OpenLight

OpenLight Photonics is pioneering silicon photonics with the world’s first open PDK, enabling heterogeneous integration of III-V devices, including lasers, optical amplifiers, high-speed electro-absorption modulators (EAMs), and high-efficiency photodetectors. Available through Tower Semiconductor’s PH18DA process, the platform combines these active components with a comprehensive library of silicon and silicon nitride photonic building blocks, including waveguides, edge and grating couplers, and more complex structures such as filters, switches, and splitters—enabling customers to design a wide range of photonic ASICs (PASICs). OpenLight offers a library of reference designs for standardized datacom applications, significantly shortening time-to-market by providing verified designs. In addition, OpenLight provides design, layout, test and fabrication services for custom circuits and components leveraging its experience and partner ecosystem to help transform bare dies into finished products.
