Many polarisation techniques have been harnessed for decades in biological and clinical
research, each based upon measurement of the vectorial properties of light or the vectorial …

Optical trap** describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trap** with a single beam, this is …

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 …

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

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 …

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

Quantum metrology is one of the most promising applications of quantum technologies. The
aim of this research field is the estimation of unknown parameters exploiting quantum …

Optical vector vortex beams provide additional degrees of freedom for spatially
distinguishable channels in data transmission. Although several coherent light sources …

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 …

In recent times, the optical-analogous skyrmions, topological quasiparticles with
sophisticated vectorial structures in light, have received an increasing amount of interest …
