Building Scalable Silicon Microring Resonator‐Based Neuromorphic Photonic Circuits Using Post‐Fabrication Processing with Photochromic Material

Advanced Optical Materials, Volume 13, Issue 11, April 14, 2025.
One of the high‐impact research goals in neuromorphic photonics is to build scalable photonic artificial intelligence computing at high energy efficiency. This perspective paper discusses microring resonator (MRR)‐based large‐scale photonic neural networks, variations of MRR resonance wavelength from fabrication, and post‐fabrication processing with ...

Photochromic Molecules Enable Optical Control of Optomechanical Coupling in a Cavity

Advanced Optical Materials, Volume 13, Issue 10, April 4, 2025.
An optomechanical system with optically‐tunable coupling is introduced, featuring a multilayered membrane with a photochromic molecule and NIR‐absorbing dye. Laser cooling of a membrane vibrational mode is evidenced, with a 60% improvement in efficiency achieved upon photoisomerization, as well as reversible control of photothermal forces.

Emerging 2D Material‐Based Synaptic Devices: Principles, Mechanisms, Improvements, and Applications

SmartMat, Volume 6, Issue 2, April 2025.
Two‐dimensional (2D) materials and their heterojunctions have emerged as a nanoscale hardware development platform for synaptic devices due to their intrinsic high surface‐to‐volume ratios and sensitivity to charge transfer at interfaces. Here, the latest progress of 2D material‐based artificial synapses is reviewed regarding biomimetic principles ...
