Ready to turn quantum-engineered materials into scalable photonic devices?

At imec, we develop advanced integrated-photonics technologies for next-generation optical interconnects, computing, communications and sensing.

We are looking for an R&D Engineer to strengthen our work on waveguide-integrated III-V active photonic devices.

Your primary focus will be the simulation-driven design and experimental validation of III-V modulators integrated with silicon-photonics platforms, particularly quantum-confined Stark effect (QCSE) electro-absorption modulators based on multi-quantum-well heterostructures.

Depending on project needs and your expertise, you may also contribute to MOSCAP/SISCAP concepts, photodetectors and other emerging III-V active-device architectures.

This role combines semiconductor physics, quantum-engineered heterostructure design, photonic modelling, high-speed device engineering, fabrication-aware optimisation and experimental validation.

Design and optimise waveguide-integrated III-V active photonic devices, primarily high-speed electro-absorption modulators.

Develop complete electro-optical device models, including geometry, capacitance, resistance and high-speed response.

Prior hands-on experience of at least 3 years with III-V photonic devices is essential.

Experience with waveguide-integrated III-V modulators or photodetectors on silicon-photonics platforms is highly valued.

Strong understanding of semiconductor physics, quantum mechanics, heterostructure band engineering and optoelectronic-device operation, with practical experience in multi-quantum-well structures, electro-absorption, QCSE, carrier transport or related III-V device physics.

Ability to translate material and active-region properties into complete electrical and photonic device designs and to critically interpret simulation outputs.

Experience with relevant band-structure, TCAD, multiphysics or optical simulation tools, such as Nextnano, Synopsys Sentaurus, Silvaco Atlas, Ansys Lumerical or COMSOL.

We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium and work on advanced integrated-photonics technologies within a multidisciplinary semiconductor R&D environment.

You will collaborate with experts across materials, devices, circuits, systems and manufacturing.

You will have the opportunity to influence future integrated-photonics technologies and convert new device concepts into experimentally validated platform solutions.

We are committed to being an inclusive employer and proud of our open, multicultural, and informal working environment with ample possibilities to take initiative and show responsibility.

Through imec.academy, 'our corporate university', we actively invest in your development to further your technical and personal growth.
