly, the modulations of SoP mostly devote to engineer light fields with spatially inhomogeneous SoP in the cross-section, including in free space and optical media.…”

Light fields with spatially structured states of polarization (SoPs) are gathering increasing attention because of their potential applications from optical imaging and micromanipulation to classical and quantum communications. Meanwhile, the concepts within structured light fields have been extended and applied to acoustic, electron, and matter waves. In this article, we review recent developments of the SoP modulation of light fields, especially focusing on three-dimensional (3D) modulations on the SoPs of light fields. The recent progress and novel implementations based on 3D spin-dependent separation are discussed. Following the discussions to this physical phenomenon, we then describe recent developments on the vector fields with 3D structured SoP and intensity distributions, namely, 3D vector fields. The discussed phenomena inspire us to explore other structured light fields for the expansion of applications in biomedical, information science, quantum optics, and so on.
