A multi-GHz chaotic optoelectronic oscillator based on laser terminal voltage [PDF]
Appl. Phys. Lett. 108, 191109 (2016), 2017 A multi-GHz chaotic optoelectronic oscillator based on an external cavity semiconductor laser (ECL) is demonstrated. Unlike standard optoelectronic oscillators for microwave applications, we do not employ the dynamic light output incident on a photodiode to generate the microwave signal, but instead generate the microwave signal directly by measuring ...

Accelerated Discovery of Two-Dimensional Optoelectronic Octahedral Oxyhalides via High-Throughput Ab Initio Calculations and Machine Learning [PDF]
, 2019 Traditional trial-and-error methods are obstacles for large-scale searching of new optoelectronic materials. Here, we introduce a method combining high-throughput ab initio calculations and machine-learning approaches to predict two-dimensional octahedral oxyhalides with improved optoelectronic properties. We develop an effective machine-learning model

Plasma‐Induced Maskless Formation of Quasi‐Periodic Nanoripples on Polymeric Substrates
Advanced Engineering Materials, Volume 27, Issue 7, April 2025.Reactive plasma etching is proposed for maskless, rapid, mass‐production of quasi‐periodic nanoripples formed on the area adjacent to the electrode of polymeric substrates perpendicularly placed on the electrode. To this end, a modeling framework is employed for the calculation of particle trajectories, which predicts the angular and energy ...
