Viologen phosphoric acid salt modified PEDOT:PSS for high‐performance 3D perovskite photodetectors

InfoMat, EarlyView.
A novel viologen derivative, APV, is incorporated into PEDOT:PSS to enhance the performance of 3D perovskite photodetectors. The optimized device achieves an ultra‐low dark current of 5.75 × 10−7 mA cm−2 and a large bandwidth of 1.5 MHz. Integrated into an optical wireless communication system, it achieves a data rate of 12.5 Mbps, demonstrating ...

Higher Speed Multispectral Imaging Using a Thin Liquid Crystal Layer in Metal Cavity and Artificial Intelligence Reconstruction Algorithm

Laser &Photonics Reviews, EarlyView.
A rapid multispectral imaging system is presented that integrates a 4 µm‐thick liquid crystal spectral modulator in a metal–insulator–metal (MIM) configuration with a multi‐bandpass filter (MBF). Coupled with a custom AI‐based reconstruction algorithm, the system enables accurate food quality monitoring and demonstrates the potential to capture a ...

Decoupling Optical and Thermal Dynamics in Dielectric Metasurfaces for Self‐Encoded Photonic Control

Laser &Photonics Reviews, EarlyView.
Schematic representation of transmission modulation via photo‐thermo‐optical non‐linearities in a dielectric metasurface. Abstract Thermo‐optical nonlinearities (TONL) in metasurfaces enable dynamic control of optical properties—such as transmitted power, phase, and polarization—through external stimuli like laser irradiation or temperature. Due to the

Tailoring Flatband Dispersion in Bilayer Moiré Photonic Crystals

Laser &Photonics Reviews, EarlyView.
 The photonic dispersion in 1D moiré structures formed by stacking two photonic crystal slabs with slightly different periods is experimentally investigated. By precisely adjusting the filling factor of the photonic crystals, the evolution of moiré minibands into flatbands is experimentally and numerically demonstrated. This result provides a practical
