PhD position: Nano Photonics with Fibre Cavities

This PhD position is a collaborative research opportunity between the Photonic Ultrafast Systems Group and the Nano-Photonics Group. The project focuses on developing micron-scale fibre cavities with designer nano-structured mirror profiles using femtosecond laser ablation. The successful candidate will work on two primary applications: creating a high-repetition rate pulsed laser for optical telecommunications and a single-photon source for quantum technology. The role involves experimental work across two sites, the University of Basel and the University of Applied Sciences and Arts Northwestern Switzerland. You will join the Swiss Nanoscience Institute (SNI) PhD school, benefiting from a highly collaborative environment and comprehensive training.
