Description

The Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) is one of the 59 institutes of the Fraunhofer Gesellschaft in Germany. The work of all these institutes is devoted to applied research, mainly for the interest of industrial partners. Only a small part of the total budget of these institutes is funded by the government. The main income is realized on contract-based work within public funds and industrial companies. The IOF has 109 employees and a budget of 9M€.
The Micro-optics group of IOF has more than 10 years experience in design and fabrication of microoptical and integrated optical elements up to the module level. Starting point for projects is in most cases a detailed optical design and analysis of the complete system to be realized. A huge number of different design tools are available at IOF, including ray-tracing and wave optical design methods, stray light analysis tools, rigorous calculation techniques, and BPM methods for waveguide design.
Within former projects competencies have been built up concerning the fabrication of micro-optical components, such as wafer scale reflow and replication (casting and curing, hot embossing, injection molding) for microlenses, laser direct writing of diffractive elements, fabrication of single- and multimode waveguides, prisms and waveguide coupling gratings in polymers (e.g., EU-project BriteEuram BE 5072). The technological equipment for replication tool original fabrication is available (PE-CVD, RIE and RIBE, mask-aligner spin-coating in clean room) as well as the design tools (Ray-Tracing, Wave-Optics Design, FEM, BPM) and measurement set-up’s for the characterization of optical properties of (micro-) optical elements and materials.
