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…
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…
Stability of variable-step BDF2 and BDF3 methods
Zhaoyi Li, Hong-lin Liao
We prove that the two-step backward differentiation formula (BDF2) method is stable on arbitrary time grids; while the variable-step BDF3 scheme is stable if almost all adjacent st…
End-to-end metasurface inverse design for single-shot multi-channel imaging
Zin Lin, Raphaël Pestourie, Charles Roques-Carmes +4
We introduce end-to-end metaoptics inverse design for multi-channel imaging: reconstruction of depth, spectral and polarization channels from a single-shot monochrome image. The pr…
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…
