Researchers at Leti recently created a photonic coupler with one waveguide made from III–V materials and another from silicon. The achievement marks an advance toward fast, accurate, low-cost multigas sensors. A complete gas testing system including waveguides would be capable of taking measurements at the liter scale, rather than at the cubic meter scale required […] >>

Thin films formed by sol-gel synthesis are not, in fact, homogeneous! Researchers at Liten’s INAC made the discovery observing an InGaZnO thin film at the ESRF, where x-ray microscopy and grazing-incidence small-angle scattering revealed the formation of mesopores and self-assembled nanometric aggregates rich in zinc and gallium. Indium oxide played the role of matrix. Now […] >>

Photonics-on-silicon components could dramatically reduce the form factor of the data switches used in telecommunications switching centers. Leti and the other partners in the Celtic-Plus SASER (Safe and Secure European Routing) project, which will run until the end of 2015, are looking at how. The project consortium presented a demonstrator made up of two 16-wavelength […] >>

Could magnetocardiography (MCG) and magnetoencephalography (MEG) one day be available to the masses? Clinatec is currently running a clinical trial to find the answer. The trial, named Minimag, will test the signal-recording capacities of an optically-pumped helium-4 magnetometer, originally designed for the Swarm space mission, on sixteen volunteer subjects. MCG and MEG would be extremely […] >>

Flip-flops are data storage elements used in integrated circuits. And while flip-flops are good, non-volatile flip-flops are even better! The latest generation of magnetic tunnel junctions (MTJs), known as spin-orbit torque (SOT) MTJs, could be the key, delivering crucial speed, energy efficiency, and robustness. Researchers at Spintec created a model of the SOT-MTJs for the […] >>
