Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix
Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

Advanced Optical Materials, EarlyView.For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces
Advanced Optical Materials, EarlyView.Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...

Spin‐Valley Polarization Control in WSe2 Monolayers using Photochemical Doping
Advanced Optical Materials, EarlyView.A photochemical doping method is employed to modulate the spin‐valley polarization in WSe2 monolayers by tuning the carrier density from electron‐rich to hole‐rich regimes. This controlled doping enables a three‐fold variation in exciton polarization, revealing relaxation channels driven by scattering between excitons and charge carriers in two ...

Advanced Optical Materials, EarlyView.Compression to ≈2.0 GPa results in a non‐monotonic enhancement of the Pb‐I bond distortion, rarely observed in other 2D lead‐iodide hybrid perovskites. The octahedral distortion together with the rigidity of spacer cation are found to play a dominant role in determining the optoelectronic properties of DPDAPbI4 under high pressure.

Advanced Optical Materials, EarlyView.Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...
