Extreme Optics: Inverse Design and Experimental Realizations of Ultra-Large-Area Complex Meta-Optics

We present a design framework for metasurface that uses a hybrid approximate solver for Maxwell’s equations, which separates the computation for the metasurface’s nanoscale and macro-scale, and thus makes large-diameter inverse design tractable on a laptop. We further demonstrate experimental realizations of ultra-large-area metasurfaces designed using this framework: (1) a lens with extended depth of field with a millimeter diameter, and (2) polychromatic lenses with diameters of up to 1 cm.
