How Optical I/O is Enabling the Future of Generative AI: A Q&A with Ayar Labs CTO Vladimir Stojanovic


Driving the AI Revolution

with Optical I/O

Ayar Labs is transforming AI infrastructure by accelerating data movement. Our breakthrough optical I/O solution enables composable system architectures optimized for large-scale AI workloads, while also scaling performance and throughput for training and inference. Standards-based and commercial-ready, Ayar Labs’ industry-first technology shatters data bottlenecks and gives customers the bandwidth, energy efficiency, and latency that AI workloads require.

“Optical connectivity will be important to scale accelerated computing clusters to meet the fast-growing demands of AI and HPC workloads. Ayar Labs has unique optical I/O technology that meets the needs of scaling next-generation silicon photonics-based architectures for AI.”

Bill Dally,
Chief Scientist & Senior VP of Research, NVIDIA

Solving Data Bottlenecks with Optical I/O

The soaring complexity and size of AI models are overwhelming infrastructure that is based on traditional interconnect technology.  By moving data using light, optical I/O makes it possible to continue scaling computing system performance, enabling the next system design breakthroughs for the growth of generative AI, disaggregated data centers, and more.

Moving Data with Light

Moving Data with Light

Ayar Lab’s solution combines two industry-first technologies — the TeraPHY™ optical I/O chiplet and SuperNova™ multi-wavelength remote light source — to maximize compute efficiency while reducing costs, latency, and power consumption. It is standards-based, future-proof, and scalable, designed to optimize AI performance.

Based on open standards and optimized for both AI training and inference, Ayar Labs’ optical I/O solution is backed by a robust ecosystem that enables it to integrate smoothly into AI systems at scale.
