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 of 0.5‐0.9λ.
