SEM images of a 'lossless' metamaterial that behaves simultaneously as a metal and a semiconductor. Credit: Ultrafast and Nanoscale Optics Group at UC San Diego 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 light-based technologies including fiber optic communication systems, lasers and photovoltaics.
