NASA is working to forever change the way astronauts communicate to and from space using an advanced laser communications system called LEMNOS, which will enable exponentially faster connections than...
View ArticlePlasmonic device offers broadband modulation to optical links at 100Gbit/s
Today's society is growing in population and productivity puts ever higher demands on the Internet, and without scientific developments to provide ways meeting our traffic needs, it will begin to clog....
View ArticleResearchers use holography to improve nanophotonic circuits
Nanophotonic circuits, tiny chips which filter and steer light, suffer from small random variations which degrade the transmission of light. Researchers have now found a way to compensate those...
View ArticleResearch opens door to smaller, cheaper, more agile communications tech
Research led by ANU on the use of magnets to steer light has opened the door to new communications systems which could be smaller, cheaper and more agile than fibre optics.
View ArticleResearchers break data transfer efficiency record
Researchers at the Department of Energy's Oak Ridge National Laboratory have set a new record in the transfer of information via superdense coding, a process by which the properties of particles like...
View ArticleMaking the switch to polarization diversity
Vast amounts of data transmit across the Internet and telecommunications networks delivering, for example, real-time video calls from one cell phone to another - across the world. As people send and...
View ArticleHighest core density realized with 12-core single-mode optical fiber
Enterprise networks and data centers continue to increase their demands for connectivity, with ever larger quantities of data expected to be transmitted in the foreseeable future. Over the past 20...
View ArticleScientists develop new metasurfaces for deep UV-imaging
Russian researchers have developed a new material that converts infrared light to ultrashort pulses of ultraviolet. For this purpose, the scientists exposed silicon film to a laser so that its relief...
