Vacuum UV metalens illustration (IMAGE) Rice University Caption By precisely etching hundreds of tiny triangular nanoresonators in precisely configured concentric circles on a microscopic film of zinc oxide, photonics researchers at Rice University created a “metalens,” a transparent, solid-state device thinner than a sheet of paper that bends light like a conventional lens. Rice’s metalens converts 394-nanometer ultraviolet light (blue) into 197-nanometer “vacuum UV” (pink) and simultaneously focuses the VUV output on a small spot less than 2 millionths of a meter in diameter.
