Bojan Resan

PhD position in Nano Photonics with Fibre Cavities (P2605) at the University of Basel , Switzerland, in collaboration with the University of Applied Sciences and Arts Northwestern Switzerland. The project sits at the intersection of ultrafast laser technology , nanophotonics , quantum optics , and optical telecommunications . Two research groups are involved: the Photonic Ultrafast Systems Group led by Prof. Bojan Resan and the Nano-Photonics Group led by Prof. Richard Warburton . The work aims to develop micron-scale fibre cavities with excellent in-coupling and out-coupling efficiencies and designer nano-structured mirror profiles. Rapid and scalable nanofabrication will be explored via femtosecond laser ablation . The successful PhD candidate will work on generating and characterizing sub-micron Bessel beams, performing nano-machining trials on glass samples, optimizing laser parameters for mirror template design, building open micro-cavities with nano-machined fibres for quantum communications, and designing a micro-cavity femtosecond laser for high-data-rate telecommunications. The project offers a highly interdisciplinary environment spanning state-of-the-art ultrafast experiments in Windisch/Brugg and quantum optics experiments in Basel. The position is part of the Swiss Nanoscience Institute (SNI) PhD school , which supports around 30 scientists and provides a collaborative research environment, training in soft skills, social events, and a competitive Swiss PhD salary. The broader SNI community covers quantum physics and chemistry, nanotechnology, materials science, biochemistry, cell biology, and medical research. Eligibility: BS or MS degree in physics, photonics, engineering, or a related field; strong motivation for applied experimental laboratory work; experience with femtosecond lasers and/or quantum optics is advantageous; experience with Python, MATLAB, or other scientific programming/data analysis tools is also a plus; communication and teamwork skills are important. Application: Apply online via www.phd.nanoscience.ch or the direct application link. Questions may be directed to Dr. Andreas Baumgartner at [email protected] or to the project leaders. The vacancy can be filled any time from now, and the application must be completed by 31 December 2026 ; the posted deadline in the listing is 2026-10-15 .
