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 ...

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, EarlyView.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils

Small, EarlyView.
Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...

Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

Small, EarlyView.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...
