  bibo_abstract:
  - We demonstrate new axisymmetric inverse-design techniques that can solve problems
    radically different from traditional lenses, including reconfigurable lenses (that
    shift a multi-frequency focal spot in response to refractive-index changes) and
    widely separated multi-wavelength lenses (λ = 1 µm and 10 µm). We also present
    experimental validation for an axisymmetric inverse-designed monochrome lens in
    the near-infrared fabricated via two-photon polymerization. Axisymmetry allows
    fullwave Maxwell solvers to be scaled up to structures hundreds or even thousands
    of wavelengths in diameter before requiring domain-decomposition approximations,
    while multilayer topology optimization with ∼105 degrees of freedom can tackle
    challenging design problems even when restricted to axisymmetric structures.@eng
