Structured Light Revolution: Noise-Free Optical Communication Demonstrated — A new approach to optical |
New research in structured light means researchers can exploit the many patterns of light as an encoding alphabet without worrying about how noisy the channel is. Credit: Wits UniversityThe patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence or in bent optical fiber.
“This is a very exciting advance because we can finally exploit the many patterns of light as an encoding alphabet without worrying about how noisy the channel is,” says Professor Andrew Forbes, from the Wits School of Physics. “In fact, the only limit to how big the alphabet can be is how good the detectors are and not at all influenced by the noise of the channel.”

Breakingviews - Lessons from the original Industrial RevolutionThere is much excited chatter that automation will unleash a Fourth Industrial Revolution, building on earlier upheavals caused by the arrival of steam power, electricity, and semiconductors. Yet in Britain, which gave birth to the first of those transformations, economic growth has stalled. If policymakers wish to escape the low-productivity trap, they should study the conditions that sparked the first period of sustained economic growth some three hundred years ago. These are brilliantly described by Martin Hutchinson, a former Breakingviews columnist, in his new book “Forging Modernity: Why and How Britain Developed the Industrial Revolution”.
