In article number 2001388, Yupeng Zhang, Baohua Jia, Qiaoliang Bao, and co‐workers develop flat lenses based on 2D perovskite nanosheets using a cost‐effective mask‐free femtosecond direct laser writing system. The tunable material property affords effective manipulation of both amplitude and phase of the incident light, which is focused into a subwavelength 3D spot with a resolution in the range...
Ultrathin flat lenses based on metasurfaces or metamaterials have shown great promise in recent years as essential components in nano‐optical system, with capability of abrupt changes of light wavefronts. However, such structural designs require complex nanopatterns and a time‐consuming nanofabrication process. In this regard, flat lenses are developed based on 2D perovskite nanosheets, using a cost‐effective...
