In this episode: New filter tech boosts night vision, a new design aids UV meta-holograms, and thin-film membranes confine IR light.

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.
