Ayar Labs raises $25M more

SANTA CLARA, Calif. – Ayar Labs, a leader in silicon photonics for chip-to-chip connectivity, today announced it has raised an additional $25 million in Series C1 funding, bringing its total Series C raise to $155 million. The oversubscribed up round was led by new investor Capital TEN. VentureTech Alliance also entered the Series C expansion that included participation by previous investors Boardman Bay Capital Management, IAG Capital Partners, NVIDIA and Tyche Partners. Existing strategic and financial investors include Applied Ventures, GlobalFoundries, Hewlett Packard Pathfinder, Intel Capital and Lockheed Martin Ventures.

"We believe that future computing solutions will include large-scale use of silicon photonics for data communications, and have been following Ayar Labs for some time now," said Pin-Nan Tseng, General Partner at Capital TEN. "Given our deep expertise in the semiconductor industry and the Taiwan semiconductor ecosystem, we believe Ayar Labs has the technology solution, people, capital, and broad support to lead in the transition from copper to optical interconnects for scale-out computing and memory applications."

Ayar Labs' patented optical I/O approach uses industry-standard, cost-effective silicon processing techniques to replace traditional electrical I/O with fast, high-density, low power optical I/O chiplets and multi-wavelength light sources. Moving data between chips using light instead of electricity breaks the performance, power and distance limitations of copper interconnect, critical for latency-sensitive applications such as high performance computing, AI and machine learning. Optical I/O will also impact other areas that require rapid transfer of data, such as cloud and data center, telecommunications, and aerospace and defense.

Ayar Labs will use the funds to accelerate the implementation and commercialization of its optical I/O solutions to address the power consumption, latency, reach and system bandwidth bottlenecks that threaten future advances in generative AI, while also expanding the company's product offerings and development efforts.
