An enhanced infrared (IR) filter developed by a research team in Australia that uses nonlinear upconversion and is based on a non-local lithium niobate metasurface could bring night vision technology beyond conventional applications.
Using nanopatterning and nanoimprint lithography fabrication techniques, researchers in South Korea have made a significant breakthrough for UV metasurfaces with the discovery of the optimal conditions needed to mass-produce UV holograms.
Researchers in North Carolina have demonstrated in physically experiments a long-held theoretical idea—the confinement of IR light. It’s an advancement that’s poised to revolutionize imaging and nanophotonic technologies.
