Twist-Reconfigurable van der Waals Moiré Photonic Crystals
Hugo Quard, Jiyun Kim, Anastasiia Zalogina +7
Moiré photonics has emerged as a fascinating concept to design and in situ control of the optical bands. Moiré enabled light localisation arises from the relative twist between per…
Near-Field Characterisation of Guided Modes in WS2 Nanobeams and Quasi-Bulk Crystals
Zara S. Taylor, Luke M. Hallacy, Xuerong Hu +7
The exceptionally high in-plane refractive index, low sub-bandgap absorption, and strong optical anisotropy of WS2 make it a promising material platform for next-generation integra…
Magnetic switching of exciton lifetime in CrSBr
Ina V. Kalitukha, Ilya A. Akimov, Mikhail O. Nestoklon +13
Exciton dynamics in layered magnetic semiconductors provide a sensitive probe of the interplay between spin order and light-matter interaction. Here, we study thin CrSBr layers usi…
Polarization- and time-resolved nonlinear multi-photon spectroscopy for confocal microscopy of semiconductor nanostructures
Nikita V. Siverin, Andreas Farenbruch, Dmitri R. Yakovlev +4
We present a versatile confocal microscopy setup for optical second harmonic generation (SHG) and multi-photon spectroscopy that enables polarization-resolved studies of semiconduc…
Exciton-polaritons in a monolayer semiconductor coupled to van der Waals dielectric nanoantennas on a metallic mirror
Yadong Wang, Charalambos Louca, Sam Randerson +8
Polaritons in nanophotonic structures have attracted long-standing interest owing to their fundamental importance and potential for applications in nonlinear and quantum optics. Na…
Topological Jackiw-Rebbi States in Photonic Van der Waals Heterostructures
Sam A. Randerson, Paul Bouteyre, Xuerong Hu +9
Topological phenomena, first studied in solid state physics, have seen increased interest for applications in nanophotonics owing to highly controllable light confinement with inhe…
