Graphene device makes ultrafast light to energy conversion possible

By - April 15, 2015 1 Picture
Converting light to electricity is one of the pillars of modern electronics, with the process essential for the operation of everything from solar cells and TV remote control receivers through to laser communications and astronomical telescopes. These devices rely on the swift and effective operation of this technology, especially in scientific equipment, to ensure the most efficient conversion rates possible. In this vein, researchers from the Institute of Photonic Sciences (Institut de Ciències Fotòniques/ICFO) in Barcelona have demonstrated a graphene-based photodetector they claim converts light into electricity in less than 50 quadrillionths of a second.

New chip could turn phone cameras into high-res 3D scanners

By - April 7, 2015 2 Pictures
As if smartphones can't already do enough, soon they may be able to scan three-dimensional objects and send the resultant high-resolution 3D images to a 3D printer that produces hyper-accurate replicas. This comes thanks to a small and inexpensive device called a nanophotonic coherent imager (NCI), which was developed by scientists at Caltech. The NCI could add 3D imaging to a variety of other devices and applications such as improving motion sensitivity in human machine interfaces and driverless cars. Read More
