Ayar Labs

Type: Company (Optical I/O Chiplets)

Ayar Labs has unveiled the world's first optical chiplet compliant with the Universal Chiplet Interconnect Express (UCIe) standard, enabling optical I/O to be integrated directly into multi-die chip packages alongside compute chiplets. Nvidia's strategic backing signals that the dominant AI hardware company sees optical interconnect as essential for next-generation AI systems.

SuperNova Light Source

• 16 wavelengths — wavelength-division multiplexing (WDM) for maximum bandwidth density
• 8 Tbps aggregate bandwidth — per chiplet
• UCIe compliant — industry standard for chiplet-to-chiplet interconnect
• Co-packaging ready — designed for integration with compute dies (GPUs, AI accelerators)

TSMC COUPE Partnership

• COUPE: TSMC's Compact Universal Photonic Engine platform
• Integration: Enables optical chiplets to be co-packaged with TSMC-fabricated compute dies
• Ecosystem: Makes optical I/O accessible to any chip designer using TSMC
• Manufacturing: Leverages CoWoS and InFO advanced packaging

Funding & Commercialization

• $500M raise: March 2026 funding round
• Nvidia backing: Strategic investment from dominant AI chip company
• Production samples: Targeted for 2026
• Data center deployment: On track for 2027-2028
