ECOC Conference – Sivers Semiconductors, Ayar Labs Optical Solution For AI scale-up Fabrics

Sivers Semiconductors and Ayar Labs will hold a joint live demonstration, showing the Sivers Semiconductors 16-wavelength distributed feedback (DFB) laser array integrated into the Ayar Labs SuperNova^™ multi-wavelength light source for 16 Tbps of bi-directional bandwidth – a level of bandwidth essential for AI scale-up networks.

The first 16-wavelength light source in the industry that is compliant with CW-WDM MSA will be unveiled by Sivers Semiconductors and Ayar Lab at the next European Conference on Optical Communication (ECOC) Conference in Frankfurt, Germany, September 23–25, 2024.

Together with Ayar Labs, Sivers Semiconductors will present a live demonstration of our 16-wavelength distributed feedback (DFB) laser array integrated into the SuperNova light source from Ayar Labs. During the show, the demonstration will be at our booth, #C106. Throughout the event, representatives from Ayar Labs and Sivers Semiconductors will be on hand to walk guests through the live demonstration.

This state-of-the-art combined technology is propelling revolutionary developments in AI applications. Foundational AI models require more GPU/accelerator processing power and memory as they get bigger and more complicated.

This approach allows communication across the GPU cluster and ensures scalable and efficient infrastructure to handle the growing demands of AI workloads by incorporating optical I/O directly within the GPU or accelerator package.

Optical connections optimize GPU utilization and accelerate AI performance by delivering 5–10x faster communication speeds inside the cluster, all while drastically reducing power consumption.

Andrew McKee, Managing Director of Sivers Semiconductors’ Photonics business unit, added: “We are proud to demonstrate the latest SuperNova^™ light source module incorporating Sivers Semiconductors 16-lambda WDM Laser Array. We continue to deliver industry leading Laser Arrays from our InP100 platform driving performance improvements through increased output powers and higher wavelength count.”

“Sivers Semiconductors has been a key partner in our journey to bring high-bandwidth, low-latency optical I/O to market at scale. This demonstration of our second-generation SuperNova light source, combined with Sivers’ 16-wavelength laser array, highlights the significant progress we’ve made together,” said Vladimir Stojanovic, CTO of Ayar Labs. “With AI models continuing to grow in size and complexity, our innovative optical solution enables AI scale-up fabrics with unprecedented power, performance, and efficiency, boosting the economics of rapidly evolving AI workloads.”
