LightOn Optical Processing Unit : Scaling-up AI and HPC with a Non von Neumann co-processor

2021

Beyond pure Von Neumann processing Scalability of AI / HPC models is limited by the Von Neumann bottleneck for accessing massive amounts of memory, driving up power consumption.

Streamlined optical training of large-scale modern deep learning architectures with direct feedback alignment

2026 · Proceedings of the National Academy of Sciences

Modern deep learning relies nearly exclusively on dedicated electronic hardware accelerators. Photonic approaches, with low consumption and high operation speed, are increasingly considered for inference but, to date, remain mostly limited to relatively basic tasks. …
