    Editorial: Singular and Correlation Optics
    (2021) Angelsky, Oleg V.; Bekshaiev, Oleksandr Yа.; Hanson, Steen G.; Mokhun, Igor I.; Vasnetsov, Mikhail V.; Wang, Wei; Бекшаєв, Олександр Янович; Бекшаев, Александр Янович
    Singularities in wave fields form a relatively young concept of wave physics originating from the seminal article by Nye and Berry. Initially, this concept seemed rather abstract and curious, but the development of laser optics has demonstrated the ubiquity of optical singularities and their exceptional power in characterization, control, and applications of light fields. The era of singular optics started, and now, it is difficult to indicate another area of optics that is developing so rapidly and steadily.

    Singularities in wave fields form a relatively young concept of wave physics originating from the seminal article by Nye and Berry [1]. Initially, this concept seemed rather abstract and curious, but the development of laser optics has demonstrated the ubiquity of optical singularities and their exceptional power in characterization, control, and applications of light fields. The era of singular optics started [2, 3], and now, it is difficult to indicate another area of optics that is developing so rapidly and steadily.

    Structured Light: Ideas and Concepts
    (2020) Angelsky, Oleg V.; Bekshaiev, Oleksandr Yа.; Hanson, Steen G.; Zenkova, Claudia Yu.; Mokhun, Igor I.; Jun, Zheng
    The paper briefly presents some essential concepts and features of light fields with strong spatial inhomogeneity of amplitude, phase, polarization, and other parameters. It contains a characterization of optical vortices, speckle fields, polarization singularities. A special attention is paid to the field dynamical characteristics (energy, momentum, angular momentum, and their derivatives), which are considered not only as mechanical attributes of the field but also as its meaningful and application-oriented descriptive parameters. Peculiar features of the light dynamical characteristics in inhomogeneous and dispersive media are discussed. The dynamical properties of paraxial beams and evanescent waves (including surface plasmon–polaritons) are analyzed in more detail; in particular, a general treatment of the extraordinary spin and momentum, orthogonal to the main propagation direction, is outlined. Applications of structured light fields for optical manipulation, metrology, probing, and data processing are described.
