Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

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

This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.
