1. Performance per Watt: Photon vs. Electron Efficiency One of the biggest promises of photonic AI accelerators is superior energy efficiency. By using light to perform computations (especially matrix multiplications at the heart of AI models), photonic chips can potentially execute more operations per joule than electronic GPUs: Bottom Line: On raw efficiency, photonic accelerators…

A global research team led by Japan’s NICT demonstrated 1.02 Pb/s transmission over 1,808 km using a 19-core fiber and custom optical amplifiers. NICT, ASTRODESIGN, and Fujikura deployed a multi-core fiber system with eight 4-core fibers (32 cores total) enabling uncompressed 8K video across a 300 m link at about 70 Gbps per stream. In…
