- "Replicator" 3d printer now easier to use and more accurate. Researchers use detailed optical simulations to simplify ultra-fast tomographic 3d printing down to only 2 parts: projector and rotating stage. These printers approach document printer speed, but for 3D objects. https://www.osapublishing.org/oe/fulltext.cfm?uri=oe-29-7-11037&id=449502 4 comments science
- A remote-sensing device can transform a trickle of incoming photons into a high-fidelity image of an object more than 200 kilometres away. Researchers built a type of single-photon lidar device that sends and receives one photon at a time. https://www.osapublishing.org/optica/fulltext.cfm?uri=optica-8-3-344&id=449006 5 comments science
- Scientists Use AI to create dielectric metamaterials that absorb & emit specific frequencies of terahertz radiation. It changed what could have been more than 2000 years of calculation into 23 hours, paving the way for the design of sustainable types of thermal energy harvesters & lighting. https://www.osapublishing.org/oe/abstract.cfm?uri=oe-27-20-27523 11 comments science
- A trio of physicists from the National Autonomous University of Mexico and Tec de Monterrey has solved a 2,000-year-old optical problem—the Wasserman-Wolf problem -- that will lead to cheaper & sharper lenses. https://www.osapublishing.org/ao/fulltext.cfm?uri=ao-58-4-1010&id=404342 17 comments science
- Stanford researchers have come up with a recipe for creating a microscopic crystal structure that can hold two wavelengths of light at once. This is a step toward faster telecommunications and quantum computers. https://www.osapublishing.org/optica/abstract.cfm?uri=optica-6-8-1039 3 comments science
