Research Engineer in Development of Thin-Film-Based Waveguides Full-time

Research Engineer in Development of Thin-Film-Based Waveguides

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

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
• 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.

Preferred qualifications

• 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

Great emphasis will be placed on personal skills.
