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 …

A few decades ago, quantum optics stood out as a new domain of physics by exhibiting
states of light with no classical equivalent. The first investigations concerned single photons …

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 has become topical of late, where controlling light in all its degrees of
freedom has offered novel states of light long predicted, enhanced functionality in …

A quantitative analysis of optical fields is essential, particularly when the light is structured in
some desired manner, or when there is perhaps an undesired structure that must be …

The resolution of optical imaging devices is ultimately limited by the diffraction of light. To
circumvent this limit, modern superresolution microscopy techniques employ active …

Improving axial resolution is crucial for three-dimensional optical imaging systems. Here we
present a scheme of axial superresolution for two incoherent point sources based on spatial …

It is well known in Bayesian estimation theory that the conditional estimator attains the
minimum mean squared error (MMSE) for estimating a scalar parameter of interest. In …

We found that small perturbations of the optical vortex core in Laguerre–Gaussian (LG)
beams generate a fine structure of the Hermite–Gaussian (HG) mode spectrum in the form of …

Orbital angular momentum (OAM) of an optical vortex has attracted great interest from the
scientific community due to its significant values in high-capacity optical communications …
