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 ...

Fiber optics has been the center of all modern telecommunications with its capacity for high-speed, long-distance internet that many enjoy today. However, the continuing demand for internet traffic ...

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 ...

Laser Communications could reshape military space networks as research shows adaptable laser links nearing use.

Electrical engineers at the University of California, San Diego developed a receiver that can detect a weak, fast, randomly occurring signal. The study, published in the Dec. 11 issue of Science, lays ...

On the left is a conceptual schematic of a future THz communication system, featuring an astronomical telescope situated on the Qinghai-Tibet Plateau serving as the receiver for satellite and airborne ...

One important outcome of this work is that it could, in principle, be applied to M -ary-state phase-shift keying, which suggests that employing a quantum receiver in a multilevel modulation optical ...
