Researchers at the University of the Witwatersrand (Wits) have outlined a new optical communication protocol that exploits spatial patterns of light for multi-dimensional encoding in a manner that does not require the patterns to be recognised, thus overcoming the prior limitation of modal distortion in noisy channels.
Rutgers is part of a new federally funded regional collaboration to drive economic and technological advancements in photonics, the National Science Foundation (NSF) announced. The consortium, which includes researchers from Rutgers-Newark and Rutgers-New Brunswick, awarded a development grant from the NSF’s Regional Innovation Economic Engine consortium, led by Princeton University and co-led by Rowan University, with partners throughout New Jersey and neighboring states Delaware, Pennsylvania and New York.
Fibre-optic cables line the coasts of the continents and criss-cross the oceans, carrying signals that are the backbone of communication in the modern world.
In the issue of the renowned journal Science published today (10.3.23), the team led by Prof. Dr Ulf Peschel reports on measurements on a sequence of pulses that travel thousands of kilometres through glass fibres that are only a few microns thin.
The more-than 1.2 million km of fibre-optic cables that criss-cross the planet carry the world’s phone calls, internet signals and data.
Optical fibres are the backbone of our modern information networks. From long-range communication over the internet to high-speed information transfer within data centres and stock exchanges, optical fibre remains critical in our globalised world.
In a paper published today in Science Advances, researchers at the University of Oxford have developed a method using the polarisation of light to maximise information storage density and computing performance using nanowires.
Researchers are developing the nation’s first drone-based, mobile quantum network for unhackable wireless communication. The network includes drones, a ground station, lasers and fiber optics. In war, these drones would provide one-time crypto-keys to exchange critical information, which spies and enemies would not be able to intercept. Quantum protects information using the laws of nature and not just by a clever manmade code.
Oxford University researchers have developed a sensor made of sapphire fibre that can tolerate extreme temperatures, with the potential to enable significant improvements in efficiency and emission reduction in aerospace and power generation.
