GlobalFoundries bets AI infrastructure's real bottleneck is copper wiring, not compute power, launching silicon photonics platform SCALE in May 2026

GlobalFoundries announced SCALE (Silicon photonics Co-packaged Advanced Light Engine solution) in May 2026, the industry's first platform to meet Optical Compute Interconnect Multi-Source Agreement specifications for AI scale-up architectures, demonstrating 8λ and 16λ bi-directional DWDM natively on its platform.

Instead of adding more GPU clusters and electricity like Amazon, Alphabet, Microsoft, and Meta Platforms, GlobalFoundries is replacing copper wiring with optical transceivers (components that transmit data through light rather than electricity) placed directly alongside chips, reducing heat generation, signal loss, and power consumption in AI data centers.

The company acquired Advanced Micro Foundry in Singapore in November 2025 to add manufacturing capacity, intellectual property, and engineering depth for silicon photonics production at the scale required by hyperscalers; silicon photonics revenue is expected to nearly double again in 2026, with over 500 design wins logged in 2025.

The U.S. government is backing GlobalFoundries with a proposed $375 million award to help build out domestic quantum manufacturing infrastructure.
