Journal ArticleDOI
Dielectric metasurfaces for complete control of phase and polarization with subwavelength spatial resolution and high transmission
TL;DR: A metasurface platform based on high-contrast dielectric elliptical nanoposts that provides complete control of polarization and phase with subwavelength spatial resolution and an experimentally measured efficiency ranging from 72% to 97%, depending on the exact design.
Journal ArticleDOI
Subwavelength-thick Lenses with High Numerical Apertures and Large Efficiency Based on High Contrast Transmitarrays
TL;DR: P polarization-insensitive, micron-thick, high-contrast transmitarray micro-lenses with focal spots as small as 0.57 λ are reported, thus enabling widespread adoption and a rigorous method for ultrathin lens design is discussed.
Journal ArticleDOI
Miniature optical planar camera based on a wide-angle metasurface doublet corrected for monochromatic aberrations
Amir Arbabi,Ehsan Arbabi,Seyedeh Mahsa Kamali,Yu Horie,Seung-hoon Han,Seung-hoon Han,Andrei Faraon +6 more
TL;DR: A miniature flat camera integrating a monolithic metasurface lens doublet corrected for monochromatic aberrations, and an image sensor is demonstrated with nearly diffraction-limited image quality, indicating the potential of this technology in the development of optical systems for microscopy, photography, and computer vision.
Journal ArticleDOI
MEMS-tunable dielectric metasurface lens.
Ehsan Arbabi,Amir Arbabi,Amir Arbabi,Seyedeh Mahsa Kamali,Yu Horie,MohammadSadegh Faraji-Dana,Andrei Faraon +6 more
TL;DR: In this paper, the authors demonstrate tunable metasurface doublets, based on microelectromechanical systems (MEMS), with more than 60 diopters (about 4%) change in the optical power upon a 1-μm movement of one metasuran, and a scanning frequency that can potentially reach a few kHz.
Journal ArticleDOI
A review of dielectric optical metasurfaces for wavefront control
TL;DR: In this article, a review of the recent developments in dielectric structures for shaping optical wavefronts is presented with an outlook on future potentials and challenges that need to be overcome.
