PhD position: Nano Photonics with Fibre Cavities

Your position

We aim to develop micron-scale fibre cavities with excellent in-and-out coupling efficiencies and with designer nano-structured mirror profiles. Rapid, flexible and scalable nano-fabrication techniques will be developed based on femto-second laser ablation. Two light sources will be developed with the same fibre cavity: a high-repetition rate pulsed laser for optical telecommunications, and a single-photon source for quantum technology.

Your aim will be to:

• generate and characterize sub-micron size Bessel beams
• perform nano-machining trials of glass samples with a femtosecond pulsed laser and optimize laser parameters for the optimal mirror template
• design and build open micro-cavities with nano-machined fibres for quantum communications
• design and build a micro-cavity femtosecond laser for high data rate telecommunications

Work places:

• Nano-machining and micro-cavity fs laser tasks at University of Applied Sciences and Arts Nortwestern Switzerland in Windisch/Brugg, ~30 minutes from Zürich, ~45 minutes from Basel
• Fibre cavities for quantum communications at University of Basel in the center of Basel

Your profile

• BS or MS degree in physics, photonics, engineering, or a related field
• Highly motivated for applied experimental laboratory work
• Experience with femtosecond lasers and/or quantum optics is a plus
• Experience with scientific programming and data analysis (Python, MATLAB, or similar) is a plus
• Communication and team-working skills
