Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures

Laser &Photonics Reviews, EarlyView.
A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency

A Reversible Clearing Strategy Enables Robust Label‐Free Phase Imaging of Thick Tissues

Laser &Photonics Reviews, EarlyView.
The principle of a reversible clearing strategy via glycerol and tartrazine solution (GTS) for robust whole‐slide label‐free phase imaging of thick tissue slices via high‐throughput Fourier ptychographic microscopy (FPM) and lensless digital holographic microscopy (LDHM). ABSTRACT Thick biological specimens impose strong scattering and attenuation that

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

Laser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Engineering Photonic Pigments From Titania–Block Copolymer Composites

Macromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.
