About the position
Doctoral Candidate position at the Department of Physics, University of Namur, Belgium
Objectives:
The project will explore the generation of optical vortices carrying orbital angular momentum from twisted photonic crystal structures. The goal is to design twisted photonic crystals to realize robust vortex radiation. Secondments include 3 months at IMEC for nanofabrication exposure and 6 months at INESC MN (M. Piccardo) for structured-light characterization based on off-axis digital holography. By producing robust vortex beams via twisted photonic platforms, the doctoral candidate contributes to one of the research objectives of SPARK , which is to demonstrate metamaterial-enabled structured light generation through controlled angular momentum. Over the course of the thesis, the candidate will develop skills in theoretical modelling and simulation of twisted photonic crystals (UNamur), nanofabrication of photonic structures (IMEC), and structured-light characterization (INESC MN), gained through secondments as well as shared expertise with the whole SPARK doctoral network consortium.
Starting date: February 2027
Qualifications
- Master’s degree in fields of physics, astrophysics, applied Physics, Optics, Electrical Engineering, Material Engineering or a closely related subject.
- You should not have a doctoral degree at the time of recruitment.
- You must not have resided or carried out your main activity (work, studies, etc.) in Belgium for more than 12 months in the 36 months immediately before the recruitment (this is a requirement from the funding authority).
- Strong skills in the English language.
