OpenLight makes it easier for engineers and companies to build high-performance photonic chips by providing a modular silicon photonics platform and related services. The company designs and manufactures Photonic Application-Specific Integrated Circuits (PASICs) that integrate active and passive components—lasers, modulators, amplifiers, and detectors—on a single silicon photonics die, and it supplies a Process Design Kit (PDK), in-house design/build services, and production via licensed foundry partners. OpenLight operates an open foundry/licensing model and offers PASIC design enablement tools (PDK), manufacturing services, and SaaS-like design workflows for semiconductor and photonics design teams. Its technology targets datacom, telecom, LiDAR, healthcare, HPC, AI, and optical computing markets where low-power, high-speed photonic integration is required.
