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…
Nonlinear multi-frequency phonon lasers with active levitated optomechanics
Tengfang Kuang, Ran Huang, Wei Xiong +8
Phonon lasers, exploiting coherent amplifications of phonons, have been a cornerstone for exploring nonlinear phononics, imaging nanomaterial structures, and operating phononic dev…
Colorful Optical Vortices with White Light Illumination
Hongtao Wang, Hao Wang, Qifeng Ruan +8
The orbital angular momentum (OAM) of light holds great promise for applications in optical communication, super-resolution imaging, and high-dimensional quantum computing. However…
Quadrupole Topological Insulator in Non-Hermitian Thermal Diffusion
Guoqiang Xu, Xue Zhou, Jing Wu +1
Quantized bulk quadrupole moment has unveiled a nontrivial boundary state, exhibiting lower-dimensional topological edge states and simultaneously hosting the in-gap corner modes o…
