Methodology for Topological Interface Engineering in 2D Photonic Crystals

Advanced Photonics Research, EarlyView.
This article introduces an automated framework for topological photonic crystal design. It features an iterative band connection method for identifying band crossings, a data‐driven approach for band symmetry recognition, and analysis of how topological mode dispersion trades off with photonic band‐gap size.

Impact of System‐Model Mismatch in Fourier Ptychographic Microscopy

Advanced Photonics Research, EarlyView.
This study investigates the robustness of Fourier ptychography microscope (FPM) reconstruction algorithms across various scenarios, each representing challenges encountered in practical FPM experiments, and deduces the extent to which FPM can provide diffraction‐limited resolution under the influence of various sources of error.

Metasurface‐Encoded Single‐Pixel Hyperspectral Imaging

Advanced Photonics Research, EarlyView.
A metasurface‐enabled single‐pixel hyperspectral imaging approach is proposed, achieving sub‐2‐nanometer spectral discrimination and accurate reconstruction at low sampling ratios. By uniting advanced nanophotonics with data‐driven algorithms, this framework overcomes limitations of conventional single‐pixel imaging and sets a new benchmark for compact

Techniques and Advances in Ultrafast Photography

Advanced Photonics Research, EarlyView.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...
