Nanophotonic devices, composed of metals, dielectrics or semiconductors, enable precise and high-spatial-resolution manipulation of electromagnetic waves by leveraging diverse light-matter interaction mechanisms at sub-wavelength length scales. Their compact size, light weight, versatile functionality and unprecedented performance are rapidly revolutionizing how optical devices and systems are constructed across the infrared, visible and ultraviolet spectra. Here, we review recent advances and future opportunities of nanophotonic elements operating in the ultraviolet region, which include plasmonic devices, optical metamaterials, and optical metasurfaces. We discuss their working principles, material platforms, fabrication and characterization techniques, followed by representative device applications in different areas such as imaging, sensing, spectroscopy, and wavefront shaping. We conclude this review by elaborating future opportunities and challenges of ultraviolet nanophotonic devices.
