OpenLight is a leader in custom Photonic Application-Specific Integrated Circuit (PASIC) design and manufacturing. The company specializes in integrated silicon photonics technology, combining active and passive optical components into a single chip. Founded in 2022 as a joint venture between Synopsys and Juniper Networks, OpenLight became an independent company in 2025 after securing $34 million in Series A funding. It is headquartered in Santa Barbara, California, with additional offices in Silicon Valley. OpenLight offers design enablement, in-house design services, and production of PASICs through partner foundries. Their Process Design Kit (PDK) allows customers to design their own PASICs, ensuring production-ready designs from the start. The technology serves various high-growth markets, including data centers, telecommunications, automotive, and healthcare. OpenLight operates an open foundry model, licensing its technology to semiconductor foundries globally, and aims to democratize PASIC design for a wide range of applications.
