  bibo_abstract:
  - In this Letter, we demonstrate highly efficient, polarization-insensitive planar
    lenses (metalenses) at red, green, and blue wavelengths (λ = 660, 532, and 405
    nm). Metalenses with numerical apertures (NA) of 0.85 and 0.6 and corresponding
    efficiencies as high as 60% and 90% are achieved. These metalenses are less than
    600 nm-thick and can focus incident light down to diffraction-limited spots as
    small as ∼0.64λ and provide high-resolution imaging. In addition, the focal spots
    are very symmetric with high Strehl ratios. The single step lithography and compatibility
    with large-scale fabrication processes make metalenses highly promising for widespread
    applications in imaging and spectroscopy.@eng
