Making 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 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 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 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 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 ArticleNASA laser communications to provide Orion faster connections
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 ArticleSimultaneously simulating electrical and optical input achieves unprecedented...
A key interface component between electronic and light-based circuits receives a boost in performance through A*STAR research that combines previously independent simulations of the two systems. This...
View ArticleOptical communication at record-high speed via soliton frequency combs...
Optical solitons are special wave packages that propagate without changing their shape. In optical communications, solitons can be used for generating frequency combs with various spectral lines, which...
View ArticleAtomic cousins team up in early quantum networking node
Large-scale quantum computers, which are an active pursuit of many university labs and tech giants, remain years away. But that hasn't stopped some scientists from thinking ahead, to a time when...
View ArticleNew technique to suppress sound waves from disorder to improve optical fiber...
Energy loss due to scattering from material defects is known to set limits on the performance of nearly all technologies that we employ for communications, timing, and navigation. In micro-mechanical...
View ArticleLight to break bandwidth ceiling
The rise of big data and advances in information technology has serious implications for our ability to deliver sufficient bandwidth to meet the growing demand.
View ArticleLens trick doubles odds for quantum interaction
It's not easy to bounce a single particle of light off a single atom that is less than a billionth of a metre wide. However, researchers at the Centre for Quantum Technologies at the National...
View ArticleSecure information transmission over 500m fiber links based on quantum...
Quantum secret communication realizes secure information transmission-based on quantum principles. At present, the most developed quantum secret communication schemes are-based on quantum key...
View ArticleHigh-speed communication systems based on ultraviolet radiation
Military and civil authorities could benefit from secure optical communication systems that use light to carry messages between moving vehicles. Researchers at KAUST have now demonstrated rapid data...
