The demand for compact and high-performance optical devices in the short-wave infrared (SWIR) region continues to grow, driven by applications ranging from molecular spectroscopy to advanced sensing technologies. Yan He and Adetunmise Dada, from the University of Glasgow, and their colleagues present a new metalens design that addresses key limitations of conventional optics in this crucial spectral band. Their research overcomes the challenges of chromatic aberration and bulky components by utilising subwavelength nanostructures to precisely control light, achieving stable fo…
