Self‐Assembled Monolayers Facilitate Simultaneous Enhancements of External Quantum Efficiencies and Circularly Polarized Luminescence Dissymmetry Factors for Chiral Perovskite Red Spin‐Light Emitting Diodes

open access: yesAdvanced Science, EarlyView.
With the self‐assembled monolayer (SAM), external quantum efficiencies and dissymmetry factors for circularly polarized electroluminescence are simultaneously enhanced for chiral perovskite red spin‐light emitting diodes (spin‐LEDs). These are ascribed to the improvements of magneto‐chiroptical and electronic properties.

Near‐Field Acoustic Imaging Using Fiber‐Optic Distributed Acoustic Sensing and Beamforming Techniques

open access: yesAdvanced Science, EarlyView.
This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

Topology Optimization of High‐Performance Optomechanical Resonator

open access: yesAdvanced Science, EarlyView.
Compact mechanical resonators designed to operate at higher‐order modes are presented, achieving high frequencies and enhanced quality factor‐frequency (Qf) products. Using topology optimization, edge losses are reduced and damping is improved. These resonators offer strong performance in a small footprint, making them ideal for quantum transduction ...
