Many polarisation techniques have been harnessed for decades in biological and clinical
research, each based upon measurement of the vectorial properties of light or the vectorial …

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 …

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 …

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 …

Quantum networks provide the framework for quantum communication, clock
synchronization, distributed quantum computing, and sensing. Implementing large-scale …

The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven
by the tremendous developments in the toolkit for the creation, control and detection of what …

The pace of innovations in the field of optical trapping has ramped up in the past couple of
years. The implementation of structured light, leading to groundbreaking inventions such as …

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 …

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 …
