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, ...

In free-space optical communication scenarios, atmospheric turbulence distorts the complex wavefront of signal-carrying light beams, leading to bit errors and even communication interruptions. Note ...

Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of ...

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 ...

Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de Barcelona, have demonstrated how quantum light can be engineered in space and ...
