Fully-funded PhD studentship in ‘High-Capacity Optical Fibre Networks’

A fully funded four-year PhD studentship is available to UK / EU students

Duration of study: Full time - four years fixed term

Starting date: October 2021

Application deadline: 15th of July 2021 (or until filled)

Primary Supervisor: Dr Lidia Galdino, University College London

Eligibility: UK/EU students ONLY

Applications are invited for a PhD studentship,  to work in the Optical Networks Group, Department of Electronic and Electrical Engineering, UCL) on the next generation of optical communication infrastructure and technologies to underpin the cloud connectivity.

Funding: The studentship covers Home/EU tuition fees and an annual stipend of £17,285 (2020-2021), increasing annually with inflation, together with a generous top-up of £3k per year. Additional support will cover consumables, books, professional memberships and travel to workshops and conferences.

Background: Optical fibre networks underpin the digital communications infrastructure. The next research challenge is to maximise the amount of information data that can be reliably transmitted through an optical fibre and introduce intelligence so that they are able to dynamically provide capacity where and when it is needed – transforming next-generation information infrastructure. Cloud network traffic is expected to more than double every two years and new services with high data rate requirements. Next-generation networks will need to be adaptive on different time- and length- scales and be tailored to applications requirements on capacity and delay, physical properties of the nonlinear optical transmission channels, and the information from intelligent transceivers on the network state. They will also need to handle much higher capacities – requiring access to much wider fibre bandwidths than have been used to date. This will need the application of new transmitter and amplifier technologies.

The PhD project is an experimental oriented research. The student will help us develop our recirculating optical fibre loop and a mesh network test-bed to support transmission rates above Terabit/s speeds, expand the usable optical fibre bandwidth using new amplifier and transmitter technologies. Digital transceivers to enable network intelligence using DSP and machine learning will be developed and new optical network monitoring using a combination of instrumentation and intelligent transceivers will be investigated. The Optical Networks Group (ONG) laboratory has a unique state-of-the-art lab facility that enables the study and evaluation of multi-Terabits/second ultra-wideband optical fibre transmission systems. The ONG group has recently demonstrated the new world record internet speed of 178 Tb/s. This achievement has been reported on medias worldwide, Read: https://www.standard.co.uk/tech/london-scientists-build-ultra-broadband-a4524801.html, https://www.thesun.co.uk/tech/12462020/internet-world-record-speed-netflix/.

The student will be developing technologies to further increase this the internet speed.

Qualifications required: The successful applicants will be part of the Optical Networks Group, Department of Electronic & Electrical Engineering. Applicants (UK/EU only) should be outstanding academically, ideally have 1st class (or a very good 2’1) undergraduate degree or equivalent in physics, communications or electronic & electrical engineering with a clear aptitude and enthusiasm for experimental research. The research will be primarily experimental work with a mix of theoretical modelling. The ideal candidate would have the following skills and knowledge

  • Experience of hands-on experimental work in a research environment is a significant advantage, with a preference for (but not limited to) optical communications/nonlinear optics/high- speed digital communications.
  • Understanding of optical communications
  • Scientific computer programming (e.g.,MATLAB, Pyton)

Additional information: The student will work closely with researchers on the EPSRC TRANSNET (Transforming optical networks – building an intelligent optical infrastructure) programme grant: http://www.transnet.org.uk. The Optical Networks Group at UCL has graduated a high number of very successful PhD graduates who have won a series of prizes and awards for their research, and are now working in leading academic and industrial research laboratories in the world. Information about the ONG group can be found at http://www.ee.ucl.ac.uk/ong

How to apply: Applications must be made using the UCL online application system and indicate the name “ONG/Galdino”.
