Stacked Time‐Varying Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Stacked, spatially uniform, time‐modulated metasurfaces replace cumbersome in‐plane modulation. A general design framework optimizes independently programmed temporal functions across cylindrical meta‐atom arrays with time‐varying plasma/collision frequencies, yielding magnet‐free isolation at the carrier and a temporal circulator analogue.

Diameter Dependence of Light Absorption in GaAs Nanowires Evidenced by Photoluminescence Spectroscopy

open access: yesAdvanced Optical Materials, EarlyView.
Photoluminescence spectroscopy is introduced as a qualitative method to probe light absorption in highly phase‐pure GaAs nanowire arrays and single nanowires, for which direct absorption measurements are challenging. Using defect‐line saturation and the exciton‐to‐plasma transition as indicators for the density of photogenerated charge carriers, a ...

Photonics of Topological Magnetic Textures

open access: yesAdvanced Optical Materials, EarlyView.
Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...
