Deep‐UV Photonic Crystal Surface‐Emitting Lasers

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
The first deep‐UV photonic crystal surface‐emitting lasers (PCSELs) at 279 nm are demonstrated under pulsed optical pumping. The PCSELs have single‐mode emission with a 17‐pm linewidth and a divergence angle of less than 1∘$^{\circ }$. Experimental results highlight the impact of the filling factor choice on the lasing mode and the far‐field emission ...

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
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 ...

Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

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

Advanced 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.
