Doktorand*in Scalable Nonlinear Integrated Photonics

The Fraunhofer-Gesellschaft currently operates 76 institutes and research institutions in Germany and is one of the leading organisations for application-oriented research. Around 32 000 employees develop the annual research volume of 3.4 billion euros. Our PIC (Photonic Integrated Circuits) research group develops new photonic platforms and cooperates closely with the University of Duisburg-Essen (EBS, Integrated Photonics). We combine existing technologies with newly created (meta) materials and integrate our photonic circuits seamlessly with electronics. In this environment, we develop new materials that demonstrate excellent optoelectronic properties. The fields of application of our research are quantum photonics, artificial intelligence and sensor technology. Our use cases include the development of interferometric systems and neuromorphic photonics to enable data centers for AI with environmentally friendly low energy consumption in the future. The aim of the doctoral thesis is to research and test new photonic components which can be used in scalable quantum systems. Your work creates new technology modules that are faster, low-loss and more powerful. Efficient photonic systems require non-linear components that are to be demonstrated for the first time as part of your promotional work. The work is integrated into a core research topic of the group.

As part of your promotion, you will explore passive and active integrated optical components and circuits based on silicone photonics technology platforms (silicon nitride and aluminum nitride waveguides). First of all, look at the state of science and develop the theoretical foundations. Building on this, you simulate photonic components and first develop new components (e.g. modulators) based on new (meta) materials to maximize nonlinearity. After the concept phase, you develop new processes of process modules and combine them with existing technology. In cooperation with our process engineering team, plan and monitor the production in the in-house clean room and then characterize the resulting chips with ultra-modern measurement technology (high power laser, ultrashort pulse systems, wafer scale characterization of Silicon Photonics). You will publish the results of your work as scientific publications and present them at international conferences and in the project meetings with external partners. In addition, you will supervise student and scientific assistants as well as bachelor and master thesis.

Complete scientific studies (Master/Uni Diploma) in electrical engineering, physics, nanoengineering or comparable to very good grades Practical experience in the field of optics; preferably in Photonic Integrated Circuits (PIC), Silicon Photonics, Nanophotonics or Optoelectronics First practical experience in the field of nano and/or microtechnology preferably in the production of optoelectronic components or the simulation (preferably with lumerical) of photonic components Enthusiasm for experimental basic research with direct application reference Fun to create new things and form a dynamic research field Very good knowledge of English for cooperation in an international environment

Doctorate in an application-oriented topic within 3 years. You can access all the institute's own clean rooms and laboratories for your practical work. Teaching obligations will not be transferred to you. The doctoral degree is awarded by the University of Duisburg-Essen. In addition to the support provided by an institute-internal specialist, a regular organized exchange takes place on the scientific state of your work within the framework of a doctorate/paternal body. During the promotion period, you will be supported by accompanying offers. For example, you can benefit from regular doctoral student coaching and learn to safely apply professional methods of project management during your doctorate and to support the project acquisition. If the dissertation is submitted in due time, the option is to further deepen the research work within the framework of a connection agreement or to switch to other areas. The full-time post as a doctoral student with half-remuneration provides 50% of the time for your doctoral degree and 50% for cooperation in research projects as a scientific assistant. Flexible working hours (running time with integrated core working time from 9:30 to 15:00, Friday from 9:30 to 13:00) and mobile work on up to two days a week for better reconciliation of work and private life Occupational pension (VBL) and grant to the Deutschland-Ticket Job Very good transport with public transport/car and free parking and bicycle parking for employees Family and Occupational Compatibility Support: Mit-Kind-Office, Kindernotpflege und Beratungs zu Homecare-Eldercare etc. in cooperation with the pme family service Corporate Benefits: Benefits Offers from renowned manufacturers and brands JOBV1_EN
