Differentiable Fast Far-Field Transform in Cylindrical Coordinates for Large-Area Cascaded Metalens Optics
Arvin Keshvari, Ata Shakeri, William Tuxbury +4
We present a fully differentiable far-field transform in cylindrical coordinates for full-area point spread function (PSF) evaluation and optimization of large axisymmetric metalen…
Heterogeneous Freeform Metasurfaces: A Platform for Advanced Broadband Dispersion Engineering
Zhaoyi Li, Sawyer D. Campbell, Joon-Suh Park +4
Metasurfaces, with their ability to control electromagnetic waves, hold immense potential in optical device design, especially for applications requiring precise control over dispe…
Free-standing bilayer metasurfaces in the visible
Ahmed H. Dorrah, Joon-Suh Park, Alfonso Palmieri +1
Mult-layered meta-optics have enabled complex wavefront shaping beyond their single layer counterpart owing to the additional design variables afforded by each plane. For instance,…
All-glass 100 mm Diameter Visible Metalens for Imaging the Cosmos
Joon-Suh Park, Soon Wei Daniel Lim, Arman Amirzhan +8
Metasurfaces, optics made from subwavelength-scale nanostructures, have been limited to millimeter-sizes by the scaling challenge of producing vast numbers of precisely engineered…
Point singularity array with metasurfaces
Soon Wei Daniel Lim, Joon-Suh Park, Dmitry Kazakov +4
Phase singularities are loci of darkness surrounded by monochromatic light in a scalar field, with applications in optical trapping, super-resolution imaging, and structured light-…
All-Optical tunability of metalenses infiltrated with liquid crystals
Giovanna Palermo, Andrew Lininger, Alexa Guglielmelli +8
Metasurfaces have been extensively engineered to produce a wide range of optical phenomena, allowing unprecedented control over the propagation of light. However, they are generall…
Inverse design enables large-scale high-performance meta-optics reshaping virtual reality
Zhaoyi Li, Raphaël Pestourie, Joon-Suh Park +3
Meta-optics has achieved major breakthroughs in the past decade; however, conventional forward design faces challenges as functionality complexity and device size scale up. Inverse…
