Résumé du poste

Ghent University’s Photonics Research Group seeks a Temporary Scientific Staff Member to design and simulate III‑V semiconductor lasers for integration with silicon photonics. You will define laser structures and optimize performance for a three-month project, collaborating with fabrication and research teams.

The position requires a Master’s degree or PhD in photonics or related field and strong experience in numerical modelling with tools such as Lumerical or COMSOL.

Qualifications

• Master's degree or PhD in photonics, electrical engineering, applied physics or closely related field.
• Demonstrable knowledge of III-V semiconductor-laser physics and design (Fabry-Perot, DFB, DBR or external-cavity).
• Experience with numerical modelling of optical components using software such as Ansys Lumerical, COMSOL, Photon Design or comparable tools.
• Knowledge of waveguide modelling, carrier transport, thermal effects, coupled-mode theory or laser rate-equation models is an asset.
• Experience with photonic layout, fabrication tolerances or heterogeneous integration is an asset.
• Work independently with a strong focus on results; document design decisions and simulations carefully.
• Fluent English; Dutch is an asset but not required.

Responsabilités

• Design and simulate III-V semiconductor lasers for integration with silicon and silicon-nitride photonic circuits.
• Define epitaxial layer structure and the optical, electrical and thermal design of the laser.
• Optimize parameters including waveguide geometry, modal overlap, mirror or grating structures, threshold current, output power and efficiency.
• Assess fabrication tolerances and the optical coupling between the III-V laser and the passive photonic circuit.
• Use numerical simulation software and establish a reproducible design and simulation workflow.
• Deliver a design report, simulation files and mask layout for fabrication and validation.
• Discuss the results with researchers specializing in laser fabrication, characterisation, micro-transfer printing and silicon photonics.
