Metalenses can integrate the functionalities of multiple optical components thanks to the unprecedented capability of optical metasurfaces in light control.With the rapid development of optical metasurfaces,metalenses continue to evolve.Polarization and color play a very important role in understanding optics and serve as valuable tools for gaining insights into our world.Benefiting from the design flexibility of metasurfaces,we propose and experimentally demonstrate a super metalens that can realize multifaceted control of focal points along any 3D curved trajectory.The wavelengths and polarization states of all focal points are engineered in a desirable manner.The super metalens can simultaneously realize customized 3D positioning,polarization states,and wavelengths of focal points,which are experimentally demonstrated with incident wavelengths ranging from 501 to 700 nm.We further showcase the application of the developed super metalenses in 3D optical distance measurement.The compact nature of metasurfaces and unique properties of the proposed super metalenses hold promise to dramatically miniaturize and simplify the optical architecture for applications in optical metrology,imaging,detection,and security.
