Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.

Optical Detection of Volatile Organic Compounds: A Review of Methods and Functionalized Sensing Materials

open access: yesAdvanced Optical Materials, EarlyView.
The focus on volatile organic compounds (VOCs) detection is dictated by the increasing awareness of their impact on human health. In addition, VOCs are increasingly considered novel for early diagnosis of diseases. Among various types of VOC sensor devices, optical detectors play an essential role, offering excellent versatility, fast response time ...

Unraveling the Role of Surfactants in Micelle‐Templated Growth of Chiral Plasmonic Nanoparticles

open access: yesAdvanced Optical Materials, EarlyView.
Micelle template‐directed growth enables precise control over the chiroptical properties of gold nanorods. Comparison of surfactants with varying aliphatic tail lengths shows that longer tails increase groove inclination and reduce groove density. Optimized conditions for the longest‐tail surfactant (C18) yield slightly higher g‐factors than those ...

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

open access: yesAdvanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...
