Researchers from Duke University demonstrate a new optical waveguide capable of bending photons around tight corners on a smaller scale than previously possible. The technology is made possible by through photonic crystals using the concept of topological insulators.
Steerable electro-evanescent optical refractor (SEEOR) chips take laser light in the mid-wavelength infrared (MWIR) as an input and steers the beam at the output in two dimensions without the need for mechanical devices.
New survey: Health system leaders plan to increase spending to defend against cyberattacks, express optimism about reimbursement for telehealth services, and feel anxiety about Apple, Amazon and Google entering the health care space.
Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This discovery could enable future developments in LED lighting, quantum sensing, quantum communication and future quantum computing. The study has just been published in the renowned journal Nature.
Researchers at the University of Waterloo have taken a huge step towards making smart devices that do not use batteries or require charging.
Web browsers use GPUs to render graphics on desktops, laptops, and smart phones. GPUs are also used to accelerate applications on the cloud and data centers. GPUs are usually programmed using application programming interfaces, or APIs, such as OpenGL. OpenGL is accessible by any application on a desktop with user-level privileges. Since desktop or laptop machines by default come with the graphics libraries and drivers installed, the attack can be implemented easily using graphics APIs.
Researchers Lingjia Liu and Yang (Cindy) Yi are using brain-inspired machine learning techniques to increase the energy efficiency of wireless receivers.
University of Adelaide researchers have delved into the realm of Star Wars and created a powerful tractor beam -- or light-driven energy trap -- for atoms.
A joint study by the BBC, UCL and the University of Barcelona shows that in virtual reality news experiences, basic interactivity can increase buy-in without compromising faithful reporting.
This world-first nanophotonic device, unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' light.
