Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat at room temperature.
Light not only plays a key role as an information carrier for optical computer chips, but also in particular for the next generation of quantum computers.
Researchers at Princeton University and the University of Washington have developed a full-color nano-camera the size of a grain of salt. 1.6 million cylindrical nano-posts were etched on a silicon nitride layer. A neural image reconstruction algorithm manipulates the morphology of these nano-posts to create wide field-of-view (FOV) full-color images.

The research team led by Prof. PENG Xinhua from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, and the collaborators, achieved for the first time the experimental quantum superradiant phase transition (SPT) beyond no-go theorem by introducing anti-squeezing.
An international business–academia collaboration has yielded a new type of projector that can project RGB and invisible infrared images simultaneously and independently at a high speed of almost 1,000 fps.
Skoltech researchers and their colleagues have come one step closer to a working optoacoustic endoscopic probe — a device that could slip inside a blood vessel and analyze atherosclerotic plaques by shining laser light on them to make them wobble like a loudspeaker membrane and betray their chemical composition with an ultrasound signature.
Biomedical engineers at Duke University have engineered a holographic system capable of imaging and analyzing tens of thousands of cells per minute to both discover and recognize signs of disease.
Lasers in conventional laser printers for paper printouts are very small. 3D laser printers for 3-dimensional microstructures and nanostructures, by contrast, have required big and expensive laser systems so far.
The decommissioning of nuclear facilities poses major challenges for operators. Whether decommissioning or safe containment, the amount of nuclear waste to be disposed of is growing at an overwhelming rate worldwide.

Luminescent thermometers become progressively essential for remote, non-invasive temperature sensing at particularly small lateral dimensions, as contact-based detection methods only function in a partial way or even not at all. Standard application areas are temperature recording on catalytic surfaces or in biomedical procedures.
Jiming Bao, professor of electrical and computer engineering at the University of Houston, has developed a new fluid that can be cut open by light and demonstrated macroscopic depression of ferrofluid, the kind of fluid that can be moved around with a magnet.
Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view.
Glow-in-the-dark materials are utilized worldwide for emergency signs, watches, and paint. This useful characteristic fuels a global market worth approximately US$400 million.
The German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) today announced a further renewal of the Collaborative Research Center (CRC)/Transregio 142, "Tailor-made nonlinear photonics: From fundamental concepts to functional structures" at Paderborn University.
A small guest molecule in the right place makes it possible to produce energy-efficient organic solar cells using eco-friendly solvents. A record efficiency over 17% is demonstrated. In addition, solar cells with larger areas can be produced.
