Optical Self‐Tuning of Ferroelectric Metasurfaces Infiltrated with Nematic Liquid Crystals via Photovoltaic Effect

Advanced Optical Materials, EarlyView.
A novel scheme is introduced to achieve optical self‐tuning in ferroelectric lithium niobate (LN) metasurfaces equipped with a thin film of liquid crystals (LCs). The resonant optical field distributions inside the meta‐atoms can induce a photovoltaic (PV) field, which reorients the surrounding LCs.

Supramolecular Design of Polymeric Random Lasers

Advanced Optical Materials, EarlyView.
This research investigates the application of PolyHIPE scaffolds as scattering media inRLs. By modifying the scaffold's morphology, pore size, and surface chemistry, the dye distribution within the material is precisely controlled, achieving a tunable laser threshold.

Spin‐Orbit Photonics with Potato Starch Lenses

Advanced Optical Materials, EarlyView.
Native potato starch spherulites are introduced as volumetric optical elements that modulate both dynamic and geometric phases of light. These spherulites focus light and generate optical vortices via spin‐orbit interaction, functioning as polarization‐sensitive microlenses. Their unique radial anisotropy enables applications in vortex beam generation,

Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles

Advanced Optical Materials, EarlyView.
Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.

Self‐Aligned Waveguide Array Integrated with Flat Microlenses for Environment‐Adaptive and High‐Resolution Compound Eye Vision

Advanced Optical Materials, EarlyView.
For an amphibious high‐resolution compound eye vision system, environment‐adaptive self‐aligned waveguides are integrated with high‐density flat microlenses. Fabrication, optical performance, and environmental adaptability are investigated, demonstrating stable focusing, efficient light collection, and enhanced spatial resolution.
