Engineering Thermal Emission with Enhanced Emissivity and Quality Factor Using Bound States in the Continuum and Electromagnetically Induced Absorption

Advanced Optical Materials, EarlyView.
A metal‐based thermal metasurface supporting bound states in the continuum is demonstrated and experimentally shown to achieve a record‐high quality factor of 202 and high emissivity of 0.82. The design offers thermally stable, narrowband mid‐infrared emission, making it ideal for high‐precision gas sensing applications.

Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

Advanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.

Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

Advanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

Advanced Optical Materials, EarlyView.
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.

Quasi‐Bound States in the Continuum on the Bloch‐Surface‐Wave Platform for Sensing With Simultaneous High Q‐Factor and High Sensitivity

Advanced Optical Materials, EarlyView.
Quasi‐bound states in the continuum on the Bloch surface wave platform are demonstrated, exhibiting high Q‐factors due to strongly suppressed radiative losses and high sensitivity arising from the large evanescent field inherent to the surface wave. The resonance shows clear shifts after each surface molecular functionalization step, highlighting its ...
