Dynamically Tunable Coherent Perfect Absorption Based on Bound States in the Continuum in Borophene Metamaterials

open access: yesAdvanced Photonics Research, EarlyView.
This article proposes a symmetry‐protected bound states in the continuum mechanism based on borophene metamaterials, achieving dual‐band broadband coherent perfect absorption (CPA) in the near‐infrared spectrum. By dynamically modulating carrier concentration, the operational bandwidth of CPA can be significantly expanded, effectively overcoming the ...

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

open access: yesAdvanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

Impact of System‐Model Mismatch in Fourier Ptychographic Microscopy

open access: yesAdvanced 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

open access: yesAdvanced 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
