Researchers at Télécom ParisTech, in partnership with the University of California, Santa Barbara (UCSB), have developed new optical sources. These thermally-stable, energy-saving lasers offer promising potential for silicon photonics. These new developments offer numerous opportunities for improving very high-speed transmission systems, like datacomms and supercomputers. Their results were published in Applied Physics Letters last summer, […]
In 1953, scientists theorized the energy behavior of a chain of springs and revealed a paradox in fundamental physics. Over 60 years later, a group of researchers from IMT Lille Douai, CNRS and the universities of Lille and Ferrara (Italy) has succeeded in observing this paradox. Their results have greatly enhanced our understanding of physical […]
FEMTO-Engineering, part of Carnot Télécom & Société numérique institute, offers manufacturers a new cutting and drilling technique for transparent materials. By using a femtosecond laser, experts can reach unrivalled levels of precision when manufacturing ultra-hard materials. Jean-Pierre Goedgebuer, director of FC’Innov (FEMTO-Engineering), explains how the technique works. What is high aspect ratio precision machining and […]
3D printing is a manufacturing process used for both consumer and industrial applications in the aeronautics, automotive, rail and medical industries. The Shoryuken project being developed at IMT Nord Europe aims to improve the mechanical performance of the objects printed using plastic and composite materials. To accomplish this, it combines 3D printing with laser welding […]
What if barcodes disappeared from our supermarket items? Étienne Perret, a researcher in radio-frequency electronics at Grenoble INP, works on identification technologies. His work over recent years has focused on the development of RFID without electronic components, commonly known as chipless RFID. The technology aims to offer some of the advantages of classical RFID but […]
Xavier Lagrange, Professor of network systems, IMT Atlantique – Institut Mines-Télécom [divider style=”normal” top=”20″ bottom=”20″] 5G is the fifth generation of standards for mobile networks. Although this technology has fueled many societal debates on its environmental impact, possible health effects, and usefulness, here we will focus on the technological aspects. How does 5G work? Is […]
We know how to use wind to produce electricity, but large three-bladed turbines do not have their place in urban environments. The start-up Unéole has therefore developed a wind turbine that is suitable for cities, as well as other environments. It also offers a customized assessment of the most efficient energy mix. Clovis Marchetti, a […]
Measuring and quantifying have informed Véronique Bellon-Maurel’s entire scientific career. A pioneer in near infrared spectroscopy, the researcher’s work has ranged from analyzing fruit to digital agriculture. Over the course of her fundamental research, Véronique Bellon-Maurel has contributed to the optimization of many industrial processes. She is now the Director of #DigitAg, a multi-partner Convergence […]
Rogue waves are powerful waves that erupt suddenly. They are rare, but destructive. Above all, they are unpredictable. Surprisingly, researchers have been able to better understand these fascinating waves by studying similar phenomena in fiber optic lasers. Before scientists began measuring and observing them, rogue waves had long been perceived as legends. They can […]
Two teams from IMT Atlantique and Mines Saint-Étienne have developed an autonomous contact lens which is powered by an integrated flexible micro-battery. This invention is a world first that opens new health prospects, whilst also opening the door for scientists to develop other human-machine interfaces. Human augmentation, a field of research that aims to […]
