Effects of Mineralogical Inhomogeneity on Aggregate Dust Optical Properties and Lidar Observables

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Dust aerosols comprise irregular grains and aggregates with various mineralogical mixtures. However, most optical models use effective refractive indices to represent particles. This study develops an inhomogeneous aggregate model assigning mineral‐dependent refractive indices to constituent elements and representing global mineral volume ...

Integration of hBN Single‐Photon Emitters Into a Hybrid Optomechanical Membrane‐In‐The‐Middle Fiber‐Cavity

open access: yesNanophotonics, Volume 15, Issue 19, 13 October 2026.
Deterministic manipulation of hexagonal boron nitride (hBN) flakes enables single‐photon emitters (SPEs) to be integrated into a fiber‐based Fabry–Pérot membrane‐in‐the‐middle cavity. Cavity coupling enhances and spectrally funnels the broadband emitter fluorescence, while allowing access to mechanical membrane modes for future hybrid optomechanical ...

Sparse‐Aperture Quasi‐Achromatic Spintronic Terahertz Emitter Enabled by Binary‐Phase Metasurface and Multi‐Spectral Intensity Optimization

open access: yesNanophotonics, Volume 15, Issue 19, 13 October 2026.
We propose a sparse‐aperture shared‐aperture design with multispectral intensity optimization, enabling a Pt/W binary‐phase metasurface directly integrated with a spintronic emitter. The device achieves quasi‐achromatic focusing across 1.0–1.5 THz, with intensity fluctuation below 33% and edge preservation above 0.68.

Enhanced Ferroelectric Phase Formation via Local Structure Modification in the Pre‐Crystalline State of Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, Volume 36, Issue 80, 5 October 2026.
Hafnium zirconium oxide thin films are grown using plasma‐enhanced atomic layer deposition with the addition of an atomic layer annealing (ALA) step. ALA leads to a change in the short‐range structure of the deposit and encourages formation of the ferroelectric Pca21 phase. The result is wake‐up‐free performance with films exposed to ALA.

Wavelength‐Multiplexed 2D Beam Steering via a Passive Diffractive Network

open access: yesAdvanced Optical Materials, Volume 14, Issue 37, 9 October 2026.
Illustration of a wavelength‐multiplexed diffractive beam steering system, which is composed of K cascaded diffractive layers, each containing phase‐modulating elements that are jointly optimized using deep learning–based optimization. When illuminated with a set of wavelengths {λ1,λ2,…,λNw}$\{ {{{\lambda }_1},{{\lambda }_2},\ldots ,{{\lambda }_{{{N}_w}
