3D Printed Multilayer Structures for High Numerical Aperture Achromatic Metalenses
Cheng-Feng Pan, Hao Wang, Hongtao Wang +8
Flat optics consisting of nanostructures of high-refractive-index materials produce lenses with thin form factors that tend to operate only at specific wavelengths. Recent attempts…

Twist-angle and thickness-ratio tuning of plasmon polaritons in twisted bilayer van der Waals films
Chong Wang, Yuangang Xie, Junwei Ma +13
Stacking bilayer structures is an efficient way to tune the topology of polaritons in in-plane anisotropic films, e.g., by leveraging the twist angle (TA). However, the effect of a…

An entropy-controlled objective chip for reflective confocal microscopy with subdiffraction-limit resolution
Jun He, Dong Zhao, Hong Liu +3
Planar lenses with optimized but disordered structures can focus light beyond the diffraction limit. However, these disordered structures have inevitably destroyed wide-field imagi…
