Research associate in the field of micro- & nanostructured optics (IOF-2022-64)

The Fraunhofer-Gesellschaft ( currently operates 76 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 30 000 employees work with an annual research budget of 2.9 billion euros. 

Fraunhofer is the largest organization for application-oriented research in Europe. Our research fields are geared to people's needs: Health, Safety, Communication, Mobility, Energy and Environment. We are creative, we shape technology, we design products, we improve processes, we open up new paths.


The research group “Center for Advanced Micro- and Nano-Optics” (CMN-Optics) deals with the design, fabrication, and characterization of sophisticated diffractive optical elements. The core technology used is electron beam-lithography, with which structures are exposed with nanometer precision into a resist mask and transferred to a substrate by subsequent etching processes. The diffraction gratings, holograms, and beamformers manufactured in this way are used in space, astronomy, and laser industry.

To support the research group, we are looking for a research associate to design and develop manufacturing technology for integrated optical components to be used in photonic quantum applications.


What you will do

Within the RAINBOW project, the technology for the realization of complex photonic integrated circuits (PICs) based on lithium niobate-on-insulator (LNoI) substrates will be further developed. In particular, you will perform the following tasks:

  • Design of integrated optical elements according to application-specific requirements, especially of waveguide components based on LNoI
  • Further development of existing lithographic manufacturing processes with a focus on minimizing manufacturing-related waveguide losses
  • Development and adaptation of manufacturing technology for electrical control of integrated optical functions (amplitude/phase modulation)
  • Collaboration with other research groups at the Center of Excellence in Photonics in the field of integrated-optical component development
  • Publication and presentation of research results in peer-reviewed journals and at conferences
  • Planning, coordinating, and executing projects from a technical, scheduling, and contractual point of view
  • Acquisition and management of customer projects


What you bring to the table

  • You have successfully completed your university degree, preferably with a PhD, in the field of physics, optics, engineering, or a comparable field. 
  • You have experience and expertise in the field of micro- and nanostructure technology, preferably in electron beam-lithography. 
  • Ideally, you have already gained first experiences in modeling and characterization of integrated optical devices as well as in (high frequency) electronics. 
  • You have a high technical understanding as well as strong analytical skills. 
  • Excellent communication and teamwork skills as well as an independent, pro-active, creative, and diligent way of working characterize you. 
  • As Fraunhofer IOF works on an international level in many ways, we require a good command of written and spoken German and English.


What you can expect

  • Independent work as well as personal and professional development opportunities in challenging and practical R&D projects
  • Networking with first-class industry partners
  • Modern-equipped working environment 
  • Flexible working hours and a family-friendly workplace


The weekly working time is 39 hours. The position can also be filled on a part-time basis. The position is initially limited to 2 years with possibility of prolongation. Appointment, remuneration and social security benefits based on the public-sector collective wage agreement (TVöD).


We value and promote the diversity of our employees' skills and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity. Severely disabled persons are given preference in the event of equal suitability. 


With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
