Now on #NaturePhotonics: a fully integrated optical neural network on a single chip: https://lnkd.in/dM-WCsa6 As deep neural networks continue to transform industries, the limitations of traditional CMOS electronics, particularly in energy consumption and throughput, are becoming more apparent. Saumil Bandyopadhyay et. al tackle this challenge head-on by leveraging photonic integrated circuits to achieve unprecedented performance in optical processing. In this work, they use a scalable photonic integrated circuit integrating coherent optical processors for both *matrix algebra* and *nonlinear activation* functions. They demonstrate a deep neural network processing (6 neurons, 3 layers) with a latency of just 410 ps, utilizeing processing at the speed of light. Morover, they implement backpropagation-free training with 92.5% accuracy on a six-class vowel classification task—comparable to digital systems but orders of magnitude faster. This work opens new pathways for ultrafast optical computing in real-time applications, from high-speed communications to advanced sensing and AI.

Very cool…
Finally!
Amazing!
What an art ! Good Job Dr Saumil Bandyopadhyay
Impressive paper👏 and truly inspiring. Have you ever thought about the potential benefits of packaging the chip using flip-chipping instead of wire bonding? ➕This could enhance thermal management, improve alignment precision, and reduce the overall footprint. We would love to discuss this further with you! 🤝
