Ayar Labs: Silicon Photonics Leader Secures $25 Million In Funding

By Dan Anderson • Jun 11, 2023

Ayar Labs – a leader in silicon photonics for chip-to-chip connectivity – announced recently it has raised an additional $25 million in Series C1 funding, bringing its total Series C fundraising to $155 million. This oversubscribed up round was led by new investor Capital TEN. And 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.

The company’s patented optical I/O approach utilizes industry-standard and 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. And 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 like cloud and data center, telecommunications, and aerospace and defense.

Ayar Labs plans to use the funding 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. NVIDIA – which participated in Ayar Labs’ earlier Series C raise in April 2022 – increased its investment in the company.

Recently named one of America’s Best Startup Employers by Forbes, the funds will also help the company increase hiring plans by up to 50% this year. And Ayar Labs has received a number of other accolades in recent months. Mark Wade, Ayar Labs’ Co-Founder, CTO and Senior Vice President of Engineering, was recently appointed to Global Semiconductor Alliance’s CTO Council. And Wade was also recently named to Electro Optics’ inaugural “The Photonics 100 2023” list.
