Size Effect on Photothermal Heating Ability of Gold Bipyramids

open access: yesAdvanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces

open access: yesAdvanced Optical Materials, EarlyView.
Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

open access: yesAdvanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

Directionally Asymmetric Holographic Imaging for Arbitrary Polarization States Using Janus Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
We demonstrate single‐layer titanium dioxide Janus metasurface holograms that achieve directionally asymmetric imaging under forward and backward illumination. By integrating the Dammann grating principle with precise phase control, our design produces high‐fidelity holographic images for arbitrary polarization states at 532 nm, simplifying fabrication,

Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

open access: yesAdvanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.
