Reservoir Computing with All‐Optical Non‐Fading Memory in a Self‐Pulsing Microresonator Network

open access: yesAdvanced Optical Materials, Volume 13, Issue 11, April 14, 2025.
A photonic reservoir computing architecture based on 64 coupled silicon microring resonators is used to achieve non‐fading memory, demonstrating robust multi‐timescale signal processing capabilities. The passive photonic network exhibits nonlinear dynamics and multistability, facilitating extended information retention exceeding tens of microseconds ...

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Anisotropic Laser Performance in an Optically Isotropic Crystal by Phonon Engineering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
The symmetry‐breaking in a photon–phonon collaboratively pumped laser is investigated for the first time. Using an optically isotropic Nd:YAG crystal, the phonon‐assisted electronic transitions accompanied by anisotropic fluorescence emission are observed.

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...
