Rotational varifocal moiré metalens made of single-crystal silicon meta-atoms for visible wavelengths
Metasurface lenses (metalenses) offer an ultrathin and simple optical system with dynamic functions that include focal length tuning. In this study, a rotational varifocal (i.e., moiré) metalens based on octagonal single-crystal silicon pillars was designed and fabricated to realize a high transmitt...
