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.

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Advanced Photonics Research, EarlyView.Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Advanced Photonics Research, EarlyView.This study demonstrates a label‐free optical method to monitor cells using a terahertz metasurface‐based biosensing platform. The obtained terahertz signal change for the cell‐contained nanoslots before and after external stimulus is analyzed in terms of transmittance and frequency shift, dynamically representing the cell apoptosis process.

Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings
Advanced Photonics Research, EarlyView.The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms
Advanced Photonics Research, EarlyView.A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion
