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 …

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

Free-space optical communication is a promising means to establish versatile, secure and
high-bandwidth communication between mobile nodes for many critical applications. While …

Structured light is routinely used in free-space optical communication channels, both

With the ever-increasing demand for data and the radio frequency spectrum becoming
congested, free space optics (FSO) may find a niche for situations where fiber is too …

Vector vortex beams are structured states of light that are nonseparable in their polarisation
and spatial mode, they are eigenmodes of free-space and many fiber systems, and have the …

Quantum mechanics is now a mature topic dating back more than a century. During its
scientific development, it fostered many technological advances that now are integrated into …

Optical communication is an integral part of the modern economy, having all but replaced
electronic communication systems. Future growth in bandwidth appears to be on the horizon …

Complex vector light fields, classically entangled in polarization and phase, have become
ubiquitous in a wide variety of research fields. This has triggered the demonstration of a …
