Astronomers and amateurs alike know the bigger the telescope, the more powerful the imaging capability. To keep the power but streamline one of the bulkier components, a Penn State-led research team created the first ultrathin, compact…

A research team co-led by City University of Hong Kong (CityU) have successfully developed a novel Vacuum Ultra-Violet (VUV) meta-lens which can generate and focus the VUV light, a disruptive technology for the UV optics market. VUV is used…

Compact and lightweight metasurfaces -- which use specifically designed and patterned nanostructures on a flat surface to focus, shape and control light -- are a promising technology for wearable applications, especially virtual and…

Rice University photonics researchers have created a potentially disruptive technology for the ultraviolet optics market. By precisely etching hundreds of tiny triangles on the surface of a microscopic film of zinc oxide, nanophotonics…

Metasurfaces are nanoscale structures that interact with light. Today, most metasurfaces use monolith-like nanopillars to focus, shape and control light. The taller the nanopillar, the more time it takes for light to pass through the…
