Both 2D and 3D axisymmetric designs are presented, optimized over ∼105 degrees of freedom. We also demonstrate shortening the lens-to-sensor distance while producing the same image as for a longer “virtual” focal length and maintaining plan-achromaticity. These proof-of-concept designs demonstrate the ultra-compact multifunctionality that can be achieved by exploiting the full wave physics of subwavelength designs and motivate future work on design and fabrication of multilayer metaoptics.","lang":"eng"}],"title":"Computational inverse design for ultra-compact single-piece metalenses free of chromatic and angular aberration","type":"journal_article","intvolume":"       118","status":"public","year":"2021","volume":118,"issue":"4","publisher":"AIP Publishing","publication_status":"published","language":[{"iso":"eng"}],"scopus_import":"1","day":"27","arxiv":1,"publication_identifier":{"issn":["0003-6951"],"eissn":["1077-3118"]},"citation":{"mla":"Lin, Zin, et al. “Computational Inverse Design for Ultra-Compact Single-Piece Metalenses Free of Chromatic and Angular Aberration.” <i>Applied Physics Letters</i>, vol. 118, no. 4, 041104, AIP Publishing, 2021, doi:<a href=\"https://doi.org/10.1063/5.0035419\">10.1063/5.0035419</a>.","ieee":"Z.
