MEMS-tunable dielectric metasurface lens
Conventional refractive elements are bulky, thick and offer limited active tunability. Here, the authors demonstrate MEMS-based tunable metasurface doublets with more than 60 diopters change in the optical power upon a 1-micron movement of a membrane with one of the metasurface elements.
