The Window of Light: Why Silicon Photonics Is Becoming Strategic Infrastructure for AI and Quantum

From data‑centre optics to quantum sensing, silicon photonics is slowly becoming the backbone of national AI and semiconductor strategies, with the UK poised to become a global beachhead.

Silicon photonics now sits at the intersection of three powerful currents:

semiconductor manufacturing,

AI hardware, and

quantum sensing and communications.

In 2026, those currents are converging into a global infrastructure story about whether regions like the US, Europe, and the UK can build, own, and scale the fabs, pilot lines, and talent needed to …
