Mode‐Locked Pulse Generation in Plasmonic Lattices

open access: yesLaser &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 ...

Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2

open access: yesLaser &Photonics Reviews, EarlyView.
A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

Superimposed Sacrificial Texturing to Enhance the Optical Performance in Thin‐Film Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Sacrificial texturing method using controlled etching of undoped zinc oxide and indium‐doped tin oxide generates microscale and nanoscale textures on glass. Roughness on two different scales is superimposed to create a new texture capable of broad‐spectrum scattering, which is utilised in thin‐film silicon solar cells to enhance optical performance ...
