The Optical
Frequency Metrology Goup at NPL is at the forefront of developing the next
generation of atomic clocks, which operate at optical frequencies. Already
surpassing current primary standards in performance, these optical clocks are
expected to lead to a future redefinition of the second and, consequently, to
changes in the way we maintain and disseminate the national time scale
UTC(NPL).
For this
purpose we develop and operate femtosecond optical frequency combs and an
international fibre link between London and Paris. Together these enable us to
compare our optical clocks not only within NPL, but also with those developed
in other European laboratories. New facilities planned for our Advanced Quantum
Metrology Laboratory (AQML) will open up this capability to academic and
industrial users, enabling them to test and evaluate atomic clocks and laser
systems being developed as part of the UK quantum technologies programme. In
the longer term, our vision is that the AQML will sit at the hub of a pan-UK
fibre-optic network providing research institutions and industrial customers
with accurate time and frequency signals that are directly traceable to
UTC(NPL).
You will
initially join the team operating the London-Paris fibre link and driving the
development of optical time and frequency transfer at NPL. You will be
involved in European collaborative research (EMPIR project TiFOON) and will
take technical responsibility for specific tasks. You will also be involved in
the day-to-day running and development of our evolving fibre network.
This is an
opportunity to learn about and become involved in many of NPL’s time &
frequency-related activities, and ultimately to shape the future of how time is
measured. Most of the work is highly collaborative, bringing together multiple
teams from within the group and/or other European laboratories.
