Optical Responses From Zero Optical‐Path‐Length Object

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Compact Snapshot Hyperspectral Imaging With Neural Dispersion‐Engineered Metalens

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
A dispersion‐engineered metalens, designed via an end‐to‐end deep learning framework, encodes spectral information through wavelength‐dependent PSF shifts. Fabricated by two‐photon grayscale lithography, the ultrathin device demonstrates outstanding spatial‐spectral reconstruction in both indoor and outdoor scenes, positioning it as a promising ...

Self‐Assembled Calcite Architectures for Programmable Information Storage

Advanced Materials Technologies, Volume 11, Issue 16, 21 August 2026.
Programmable biomineralization enables the formation of 3D calcite architectures that encode information through spatially defined refractive‐index modulations. Data are written via laser‐directed mineralization, stored in stable voxelized mineral structures, and retrieved non‐destructively through optical diffraction, offering a pathway toward ultra ...

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams

Advanced Optical Materials, Volume 14, Issue 31, August 21, 2026.
Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.

Integrated Ultrasonic Platform for Bioelectronic Control through Biological Barriers Based on Metasurface

Advanced Science, Volume 13, Issue 43, 3 August 2026.
A metasurface‐enabled ultrasonic platform achieves precise multi‐focal control through biological barriers, real‐time physiology‐driven modulation, and simultaneous wireless power and data transmission. By unifying wavefront engineering, closed‐loop feedback, and acoustic communication, this work establishes key enabling technologies toward scalable ...
