Engineering Light for a Wireless World
At the Wits Optical Communication Lab, we engineer light to create the next generation of wireless communication—delivering fibre-optic performance, without the physical fibre. We achieve this by structuring laser beams (optical modes) and developing novel information-theoretic frameworks to push the boundaries of what is possible.
Our work is primarily experimental, complemented by rigorous theory and simulation, and focuses on three core thrusts:
- Long-Range Free-Space Optics (FSO): Exploring the ultimate limits of distance and data rate for laser communication through the atmosphere, using techniques like mode-division multiplexing to enhance capacity and resilience.
- Visible Light Communication (VLC): Transforming ubiquitous indoor and outdoor lighting into secure, high-speed wireless networks for a connected future.
- All-Optical AI: Repurposing the physics of light propagation through complex media as a new form of analogue computation, turning the channel itself into the computer.
Our research is driven by a team of creative and self-motivated postgraduate students. If you are interested in solving fundamental problems and building the future of communication, learn more about joining us.
