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 …

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 …

Metamaterials constructed from deep subwavelength building blocks have been used to
demonstrate phenomena ranging from negative refractive index and ε-near-zero to cloaking …

Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

In this work, it is experimentally demonstrated that the nonseparability of vector beams (eg,
radial and azimuthal polarization) can be used to encode information for optical …

A few years ago the possibility of coupling and inter-converting the spin and orbital angular
momentum (SAM and OAM) of paraxial light beams in inhomogeneous anisotropic media …

A tomographic measurement is a ubiquitous tool for estimating the properties of quantum
states, and its application is known as quantum state tomography (QST). The process …

Quantum approaches relying on entangled photons have been recently proposed to
increase the efficiency of optical measurements. We demonstrate here that, surprisingly, the …

Vector beams have the defining property of nonseparable spatial and polarization degrees
of freedom and are now routinely generated in the laboratory and used in a myriad of …

The statistical description of optical fields in classical coherence theory is the foundation for
many applications in metrology, microscopy, lithography and astronomy. Partial coherence …
