Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs

Advanced Optical Materials, EarlyView.
The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...
