Overview

  • Lightmatter and Lightelligence have unveiled photonic chips capable of performing AI tasks like matrix multiplication and running deep learning models with high precision.
  • These chips leverage light instead of electricity, offering significant improvements in speed and energy efficiency over traditional electronic processors.
  • The technology addresses limitations of Moore's Law and can be manufactured using existing semiconductor facilities, enabling scalability.
  • Demonstrations include solving optimization problems, playing Atari games, and executing AI models like BERT with performance comparable to conventional chips.
  • While prototypes are nearing practical applications, experts estimate that mainstream adoption of photonic computing may take up to a decade.
