Reversible Thermal Tuning of High‐Q Non‐Local Lithium Niobate Metasurfaces

Laser &Photonics Reviews, EarlyView.
Introducing a polarization sensor using scattering in a short optical fiber and deep learning. The breakthrough lies in sparse sampling of the scattered light and single‐photon sensitivity. The all‐fiber sensor achieves unprecedented accuracy, speed, resolution, and stability.

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

Laser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Mode‐Locked Pulse Generation in Plasmonic Lattices

Laser &Photonics Reviews, EarlyView.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...
