Abstract

In this talk, I will first show our progress on developing passive/static metalenses, which can achieve various unique functionalities such as extremely high (~0.99 in air) numerical aperture or extra-large field of view (~180°). I will also show how by combining multiple lenses and controlling their dispersion we can enable white-light imaging in the visible spectrum and hyperspectral imaging in the mid-wave IR. Finally, I will focus on tunable metasurfaces, particularly demonstrating single pixel tunability in both 1D and 2D pixel arrays, providing the first demonstration of nanoantenna spatial light modulators with ~1 micron pixel size.
