  text: Optical metasurfaces have been heralded as the platform to integrate multiple
    functionalities in a compact form-factor, with the potential to replace bulky
    optical components. A central stepping stone toward realizing this promise is
    the demonstration of multifunctionality under several constraints (e.g., at multiple
    incident wavelengths and/or angles) in a single device, an achievement being hampered
    by design limitations inherent to single-layer planar geometries. Here, we propose
    a framework for the inverse design of multilayer metaoptics via topology optimization,
    showing that even few-wavelength thick devices can achieve high-efficiency multifunctionality,
    such as multiangle light concentration and plan-achromaticity. We embody our framework
    in multiple closely spaced patterned layers of a low-index polymer, with fabrication
    constraints specific to this platform enforced in the optimization process. We
    experimentally demonstrate our approach with an inverse-designed 3D-printed light
    concentrator working at five different nonparaxial angles of incidence. Our framework
    paves the way toward realizing multifunctional ultracompact 3D nanophotonic devices.
