In the latest EE Times podcast "AI With Sally," our Founder and CEO Nick Harris spoke with Sally Ward-Foxton about photonics in the data center.

In the episode, Harris explains why AI has shifted from a compute-bound problem to an interconnect- and memory-bound one, how Lightmatter evolved from pursuing photonic processors to building optical networking technology, and why the company's new integrated laser platform represents the next step toward scaling AI infrastructure beyond what copper can support.

Co-packaged optics is becoming a critical conversation in AI infrastructure — and it will take a full ecosystem to move it forward.

At @LightmatterCo InterConnect 2026 ecosystem and media event, I joined Nicholas Harris, Simona J., Ritesh Jain and Bob Turner to discuss the market, key challenges and the roadmap for CPO.

Great discussion and an important moment for the industry.
