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 …

Thirty years ago, Coullet et al. proposed that a special optical field exists in laser cavities
bearing some analogy with the superfluid vortex. Since then, optical vortices have been …

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 …

The term Poincaré beam, which describes the space-variant polarization of a light beam
carrying spin angular momentum (SAM) and orbital angular momentum (OAM), plays an …

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

Optical elements that convert the spin angular momentum (SAM) of light into vortex beams
have found applications in classical and quantum optics. These elements—SAM-to–orbital …

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 …

Optical tweezers employing forces produced by light underpin important manipulation tools
employed in numerous areas of applied and biological physics. Conventional optical …

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 …

Vector vortex beams (VVBs) possess ubiquitous applications from particle trapping to
quantum information. Recently, the bulky optical devices for generating VVBs have been …
