Computing at the Speed of Light: Where Optical Computing Stands in 2026
Copper wires have become the bottleneck of the AI era, limiting speed and turning data-centre power into heat. Optical computing, which processes information with light instead of electricity, is moving from the lab into real infrastructure. This article explains what it is, where it is already in use, the 2026 breakthroughs pushing it forward, and why its biggest near-term impact will be cheaper, faster and greener AI from the cloud.
