Antireflection by design in bilayer metasurfaces
Jaewon Oh, Davide Cassara, Alfonso Palmieri +5
Antireflection coatings are ubiquitous in optical systems, where they maximize transmission and suppress undesirable reflections by impedance-matching uniform interfaces. Extending…
Topology-Optimized Dielectric Cavities for Enhanced Excitonic Light Emission from
Owen Matthiessen, Brandon Triplett, Omer Yesilyurt +14
Photonic inverse design and, especially, topology optimization, enable dielectric cavities with deeply sub-diffraction mode volumes and high quality factors, thus offering a powerf…
Filterless Snapshot Hyperspectral Imaging using Guided Patch Diffusion
Dean Hazineh, Luca Sacchi, Davide Cassara +2
We consider the problem of reconstructing a HxWx31 hyperspectral image from a grayscale snapshot measurement that is captured using only a single diffractive lens and a…
Shape optimization for high efficiency metasurfaces: theory and implementation
P. Dainese, L. Marra, D. Cassara +7
Complex non-local behavior makes designing high efficiency and multifunctional metasurfaces a significant challenge. While using libraries of meta-atoms provide a simple and fast i…
