'Lossless' metamaterial could boost efficiency of lasers and other light-based devices
Lossless metamaterial lasers other light-based devices
2017/3/14
Engineers at the University of California San Diego have developed a material that could reduce signal losses in photonic devices. The advance has the potential to boost the efficiency of various ligh...
Lasers have become indispensable to modern life since they were invented more than fifty years ago. The ability to generate and amplify light waves into a coherent, monochromatic and well-focused beam...
A technique for regulating the tempo of heartbeats with short flashes of light could lead to a less intrusive type of pacemaker, say researchers in the US. A team led by Andrew Rollins at Case Western...
