Hughes and his Air Force Office of Scientific Research-funded team have conducted high data-rate experiments using an optical laser link, a tool which exploits the quantum noise of light for higher security. The system uses adaptive optics for transmission of high data-rate video and audio signals over long distances.
AOptix Technologies, a developer of ultra-high bandwidth laser communication solutions for government and commercial markets has joined forces with AFOSR and AFRL to conduct flight tests at 10,000 feet to evaluate the performance of the high-altitude, air-to-ground, quantum communications links.
Up to this point, the challenge with free space optical links, which use fiber optics for transmission have been the turbulence or distortions from temperature differences that cause motion or wind in the atmosphere.
"When you transmit information through turbulence (motion in the atmosphere caused by turbulent cells or "wind") it's distorted just like the information coming from the light reflected off a distant, twinkling star to your eye. It's fuzzy," said Hughes. "You have to overcome that by using adaptive optics to rectify the distortion and get a better quality signal."
As of right now, Hughes and his team have established an optical link without distortion in test situations at a distance of 35 kilometers in both stationary and flight situations. The next flight test will aim for increased altitudes to demonstrate further air-to-ground distances.
"If we can now put one link on the ground and one on a demo aircraft, it wouldn't take much to apply the technology to operational aircraft for the Air Force," said Hughes.
"This new capability may even save lives because it will enable the military to access ultra-high bandwidth ISR (intelligence, surveillance reconnaissance) information in real-time from various manned and unmanned airborne platforms," said Dean Senner, President & CEO of AOptix Technologies.ABOUT AFOSR:

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
