Theoretical and experimental results demonstrating reversible and irreversible regimes of light-metasurface interactions will be described. First, I will describe how all-dielectric metasurfaces can be combined with liquid crystals to develop a new class of electrically-controlled multi-focal metalenses operating at several wavelengths. New design strategies aimed at simplifying metalens fabrication and producing high-NA tunable meta-optics will be discussed. Finally, I will demonstrate how semiconductor metasurfaces enable the strongly-driven regime of laser-metasurface interactions manifested as laser-assisted material nanostructuring using femtosecond mid-infrared laser pulses.
