New paper in Nanophotonics describes visible-to-near infrared metalens

U.K. graduate students Fatih Balli and Mansoor Sultan just published their work on "flat optics" in Nanophotonics.  Their paper, "An Ultrabroadband 3D Achromatic Metalens," describes lenses 50 times thinner than a human hair.  The lenses image with light ranging from blue (450 nm) to the short-wave infrared (1700 nm).  The compact size, light weight, and mass manufacturabilty of metalenses make them ideal for mobile and airborne imaging.  The broadband capabilities of this lens are particularly well suited to emerging visible-to-short wave infrared camera technology.
