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 ...
image: Researchers in Sweden recently demonstrated a novel concept for laser-beam-based communication links using a near 'noiseless' optical pre-amplifier in the receiver. They demonstrated an ...
In space exploration, long-distance optical links can now be used to transmit images, films and data from space probes to Earth using light. But in order for the signals to reach all the way and not ...
