Résumé du poste

Ghent University seeks a Temporary Scientific Staff Member to design and simulate III-V semiconductor lasers for integration with silicon photonic circuits. The role focuses on defining the laser's epitaxial structure, optical, electrical and thermal design and optimization of waveguide geometry to achieve high efficiency.

You will collaborate with researchers in laser fabrication, characterization, and silicon photonics, delivering reports, simulations, and mask layouts for fabrication and

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, 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.

Responsabilités

• Design and simulate III-V semiconductor lasers for integration with silicon and silicon-nitride photonic circuits.
• Define the 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, where applicable, a mask layout for subsequent fabrication and experimental validation.
• Discuss the results with researchers specialising in laser fabrication, characterisation, micro-transfer printing and silicon photonics.
