The Impact of Donor‐Orientation on the Emission Properties of Chlorinated Trityl Radicals

open access: yesAdvanced Optical Materials, EarlyView.
Chlorinated trityl radicals with electron‐donating groups enable efficient red emission for optoelectronics. Donor orientation and steric constraints regulate vibronic coupling, influencing luminescence. A novel trityl derivative with restricted donor alignment minimizes non‐radiative decay, enhancing quantum yield.

Angle‐ and Polarization‐Tolerant Metasurface Designs Based on the Aperiodic Tiling

open access: yesAdvanced Optical Materials, EarlyView.
A novel aperiodic metasurface design is introduced to mitigate the inherent angle and polarization sensitivity of conventional metasurfaces. By employing a recently discovered aperiodic tiling approach, identical elliptical scatterers are arranged with systematic variations in their spacing and orientation, effectively minimizing spectral reflectance ...

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

open access: yesAdvanced 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,
