“…[19,20,36] As a result, quantum analogies are not limited to free-space light beams. For instance, the Schrödinger equation and related processing methods were also extended to study the classical light behavior in fibers, [46,47] nonlinear media, [48,49] and complex waveguide systems. [50,51] More typical examples and details will be reviewed in the following sections.…”

Controlling the various degrees‐of‐freedom (DoFs) of structured light at both quantum and classical levels is of paramount importance in optics. It is a conventional paradigm to treat diverse DoFs separately in light shaping. While, the more general case of nonseparable states of light, in which two or more DoFs are coupled in a nonseparable way, has become topical recently. Importantly, classical nonseparable states of light are mathematically analogue to quantum entangled states. Such similarity has hatched attractive studies in structured light, for example, the spin‐orbit coupling in vector beams. However, nonseparable classical states of light are still treated in a fragmented fashion, while its forms are not limited by vector beams and its potential is certainly not fully exploited. For instance, exotic space‐time coupled pulses open nontrivial light shaping toward ultrafast time scales, and ray‐wave geometric beams provide new dimensions in optical manipulations. Here, a bird's eye view on the rapidly growing but incoherent body of work on general nonseparable states involving various DoFs of light is provided and a unified framework for their classification and tailoring, providing a perspective on new opportunities for both fundamental science and applications, is introduced.

“…For example, the orbital angular momentum (OAM) of light, revealing the helical phase distribution in a vortex beam, is a combination of space and phase. − The OAM that has salient topological property with phase singularity and topological charge has opened novel chapters in singular optics, as well as advanced applications from communication to imaging. , Note that the OAM is not the only result of such DoF combination, which can be generalized into cases of vortex lattices or multisingularity arrays if we consider more complex spatial distribution. − As another example, the space–time nonseparability acts as a DoF unveiling general structures in optical pulses, breaking the limits of the traditional solution of the wave equation that the spatial and temporal variables are treated separately. , The space–time nonseparable wave packet also plays an important role in exploring anomalous and extreme physical effects . Additionally, the time and wavelength/frequency are combined in coherent chirped pulses, where the pulse temporal profile fulfills the Fourier relation with the spectrum, which lays the foundation of various pulse-shaping technologies. − Therefore, it is an effective strategy to extend new DoF of light and study new physical effects by combining the basic DoFs of light. For example, a more general vector vortex beam has spatially variant singular phase and polarization described by the total angular momentum, which allows the vector beam to have stronger tunability than the scalar vortex beam for reaching a wider range of applications. − How arbitrarily can light be shaped?…”

Structured light recently highlighted the higher-dimensional control with many tailored degrees of freedom (DoFs) such as amplitude, wavelength, polarization, and orbital angular momentum (OAM), spurring the extension of fundamental science and advanced applications, especially as the novel information carrier to meet the requirement of everlastingly increasing communication bandwidth and security. In addition to the basic DoFs in light, there are also several complex DoFs hidden in spin−orbital coupled vector beams, ray-wave geometric modes, spatiotemporal vortex rings, etc., extending the structured light manipulation. In this Review, we summarize a systematic technical roadmap on how to extend multiple DoFs step-by-step beyond the conventional OAM beams, creating new forms of ultra-DoF structured light, and present a tutorial on how to exploit multiple DoFs of light as advanced information carriers, especially with the recent assistance of artificial intelligence or deep learning method, enhancing the capacity, security, and dimension for the next-generation information technologies.

“…The topological properties of light have been a subject of fascination and intense research interest over the last half century [1][2][3] with implications for light-matter interactions [4][5][6], nonlinear physics [7][8][9], spin-orbit coupling [10][11][12], microscopy and imaging [13][14][15], metrology [16], and information transfer [17][18][19]. Light pulses can be simultaneously structured in space and time domains [20][21][22][23][24].…”

Supertoroidal light pulses, as space-time nonseparable electromagnetic waves, provided unique super-resolution topological properties including skyrmionic configurations, fractal-like singularities, and energy backflow in free space, which however do not survive upon propagation. Here we introduce the nondiffracting supertoroidal pulses (NDSTPs), propagation-robust skyrmionic and vortex-ring field that endure the singular configurations over arbitrary propagation distances. Intriguingly, the field structure of NDSTPs has a strong similarity with a von Kármán vortex street, a pattern of swirling vortices in fluid and gas dynamics, as the "singing" of suspended telephone lines in wind. NDSTPs allow the study of the propagation dynamics of electromagnetic skyrmionic fields and will be of interest as directed energy channels for information transfer applications.
