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 ...

Frequency and phase locking of laser cavity solitons

, 2012
Self-localized states or dissipative solitons have the freedom of translation in systems with a homogeneous background. When compared to cavity solitons in coherently driven nonlinear optical systems, laser cavity solitons have the additional freedom of ...

Efficient optoelectronic de-embedding for VCSEL intrinsic response extraction [PDF]

, 2010
In this present work, we propose a new method to remove the parasitics contribution to the VCSEL chip response,in order to obtain the intrinsic transmission behavior. It has been observed that the S11 reflection coefficient of the chip is only due to the

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.
