Senior III-V Photonics Modulator Engineer

Karlstad University; Heverlee; Sur place; EUR 70 000 - 110 000; Plein temps

Résumé du poste

Imec in Leuven is seeking an R&D Engineer to design and validate waveguide-integrated III-V active photonic devices, focusing on QCSE electro-absorption modulators on silicon-photonics platforms.

You will combine semiconductor physics, device modelling and fabrication-aware optimisation to translate concepts into tested layouts and measured data, collaborating across epitaxy, integration, process and circuits.

Qualifications

• PhD in electrical engineering, photonics, applied physics, semiconductor physics, materials science or a closely related discipline.
• 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.
• Ability to translate material and active-region properties into complete electrical and photonic device designs.
• Experience with band-structure, TCAD, multiphysics or optical simulation tools such as Nextnano, Synopsys Sentaurus, Silvaco Atlas, Ansys Lumerical or COMSOL.
• Scientific programming capability in Python or equivalent, including automation and data analysis.

Responsabilités

• Design and optimise waveguide-integrated III-V active photonic devices, primarily high-speed electro-absorption modulators.
• Engineer multi-quantum-well heterostructures for target wavelength, optical loss, voltage and speed.
• Model band structure, QCSE, carrier transport, optical absorption and electric-field distribution.
• Develop complete electro-optical device models, including geometry, capacitance, resistance and high-speed response.
• Design III-V integration with silicon/silicon-nitride waveguides and optimise coupling.
• Incorporate epitaxial, process, thermal and manufacturing constraints into robust device designs.
• Translate concepts into layouts and test structures, then correlate simulations with measurements.
• Collaborate across epitaxy, integration, process, characterisation, circuits and systems; contribute to roadmaps, IP and publications.
