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, ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2024.230052 discusses structured light beams with controllable polarization along arbitrary trajectories. A structured light refers to ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...

In a lab at Osaka University, physicist Yoshiki Nakata and his colleagues fired a pulsed laser through a stack of three passive optical components and watched it shatter into 3,070 tiny, spinning ...
