Space based quantum optics experiments face harsh operating conditions in terms of thermal and mechanical fluctuations, while giving strong limitations to payload mass and volume.
We developed miniaturized optical bench systems based on Zerodur glass ceramics allowing for laser beam manipulation, beam switching and frequency stabilization in extreme environments. Suitability of these optical systems has been demonstrated in the successful sounding rocket missions FOKUS, KALEXUS and MAIUS.
On this poster, we present elaborated developments of optical technologies, comprised of optical benches with free-space optics combined with fiber components. Furthermore, we report on current investigations of Zerodur based vacuum systems, providing a miniaturized and mechanically stable vacuum technology, while paving the way to a fully integrated quantum optical system.
