All light has structure, but only recently has it been possible to control it in all its degrees of
freedom and dimensions, fuelling fundamental advances and applications alike. Here we …

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 …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Optical aberrations place fundamental limits on the achievable resolution with focusing and
imaging. In the context of structured light, optical imperfections and misalignments and …

Structured light recently highlighted the higher-dimensional control with many tailored
degrees of freedom (DoFs) such as amplitude, wavelength, polarization, and orbital angular …

The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven
by the tremendous developments in the toolkit for the creation, control and detection of what …

Geometric arrays of vortices found in various systems owe their regular structure to mutual
interactions within a confined system. In optics, such vortex crystals may form spontaneously …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …

Orbital angular momentum (OAM) from lasers holds promise for compact, at-source
solutions for applications ranging from imaging to communications. However, conjugate …

Abstract Information encryption with optical technologies has become increasingly important
due to remarkable multidimensional capabilities of light fields. However, the optical …
