Its TeraPHY optical engine, powered by the SuperNova external light source, creates the optical fabrics that connect thousands of GPUs across racks, and Ayar Labs is now valued at $3.8 billion as it replaces the copper wiring in semiconductors with fiber optics.
The company's founders published results in Nature demonstrating the world's first processor to communicate using light, and Ayar Labs has since drawn strategic investment from AMD, Intel, MediaTek, and NVIDIA.
