Researcher, Photonics Integration

VTT Technical Research Center

We are looking for an ambitious and results-oriented researcher with a strong background in semiconductor physics, electronics and photonics. As a researcher at VTT, you will have a key role in the development of new integrated photonics technologies over a wide spectral range, from UV to far IR and beyond. You identify and solve problems independently and creatively, while working closely and flexibly with a team of experts. You focus on the design and fabrication aspects of the process, especially in terms of new active materials and their integration, and participate in the characterization. You understand the big picture and provide input in the concept development.
In this position, you have the opportunity to develop new active photonic devices based on 2D materials and their integration to the microelectronics process flow in close collaboration with international photonics and semiconductor foundries. Your work will have a connection to large European research initiatives Graphene Flagship and Quantum Flagship where VTT has a strong role, and will be based on intense collaboration with VTT’s core technologies in silicon photonics. The applications will also link with our core technologies in bio diagnostics, telecommunications beyond 5G and quantum computing.
With us, you will be responsible for:
– Development of 2D materials based active photonic components together with our experts in 2D materials and integrated photonics
– Component design, fabrication and process integration in our extensive cleanroom
– Wafer-scale 2D materials integration technology development for photonic applications, together with our international collaborators
– Identifying and solving the key issues within your domain of expertise
– Communicating and solving those issues in tight collaboration with others at VTT
– Communicating and solving problems with external partners
We expect you to have:
We are looking for a person with experience in semiconductor physics, integrated photonics and process integration, and a master’s or PhD level degree in physics, photonics, materials science or electrical engineering, or other field connected closely to active photonic devices. Your background and interests are primarily in the experimental work, although numerical modeling and practical programming skills are certainly welcome. You are proficient in English.
Ideally, your background includes the following:
– Master’s degree or Ph.D. in experimental physics, photonics, materials science, or a related field
– At least 2 years of experience in research on integrated photonics, in particular high speed devices (e.g. detectors, modulators), with focus on device physics and process integration
– At least basic programming, photonics device simulation and electro-optical characterization skills
As a person, you strive for excellent results but also prioritize and make pragmatic choices. You are focused and systematic. You contribute to a positive team spirit and prioritize the needs of the team. You are hard working but you also communicate, collaborate, and delegate effectively. You are eager to work with new topics with open-minded and curious attitude. You are able to bring clarity over complexity and identify the essential bottlenecks. In addition, you have the ability and patience to tolerate uncertainty and unexpected outcomes.
