Products & Services

Fraunhofer HHI researches optochips and Photonic Integrated Circuits (PICs) for 100+ Gbit/sec data transmission and detection and sensor applications. The scientists offer production and development services in all of their activities to the German and international industry. As an example, if you already have a concrete optochip design in mind, the researchers offer additional consulting and would do design and fabrication iterations. Or if you start with a target spec, they would typically begin with a feasibility study and generate a design of their own. In all cases, they are able and willing to do initial production volumes in ISO certified, qualified production. Furthermore they offer e-beam services, and design-to-spec diffractive optical elements.
High-Speed Photodetector Modules

Components for 1Tb/s Transmission and Microwave Photonics.
Fraunhofer HHI provides single and balanced photodetector modules with a bandwidth up to 145 GHz operating from the O- to the L-band. The intended application for the modules is test and measurement. For the application of microwave photonics dedicated high-power photodetector modules are presented.

News & Innovations

Lidar sensing, beam steering & combining
We present a 2-dimensional optical phased array (OPA) realized with a 3-dimensional PolyBoard chip. Beam steering was demonstrated with an initial 2x4 array. Without any front lens, the maximum steering angle is about 10°. This technology can scale up to 32x256 arrays. The OPA module is coupled to a standard single-mode fiber and a ribbon cable for beam control. Further reading
