In February 2023, Wits researchers announced a new approach to studying complex light in complex systems, such as transporting classical and quantum light through optical fibre, underwater channels, ...

Researchers from Wits University and Universitat Autònoma de Barcelona show how controlling the structure of photons in space and time enables tailored quantum states for next-generation communication ...

Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two ...

Everyday experience tells us that light reflected from a perfectly flat mirror will give us the correct image without any deformation. Interestingly, this is not the case when the light field itself ...

Light doesn’t just travel in straight lines—it can also twist. And when it does, it opens new frontiers in science and medicine. A recent breakthrough led by Professor Igor Meglinski at Aston ...

Photonics researchers have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's ...

This Collection supports and amplifies research related to SDG 9 - Industry, Innovation and Infrastructure. The ability to control the phase, polarization, and intensity of light is extensively ...

Scientists at the University of East Anglia have uncovered a hidden property of light that allows it to twist, spin and behave differently—without mirrors, materials or special lenses. In a ...
