Université de Namur is advertising a PhD position in numerical photonics within the MSCA doctoral network SPARK . The project is titled “Optical Vortex Generation Using Twisted Bilayer Photonic Crystals” and focuses on photonics, optics, electromagnetism, numerical simulation, scientific computing/HPC, nanofabrication, and structured light . The successful candidate will join the Lobet research team at the University of Namur (Science Faculty / Physics Department, NISM institute). The work combines theoretical modelling and numerical calculations with experimental fabrication and characterization in the emerging area of moiré optics . The project aims to design twisted photonic crystals that generate robust optical vortices carrying orbital angular momentum. Training and secondments are a major part of the position: 3 months at IMEC for nanofabrication exposure and 6 months at INESC MN for structured-light characterization using off-axis digital holography. The candidate will also benefit from collaboration across the SPARK consortium and access to HPC resources (CECI, regional Tier-1, EuroHPC). Funding: the position is funded through Horizon Europe / MSCA for 36 months, with an additional 12 months funded by UNamur to complete the thesis. Gross salary starts around 3000€/month , with possible mobility and family allowances depending on eligibility. Eligibility highlights: a Master’s degree in physics, astrophysics, applied physics, optics, electrical engineering, material engineering, computer science, mathematics, technology, or a closely related field; no doctoral degree at recruitment; and compliance with the MSCA mobility rule (not more than 12 months in Belgium during the 36 months before recruitment). Strong English is required; French at basic level is listed. How to apply: prepare a CV, master course list with ECTS and grades, motivation letter, up to 3 referees, and any other relevant documents.
