Research Engineer in Development of Thin-Film-Based Waveguides
Job description
As a Research Engineer, you will play a central role in the development of a new platform based on ferroelectric thin\-film crystals for applications in nonlinear optics and quantum photonics. The work is carried out in close collaboration with researchers, PhD students, and external partners.
Your main responsibilities will include:
- Development of processes for the fabrication of ferroelectric thin\-film crystals, including wafer bonding, thin\-film slicing, and polishing
- Planning, execution, and optimization of micro\- and nanofabrication processes in a cleanroom environment
- Fabrication of waveguide structures, for example through ion exchange, etching, and laser\-based micromachining
- Modelling and numerical simulation of waveguide structures, including mode analysis, propagation properties, and optimization of geometries for specific functionalities
- Characterization of materials and devices, including optical measurements (e.g., SPDC and squeezing)
- Documentation of processes and results, and contribution to scientific publications and technical reports
Qualifications
Requirements
- A graduate degree or an advanced level (higher education) in the research subject or equivalent competence.
- Master’s degree in physics or a closely related field
- Demonstrated hands\-on experience with experimental work in a laboratory environment· Solid foundation in optics, photonics, and quantum optics
- Strong ability to document work clearly and communicate effectively in both spoken and written English as we work in an international environment.
- Hands\-on experience with optical characterization techniques (e.g., SHG, SPDC, or waveguide measurements)
- Experience with numerical modeling and simulation of optical systems
- Programming skills (e.g., Python, MATLAB) for data analysis and experimental control
- Awareness of diversity and equal opportunity issues, with specific focus on gender equality
- Collaborative abilities
- Independence
