A Complete
Co‑Packaged Optics Solution
Ayar Labs delivers the most performant, compatible, and manufacturing-ready co-packaged optics (CPO) solution for AI scale-up. Combining the TeraPHY™ optical engine and SuperNova™ external light source, our CPO solution creates optical fabrics that enable thousands of GPUs to operate as a single unified system with the bandwidth and latency needed for hyperscale AI infrastructure.
TeraPHY™ Optical Engine
World’s First Optical Engine Purpose-Built for AI Scale-Up
As AI models and GPU clusters grow, copper interconnects are becoming a critical bottleneck. TeraPHY™ replaces copper with optical connectivity that delivers the bandwidth, performance, power efficiency, and low latency needed to connect large GPU clusters across racks and data centers.
Built on proven silicon photonics and standard CMOS manufacturing, TeraPHY™ integrates with system-in-package architectures and is powered by SuperNova™ or other compatible external light sources.
Key Features
- Industry-leading microring modulator (MRM) technology
- Compatible with multiple detachable fiber connectors for reliable and serviceable deployments
- Silicon photonics on a robust high-volume manufacturing CMOS process
- Extends GPU-to-GPU connectivity across tens of meters, with reach up to 2 km
- Flexible light source integration with Ayar Labs’ SuperNova™ or other compatible external light sources
- DWDM optical engines are compatible with the OCI-MSA standard

SuperNova™ Light Source
Purpose-Built to Power TeraPHY™ Optical Engines
SuperNova™ is Ayar Labs’ external light source, purpose-built to power TeraPHY™ optical engines in AI scale-up deployments. By disaggregating the laser from the optical engine, SuperNova™ enables improved thermal efficiency, reliability, and serviceability for co-packaged optical deployments.
Its compact, low-power design in the industry-standard ELSFP form factor pairs seamlessly with TeraPHY to deliver a complete, manufacturing-ready optical solution for AI scale-up.
Key Features
- High-power, multi-wavelength architecture
- Up to 23 dBm per wavelength
- Enterprise-grade reliability, availability, and serviceability (RAS) for mission‑critical deployments
- Industry-standard external laser small form factor pluggable (ELSFP) for scalable, field-replaceable deployment
- Liquid cooling compatible
- DWDM lightsource is compatible with OCI-MSA standard
