Thesis: S.M., Massachusetts Institute of Technology, Department of Materials Science and Engineering, February, 2021 Cataloged from the official PDF of thesis. Includes bibliographical references (pages 47-50). Achromatic and wide field-of-view (WFOV) optical functionalities are desired for various imaging applications. Conventional methods use complicated design approaches or assemble multiple optical components to form achromatic and WFOV lenses. They are bulky and have limited focusing quality. Here a novel metalens design is presented which shows extraordinary achromatic and WFOV focusing quality simultaneously. The metalens is composed of all-dielectric meta-atoms selected from a large meta-atoms library with diverse dispersion behavior. The metalens and an aperture are integrated on opposite sides of the substrate to separate areas with different angle-of- incidents (AOIs). A theoretical analysis and a direct search algorithm are combined to obtain optimum phase profile of metalens. This design concept is generic and can be applied to lenses with different parameters to meet the demands of various applications. by Fan Yang. S.M. S.M.
