About the Workplace
We are looking for highly motivated graduates to join the Optics group at Department of Theoretical Physics and Astrophysics at Faculty of Science, Masaryk University. We have rich expertise in optics, in particular light propagation in optical fibres.
Masaryk University is modern, dynamic and the most attractive university in the Czech Republic with ten faculties, more than 6500 staff and 33 000 students, a wide range of research areas and a strong international position. We are the largest academic employer in the South Moravian Region.
Faculty of Science MU, a holder of the HR Excellence in Research Award by the European Commission, is a research-oriented faculty, offering university education (Bachelor’s, Master’s, and Doctoral degree programs) closely linked to both primary and applied research and high school teaching of the following sciences: Mathematics, Physics, Chemistry, Biology, and Earth sciences. We are the most productive scientific unit of the Masaryk University generating around 40 % of MU research results.
Description
Optical fibres are the backbone of modern civilization. But what if the very cables carrying our data could also be used to eavesdrop on our voices? This PhD project investigates the Acousto-Optical effect, where acoustic waves (sound) subtly deform optical fibres, creating detectable changes in light propagation. We are looking for a driven researcher to explore these mechanisms, assess the security risks of fibre-based interception, and develop countermeasures to protect communication networks.
Selected student will have an opportunity to:
· Investigate detailed mechanisms of acousto-optical interaction in various types of optical fibres.
· Assess the real-world risks of communication interception and propose mitigation strategies.
· In collaboration with our partner institution at Brno University of Technology, utilize high-stability laser light and scattering analysis to reconstruct acoustic signals.
Offered Conditions
Selected candidates will receive a comprehensive guidance and training in various fields of modern physics.
Besides, studying at our Faculty is an opportunity to study and live in a modern and dynamic city and one of 10 best student cities worldwide.
In addition to the standard PhD scholarship at Masaryk University (CZK 15 000 per month), additional funds are provided through departmental resources (assignment in research projects, additional scholarships). An overall monthly income is typically around CZK 30 000, which provides a stable income more than sufficient for a comfortable student life in the Czech Republic.
Additional support includes performance-based bonuses (scholarships for successfully published papers) as well as support for international mobility or attendance of conferences etc.
Required Skills and Qualifications
· Master degree in Physics (required at the time of enrolment to the PhD study program).
· Solid understanding of optics and theory of electromagnetic fields.
· Advanced skills in MATLAB, Python, or similar languages for data analysis and simulation.
· Fluency in English (written and oral).
· Strong commitment to research excellence and completing the PhD studies.
How to Apply
Please send your curriculum vitae, cover letter with a concise summary of your previous research activities to
Faculty of Medicine, Masaryk University, Kamenice 5, 62500 Brno, Czech Republic
Professor Tomas Tyc, tomtyc@physics.muni.cz
Selection Process
Received applications will be continuously reviewed and carefully considered. Shortlisted applicants meeting the requirements will be invited to an interview.
Please note that your application does not substitute an official admission process to Ph.D. studies at SCI MUNI. Details including discussion about the research topic, required documentation or formalities will be a subject of the interview with successful candidates. Only upon the informal pre-agreement with potential future supervisor, a formal application for PhD studies at Faculty of Science, Masaryk University can be submitted.
We are looking forward to hearing from you!
