MIT's All-Optical AI Chip Achieves 58x Speedup
2025-01-15
Researchers at MIT have developed an all-optical AI chip that processes information directly using photons, bypassing the digitization step for a massive speed boost. Achieving a latency of 410 picoseconds, it's 58 times faster than a standard CPU. This breakthrough involves implementing a complete deep neural network on a photonic chip, including both linear matrix operations and non-linear thresholding functions – a challenge previously faced by photonic computing. While currently limited in parameter count, this technology promises applications in low-latency fields like autonomous driving and advanced automotive vision systems.
