We live in an age of long-range information. Research is turning towards the use of lasers which have several advantages. However, this new technology faces a major problem: clouds. Due to their density, clouds stop the laser beams and scramble the transfer of information. Researchers at UNIGE have devised an ultra-hot laser that creates a temporary hole in the cloud, which lets the laser beam containing the information pass through.

Researchers at the universities in Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future rapid optical communication", says Feng Gao, researcher at Linköping University.

Scientists have assumed that future terahertz data links would have an inherent immunity to eavesdropping, but new research shows that's not necessarily the case.

Graphene Flagship industrial and academic partners published a new paper in Nature Reviews Materials analysing the possibilities of graphene in the internet of everything market, expected to reach over 12 billion connected devices in 2020

A new study from the NYU College of Global Public Health and NYU Tandon School of Engineering, published in Nature Digital Medicine, used text message surveys to determine in real time how people used maternal health services during a recent Ebola outbreak and measured a drop in hospital-based births during the outbreak.

An international team of scientists led by the University of Groningen's Zernike Institute for Advanced Materials has identified a way to create quantum bits that emit photons that describe their state at wavelengths close to those used by telecom providers. These qubits are based on silicon carbide in which molybdenum impurities create color centers. The results were published in the journal npj Quantum Information on Oct. 1.

Researchers at EPFL have found a way to implement an optical sensing system by using spatial multiplexing, a technique originally developed in optical-fiber communication. The method, which produces three independent streams of ultrashort optical pulses using a single continuous-wave laser and a single optical microresonator, is far simpler than existing technologies.

A research team comprising members from City University of Hong Kong (CityU), Harvard University and renowned information technologies laboratory has successfully fabricated a tiny on-chip lithium niobate modulator, an essential component for the optoelectronic industry. The modulator is smaller, more efficient with faster data transmission and costs less than traditional ones. The technology is set to revolutionise the industry.
