Patent number: 11977221Abstract: An optical device for aberration correction (e.g., chromatic aberration correction) is disclosed. The optical device includes an optical component (e.g., a spherical lens) and a metasurface optically coupled to the optical component. The metasurface includes a plurality of nanostructures that define a phase profile. The phase profile corrects an aberration (e.g., chromatic aberration) caused by the optical component. The resulting optical device becomes diffraction-limited (e.g., for the visible spectrum) with the metasurface.Type: GrantFiled: February 19, 2019Date of Patent: May 7, 2024Assignee: PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Wei-Ting Chen, Alexander Yutong Zhu, Jared F. G. Sisler, Federico Capasso
