Meta-optics are attracting intensive interest as alternatives to traditional optical systems comprising multiple lenses and diffractive elements. Among applications, single metalens imaging is highly attractive due the potential for achieving significant size reduction simplified design. However, metalenses exhibit severe chromatic performance degradation arising from material dispersion nature of singlet optics, making them unsuitable full-color requiring achromatic performance. In this...

Kolmogorov–Smirnov test assessed centrality differences, with cross‐validation performed the Association for Advancement...
The inverse design of meta-optics has received much attention in recent years. In this paper, we propose a GPU-friendly framework based on improved eigendecomposition-free rigorous diffraction interface theory, which offers up to 16.2 × speedup over the traditional coupled-wave analysis. We further improve framework's flexibility by introducing hybrid parameterization combining neural-implicit and shape optimization. demonstrate effectiveness our through intricate tasks, including...
Abstract Chromatic aberration has been the main showstopper for metalenses when it comes to imaging applications with broadband sources such as ambient light. In wide field‐of‐view metalenses, this challenge becomes far more severe due exacerbated lateral chromatic aberrations. paper, is demonstrated, first time, full‐color using a fisheye metalens coupled deep learning computational processing. This approach capable of restoring panoramic images enhanced signal‐to‐noise ratio while...
A multimode interference (MMI) polarization splitter with easy fabrication process was demonstrated in Silicon-On-Insulator substrate. The minimum device size, 8 µm×1034 µm designed by Quasistate imaging effect theory. Numerical simulations show that this optimized MMI has a good tolerance. tolerance of width and length is ±0.04 ± 10 for transverse electric (TE) mode ±0.14 ±35 magnetic (TM) mode. bandwidths are 20 nm 80 TE TM respectively.
