A novel technique developed by MIT researchers rethinks hardware data compression to free up more memory used by computers and mobile devices, allowing them to run faster and perform more tasks simultaneously.
Engineers at the University of California, Berkeley have built a new photonic switch that can control the direction of light passing through optical fibers faster and more efficiently than ever. This optical 'traffic cop' could one day revolutionize how information travels through data centers and high-performance supercomputers that are used for artificial intelligence and other data-intensive applications.
The National Institute of Information and Communications Technology and Furukawa Electric Co., Ltd. report a record SDM transmission experiment using multi-core fiber amplifier. Fully decoded optical data transmission of 715 Tb/s was achieved over a distance of 2,009 km in 19-core cladding pumped erbium doped fiber amplifier (EDFA) amplified MCF link using coded polarization division multiplexed (PDM) --16 quadrature-amplitude modulation (QAM) of 345 carriers over the C and L band in a re-circulating transmission loop.
A team of engineers has developed a series of 3D printed metamaterials with unique microwave or optical properties that go beyond what is possible using conventional optical or electronic materials. The fabrication methods developed by the researchers demonstrate the potential, both present and future, of 3D printing to expand the range of geometric designs and material composites that lead to devices with novel optical properties.
Researchers from the NUS-Singtel Cyber Security Research & Development Laboratory demonstrate a way to improve quantum key distribution over fiber networks.
University of Central Florida researchers have developed a way to control the speed of light. Not only can they speed up a pulse of light and slow it down, they can also make it travel backward.
At the University of Missouri, researchers in the College of Engineering are applying one of the first uses of deep learning -- the technology computers use to intelligently perform tasks such as recognizing language and driving autonomous vehicles -- to the field of materials science.
Engineering researchers have demonstrated that a longstanding theoretical method called direct antenna modulation has real-world utility for boosting the quality of radio signals when transmitting at high data rates. The finding has applications in fields such as military communications.
Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6%, which is a record. The results have been published in Nature Photonics.
The motto 'united we stand, divided we fall' has found new application in cyber security. Machines must transmit information in order to process it. A self-driving car, for instance, is designed to collect information and respond in kind. But what if there's another, adversarial signal in the mix, jeopardizing the communication? A research team at University of Illinois at Urbana-Champaign developed a method to potentially avoid the interruptions caused by these signals, called jammers.
