Building off a breakthrough “anti-laser,” an international team of researchers (France, USA – Yale University) has developed a system that can direct light and other electromagnetic waves for signal processing without any unwanted signal reflections. Instead of transducing it into another form of energy, the device redirected to specific channels. It could either all go into chosen output channels or some of it could be absorbed and the rest go into the output channels. In the next step, they want to make a similar device where the absorption is negligible, so that all the energy is efficiently routed to perform its information or sensing function. The device eliminated signal reflections, which have long been a problem for signal routers. The innovation could advance local area networks, field of photonics, and other applications…read more.
