# Silicon Photonics Integrated Circuits

Canada's photonics research community, centered in Ottawa and Waterloo, is developing silicon photonic chips for AI data centers, telecommunications, and quantum networking — leveraging the legacy of Nortel and JDS Uniphase.
- Technology Readiness Level: 6/9
- Impact: 4/5
- Investment: 4/5
Canada has a deep legacy in photonics — the science and technology of light — dating back to Nortel, JDS Uniphase, and the Ottawa-Waterloo photonics corridor. Today, Canadian companies and universities are developing silicon photonic integrated circuits that combine optical and electronic functions on a single chip. Applications include AI data center interconnects (where photonics dramatically reduces power consumption compared to electrical connections), 5G/6G telecommunications, LiDAR for autonomous vehicles, and quantum networking.

Silicon photonics matters because the exponential growth of AI workloads is creating a data movement bottleneck — moving data between chips consumes more energy than the computation itself. Photonic interconnects can move data at the speed of light with a fraction of the energy cost of electrical connections. As AI data centers scale to consume gigawatts of power, photonic solutions become essential rather than optional.

Canada's strategic position in photonics is built on decades of accumulated expertise and a workforce that survived the Nortel collapse. The connection to quantum computing is not coincidental — Xanadu's photonic quantum computers and Photonic Inc.'s silicon-photonic quantum processors both build on the same fundamental technology base. This convergence of classical photonics, quantum photonics, and AI creates a uniquely Canadian technology cluster with applications spanning multiple market categories.
