At ECOC24, Sivers Semiconductors and Ayar Labs will jointly demonstrate the integration of Sivers’ 16-wavelength distributed feedback (DFB) laser array into Ayar Labs’ SuperNova multi-wavelength light source, delivering 16 Tbps of bi-directional bandwidth. The demonstration showcases a CW-WDM MSA compliant 16-wavelength light source.
The companies state that by integrating optical I/O directly into GPU or accelerator packages, this technology enables faster, more efficient communication within GPU clusters, delivering 5-10x faster speeds while reducing power consumption. The solution optimizes infrastructure for handling complex AI workloads and allows scalable, high-performance AI fabric designs.
Andrew McKee, Managing Director of Sivers Semiconductors’ Photonics business unit, highlighted the impact of their collaboration. “We are proud to demonstrate the latest SuperNova™ light source module incorporating Sivers Semiconductors’ 16-lambda WDM Laser Array. We continue to drive performance improvements with increased output powers and higher wavelength count.” Vladimir Stojanovic, CTO of Ayar Labs, added, “Our innovative optical solution enables AI scale-up fabrics with unprecedented power, performance, and efficiency, boosting the economics of rapidly evolving AI workloads.”
