Project Description

This is an exciting opportunity for a highly motivated early stage researcher (PhD student) to join NPL’s Time and Frequency group to work on microresonator-based optical frequency combs for optical clocks and on dual-comb spectroscopy. The position is funded by the European Commission via a Marie-Sklodowska-Curie Innovative Training Network on microresonators based frequency combs (Project “MICROCOMB”,

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. NPL has a 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. 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 of one of NPLs University partners (eg. Imperial College, Oxford, University of Strathclyde, Heriot Watt University).

Mobility rule: The candidate must not have resided or carried out their main activity in the United Kingdom for more than 12 months in the last 3 years prior to recruitment.

The position includes a competitive salary. Exact salaries are based on MSCA ITN funding rules, including living allowance, mobility allowance and family allowance (according to eligibility).

The PhD position will be based in Teddington, which is located south-west of London (~35 minutes by train to Central London). The position will support travelling to conferences and workshops.
