Silicon and laser: a brilliant pairing!

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, […]

From springs to lasers: energy’s mysterious cycle

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 […]

Medicine for Materials

Did you know that materials have health problems too? To diagnose their structural integrity, researchers are increasingly using techniques similar to those used in the medical field for humans. X-rays, temperature checks and ultrasound imaging are just a few of the tools that help detection of abnormalities in parts. The advantage of these various techniques […]

What is photomechanics?

How can we measure the deformation of a stratospheric balloon composed only of an envelope a few micrometers thick? It is impossible to attach a sensor to it because this would distort the envelope’s behavior… Photomechanics, which refers to measurement methods using images and computer analysis, makes it possible to measure this deformation or a […]
