Infrared amplifier reaches the nanoscale

Researchers in China and the US have unveiled the first nanoscale amplifier for light at the technologically important telecommunications wavelength of 1.55 µm (or the near-infrared). The new device, which is 20 times more powerful than previous such amplifiers that measured microns across, is small enough to fit on an integrated circuit. This means that it could help make for the next generation of faster, more efficient, nanophotonics components.
