Several post-doc positions are available at the Integrated Optical Systems group of the University of Twente, associated to the MESA+ Institute for Nanotechnology. The post-doc will become part of a team working on the development of low-loss sputtered materials for Integrated Photonics. In particular, materials for fast modulation, electronic-photonics integration and integrated photonics devices operating in the ultraviolet and mid-infrared will be investigated.
