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

Advanced 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.

High‐Energy Femtosecond All‐Fiber Laser Systems in 1.7–1.8 μm Using a Normal‐Dispersion Tm‐Doped Fiber

Advanced Photonics Research, EarlyView.
High‐energy ultrafast all‐fiber lasers are demonstrated in the 1.7–1.8 μm range using a novel Tm‐doped fiber with depressed cladding for dispersion tailoring and short‐pass filtering. A parabolic core enhances optical gain, overcoming poor gain overlap in conventional depressed cladding fibers.

A Compact Optical Sensor to Self‐Assess Skin Health after Sun Exposure

Advanced Sensor Research, EarlyView.
This work presents a portable, low‐cost device capable of detecting changes in the skin associated with excessive sun exposure through reflectance measurements. In vitro validation experiments in skin‐mimicking tissue phantoms showed the device can detect relative pigmentation changes as small as 5%.

Polylactic Acid (PLA), Polycaprolactone (PCL), and Chitosan: the Biodegradable Transition in Medical Waste Management

Advanced Sustainable Systems, EarlyView.
The shift to biodegradable materials in healthcare promises reduced plastic pollution, but their production, adoption, and long‐term impacts remain complex. Integrating lifecycle insights with global policy coordination is essential for meaningful environmental gains. Abstract The COVID‐19 pandemic sharply increased medical waste, intensifying concerns
