Fraunhofer HHI has more than 30 years of experience in researching and developing a wide range of discrete and integrated photonic components and has a quality management system certified according to DIN EN ISO 9001. Fraunhofer HHI’s work includes the design of high-frequency photonic components (> 100 GHz) in InP for advanced optical networks, including lasers, modulators, and detectors. HHI has been offering foundry services for scientific and commercial customers since 2018.
In addition, hybrid photonic integrated circuits (PICs) based on PolyBoard, SiN, and TFLN single-mode waveguides in combination with active elements made of InP, GaAs, or GaN are being developed. Fraunhofer HHI has developed a diverse range of photonic components for telecom, datacom and sensing, such as high-speed lasers and photodetectors, and in many cases has brought them to application in close cooperation with industrial partners. In recent years, quantum technologies, including secure quantum communication and high-precision quantum sensing, have been established as a further focus of research.
