E-PhoQuant research group

The Thuringian Innovation Center InQuoSens intends to strategically strengthen its position in the research and innovation field of quantum technologies with the research group E-PhoQuant. The application of quantum physical phenomena will revolutionize information transmission and processing with regard to data security. Within the scope of the research, a heterogeneous integration solution for the realization of compact quantum optical devices and modules will be developed. Based on a novel composite substrate, a system-in-package platform will be created to realize highly integrated combined microelectronic/optical systems. This system approach is not only aimed at miniaturization, but also builds on wafer-level structuring technologies, which is a prerequisite for a future transfer to industry. To this end, the following focal points are to be addressed in particular:

  • Technological realization of optical surface quality and high-precision electrical contacting structures on composite substrates,
  • Surface and volume functionalization of the optical layer by means of plasma- and UKP-laser-based processing
  • Design and integration of quantum optical functional structures in composite substrates
  • System integration of electronic components

To solve the tasks, an interdisciplinary approach is pursued in the research group, which is also reflected in the composition.
