Helical Ladder Oligomers Exhibit Amplified Circularly Polarized Emission

Advanced Optical Materials, EarlyView.
The discovery that a multi‐helicene system based on a series of annulated [6]helicenes and perylenediimides, exhibits larger‐than‐linear amplification of glum with helicene length is described. It is also observed large enhanced fluorescent quantum yields and large extinction coefficients for this length series.

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.

Exploring the Role of Artificial Intelligence in Precision Photonics: A Case Study on Deep Neural Network‐Based fs Laser Pulsed Parameter Estimation for MoOx Formation

Advanced Photonics Research, EarlyView.
Ultrafast pulsed laser technology enables precise material processing. This study examines molybdenum oxide formation under varying laser parameters. A dataset of 187 samples is generated, and eight deep neural networks (DNNs) with different architectures are trained. Models are validated using three learning rates and evaluated with mean squared error,
