Spatiotemporal all-optical diffractive neural networks empowered by spatiotemporal light field manipulation

All-optical neural networks (AONNs) offer significant potential for feature detection and pattern recognition by leveraging light-speed processing, high parallelism, and low energy consumption. However, traditional AONNs are limited to spatial light intensity distributions for bo...

Erasable PCM-Assisted Probe for In Situ Monitoringof Photonic Integrated Circuits

Abstract Photonic integrated circuits (PICs) are essential for modern optoelectronics, yet fabrication-induced random phase errors often necessitate precise detection and calibration before application. Optical probing offers a direct detection method before packaging. However, c...
