A team from the US Department of Energy's Lawrence Berkeley National
Laboratory (Berkeley Lab) has created a 2D laser just one molecule thick that promises to make significant
advances in ultra-compact photonic components for the likes of quantum
computers and the next generation of optoelectronic devices.
Using nanometer-size metamaterials, researchers at Missouri University of Science and Technology have developed a technique to print images that uses the manipulation of light, rather than the application of ink, to produce colors. This "no-ink" printing method has been demonstrated by producing a Missouri S&T athletic logo just 50 micrometers wide.
