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 …

Since their first introduction in 2006, q-plates have found a constantly increasing number of
uses in diverse contexts, ranging from fundamental research on complex structured light …

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 concept of entanglement is so synonymous with quantum mechanics that the prefix
“quantum” is often deemed unnecessary; there is after all only quantum entanglement. But …

Indirect-imaging methods involve at least two steps, namely optical recording and
computational reconstruction. The optical-recording process uses an optical modulator that …

The concept of skyrmions, which refers to topologically stable vector textures and was
originally introduced in particle physics, has recently been transferred to various types of …

The rapid developments in orbital-angular-momentum-carrying Laguerre-Gaussian (LG l 0)
modes in recent years have facilitated progress in optical communication …

Orbital angular momentum (OAM) beams with topological charge ℓ are commonly generated
and detected by modulating an incoming field with an azimuthal phase profile of the form …

Light beams carrying orbital-angular-momentum (OAM) play an important role in optical
manipulation and communication owing to their unbounded state space. However, it is still …

We show that a product of two Laguerre–Gaussian (pLG) beams can be expressed as a
finite superposition of conventional LG beams with particular coefficients. Based on such an …
