Barbara Piętka

Postdoctoral Researcher (Adjunct) position in Experimental Polariton Photonics and Neuromorphic Computing at the Center for Theoretical Physics, Polish Academy of Sciences in Warsaw, Poland. The role is part of the Q-ONE project, Quantum Optical Networks based on exciton-polaritons , funded by the European Commission under Horizon Europe / EIC . The successful candidate will join the Light-Matter Interaction Group led by Prof. Michał Matuszewski and collaborate closely with the experimental group of Prof. Barbara Piętka at the Faculty of Physics, University of Warsaw . Employment is at CTP PAS, while laboratory work will be carried out mainly at the University of Warsaw’s advanced experimental infrastructure. This is a strongly experimental postdoc focused on developing optical experiments that demonstrate neuromorphic functionalities in polaritonic systems. The project combines nonlinear optics , semiconductor physics , photonic microstructures , and artificial intelligence , with an emphasis on implementing neural-network operations directly in a physical optical platform. Research topics include exciton-polaritons , strong light-matter coupling at room temperature, optical microcavities, perovskite materials, polariton propagation, condensation, pattern recognition, and optical information processing. Responsibilities include building and optimizing optical setups, performing spectroscopic and optical characterization of semiconductor and photonic structures, investigating nonlinear polariton phenomena, designing and running experiments for neuromorphic and neural-network operations, analysing data, using simple models and simulations, preparing publications, and presenting results at conferences and workshops. The role is full-time, on-site, and offers a salary of PLN 12,000-16,000 gross per month . The appointment is fixed-term for up to 9 months , starting from 1 November 2026 at the earliest. Applicants should hold a PhD in physical sciences or a related discipline, ideally in optics, photonics, condensed matter physics, semiconductor physics, or photonic engineering. Prior doctoral completion may still be acceptable if the degree will be conferred before employment starts and the current stage of the award procedure is documented. Experience with experimental optics/photonics, optical laser setups, quantitative data analysis, basic programming (Python/MATLAB), and excellent English are important. Desirable experience includes exciton-polariton physics, semiconductor microcavities, perovskites, nonlinear or time-resolved spectroscopy, waveguides, photonic networks, experimental automation, numerical modelling, and interest in neuromorphic photonics or optical neural networks. Applications should be emailed to [email protected] by 1 October 2026 with reference number MM/22/2026 in the subject line. Required documents include an academic CV, cover letter, PhD diploma or proof of doctoral status, optional proof of achievements, at least one recommendation letter sent directly by the referee, and a signed personal data protection statement.
