Microlasers Made Entirely from Edible Substances

Advanced Optical Materials, EarlyView.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Rapid Electro‐Thermal Micro‐Actuation of Flat Optics Enabled by Laser‐Induced Graphene on Colorless Polyimide Substrates

Advanced Optical Materials, EarlyView.
Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters

Advanced Optical Materials, EarlyView.
Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.

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.

Cation‐Engineered Post‐Treatment for Blue Perovskite Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
This work presents a cation‐engineered post‐treatment strategy for high‐performance mixed‐halide blue PeLEDs. By investigating the role of 4‐fluorophenylethylammonium (FPEA+) versus conventional phenylethylammonium (PEA+) organic cations in post‐treatment agents, it demonstrates that FPEA+ enables superior preservation of the 3D perovskite structure ...

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,

Graphene as Infrared and Electron Transparent Electrode Applied to the Design of Narrow Bandgap Nanocrystal‐Based Photodiode

Advanced Optical Materials, EarlyView.
The article explores the need for transparent conductive electrode in the context of nanocrystal based infrared photodetectors beyond traditional transparent conductive oxide and metallic grids. Use of such sensor for imaging where the diode is deposited on a read‐out integrated circuit raised the need for top transparent electrode.
