Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

Advanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Ultrabroadband Excitation of Hot Carriers in Plasmonic Nanorods Revealed by Two‐Dimensional Electronic Spectroscopy

Advanced Optical Materials, EarlyView.
This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.
