Narrow Linewidth Spontaneous and Lasing Emissions from Open‐Access Microcavity‐Embedded Perovskite Quantum Dots

open access: yesAdvanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

A Fiber‐Optic Surface‐Enhanced Raman Scattering (SERS) Probe for Sensitive Endotoxin Detection with Reduced Limulus Amebocyte Lysate (LAL) Consumption

open access: yesAdvanced Sensor Research, Volume 5, Issue 1, January 2026.
Current gold‐standard endotoxin detection relies on Limulus Amebocyte Lysate (LAL) reagents, yet this approach suffers from unsustainable exploitation of Limulus resources. Here, we developed a fiber‐optic Surface‐enhanced Raman scattering (SERS) probe that enables highly sensitive endotoxin detection with drastically reduced LAL consumption.

Ultrasensitive Diamond Cantilever‐Based Optical Microphone

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...
