GOTHENBURG, Sweden (Charlmers University of Technology) — Communications in space demand the most sensitive receivers possible for maximum reach, while also requiring high bit-rate operations. A novel concept for laser-beam based communications, using an almost noiseless optical preamplifier in the receiver, was recently demonstrated by researchers at Chalmers University of Technology, Sweden.
