JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]A laser-based space communication system developed by researchers at Chalmers University of Technology uses an almost noiseless preamplifier to improve reach and data rates for space communications. The research has implications for technologies such as intersatellite communication, deep-space missions, and Earth monitoring with lidar. The Chalmers team’s system overcomes losses over large distances in space by significantly increasing the sensitivity of the receiver, while encoding information onto a single wave, which, along with a pump wave at a different frequency, generates a...Read full articleRelated content from Photonics MediaArticlesSignal Processing Algorithms Cut Turbulence in Free-Space CommunicationsResearchers from Aston University and Glasgow University have created signal-processing algorithms to help mitigate the impact of turbulence in free-space optical experiments.
