OpenLight has raised $50 million in Series A-1 financing to support the global rollout of its next-generation silicon photonics platform, bringing the company’s total funding to $84 million. The Santa Clara-based company said the oversubscribed round reflects rising demand for advanced photonic integrated circuits across AI data centers, telecommunications, sensing, medical technology and quantum computing. The announcement reinforces OpenLight’s position in the fast-expanding photonics market, where bandwidth, power efficiency and scalable manufacturing are becoming critical priorities.


Strong Investor Backing

The latest funding round was led by Matter Venture Partners, with new participation from Acclimate Ventures and Catapult Ventures. Existing backers Xora Innovation, Capricorn Investment Group, Mayfield and New Legacy also joined the round, signaling continued confidence in OpenLight’s commercial strategy and technology roadmap. Matter Venture Partners said optical technology will be central to the future growth of AI infrastructure and data centers, particularly as global demand for high-speed connectivity continues to increase.

Scaling a Photonics Platform

OpenLight’s platform is built around heterogeneous integration, combining indium phosphide with silicon photonics to enable active and passive optical components on a single chip. Its process design kit, validated through Tower Semiconductor’s photonics foundry, gives customers access to production-ready components such as integrated lasers, modulators, optical amplifiers and detectors. By providing these core building blocks, OpenLight aims to help companies develop custom Photonic Application-Specific Integrated Circuits more efficiently and reduce the time required to move from design to manufacturing.

Customer Adoption and Intellectual Property

The company said more than 25 customers are currently using its PDK to design and fabricate production-grade PASICs for applications spanning AI infrastructure, telecom networks, automotive sensing, industrial systems and quantum computing. OpenLight also holds more than 410 patents covering its PDK and the manufacturing processes behind heterogeneously integrated III-V photonics. This intellectual property base gives the company a strong technical foundation as it seeks to expand commercial adoption and support customers developing highly specialized optical chips.

Product Roadmap and Market Outlook

OpenLight plans to use the new capital to broaden its library of active and passive photonics components, including 400G modulators and indium phosphide-based on-chip laser technology. The company will also accelerate work on standards-based reference photonic integrated circuits at 1.6T and 3.2T, which are expected to support higher-performance optical connectivity for future data center and communications systems. President and CEO Adam Carter said the funding will help OpenLight expand worldwide sales and technical support while advancing its roadmap for large-scale deployment of heterogeneous photonic integrated circuits.


The financing comes as optical connectivity becomes increasingly important for AI computing, cloud infrastructure and other data-intensive technologies. By combining foundry-validated design tools, integrated active photonics and a growing customer base, OpenLight is positioning itself as a key supplier of enabling technology for next-generation optical systems. With fresh investor support and an expanded development roadmap, the company is set to push its PASIC platform into broader global markets.
