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

We offer you

Interdisciplinary work in a highly collaborative environment
A unique environment combining state-of-the-art ultrafast experiments at University of Applied Sci-ences and Arts Northwestern Switzerland with state-of-the-art experiments in quantum optics at University of Basel
Close collaboration with internationally recognized experts in ultrafast optics, micromachining and quantum communications
The opportunity to pioneer innovations in the emerging field of fibre cavities with applications ranging from fundamental quantum physics to future photonic telecommunications
