PhD position on Microresonator-based Frequency Combs

Project Description

This is an exciting opportunity for a highly motivated early stage researcher (PhD student) to join our group to work on microresonator-based optical frequency combs for optical clocks and photonic sensor technologies. The position will be at the Max Planck Institute for the Science of Light (MPL) in Nuremberg/Erlangen.

This work will use ultra-high-Q microresonators, which enable the confinement of extremely high levels of optical power into tiny micron-scale volumes. This allows nonlinear optical effects to be observed at extremely low threshold powers, making microresonators ideal components for future generations of integrated photonic circuits. MPL has state-of-the-art cleanroom and advanced fabrication facilities for ultra-high-Q microresonators.

The skilled candidate will work on microresonator-based frequency comb systems for use in the next generation of optical clocks and in chip-based photonic integrated circuits. Optical clocks are currently the most precise instruments for time measurements and will most likely replace caesium microwave clocks as the standard for the definition of the second within the next decade. Microresonator-based frequency combs are promising tools to enable precise readout of the next generation of compact and portable optical clocks.

The ideal candidate will be qualified in physics, electronic engineering or a related subject. The ideal candidate will have experience in research areas such as:

- photonics
- fiber optics
- laser physics
- microresonators
- nonlinear optics
- digital and analogue electronics

The candidate must not have been awarded a PhD at the time of their recruitment. The candidate will be typically enrolled in a PhD programme at the Friedrich Alexander University Nuremberg Erlangen.

The position includes a competitive salary.
