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 …

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 …

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 …

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

Structured light is derived from the ability to tailor light, usually referring to the spatial control
of its amplitude, phase, and polarization. Although a venerable topic that dates back to the …

Vector beams, and in particular vector vortex beams, have found many applications in recent
times, both as classical fields and as quantum states. While much attention has focused on …

Vector vortex beams are conventionally created as the superposition of orbital angular
momentum (OAM) modes with orthogonal polarizations, limiting the available degrees of …

We propose theoretically and verify experimentally a method of combining a q-plate and a
spiral phase plate to generate arbitrary vector vortex beams on a hybrid-order Poincaré …

Superposition of orbital angular momentum (OAM) states has attracted considerable
attention due to its application in diverse scientific areas, such as high-capacity optical …

Vector beams, non-separable in spatial mode and polarisation, have emerged as enabling
tools in many diverse applications, from communication to imaging. This applicability has …
