General description

The Optical Networks Group (ONG) group studies optical communications, operating on all time and length scales. We are interested in all linear and nonlinear phenomena related to the propagation of optical signals in different media, including different types of fibres and free-space. Our current research is focused on: Network architectures: wide-area, access & interconnects Network routing and control: adaptive, dynamic & intelligent High-speed transmission systems: use of advanced modulation formats, optimised detection and digital signal processing to increase system and network capacity in a variety of fibre types ONG is currently comprised of over a dozen academic and research staff and a similar numbers of PhD students. The ONG optical networks and systems laboratory at UCL is the leading optical transmission research lab in the UK. We are currently focused on characterising the performance of 100 Gb/s wavelength division multiplexed systems using advanced modulation formats in conjunction with coherent detection over transmission distances of up to 30,000 km. This laboratory is based around an optical fibre recirculating loop test-bed and a comprehensive signal generation and detection capability.

As per COFUND guidelines, fellowship programmes will be based on individual-driven mobility, i.e., researchers will be able to freely choose a research topic fitting their individual needs.

The subject of the research project is expected to contribute to European competitiveness and to be in the general field of Photonics and/or its applications. Within these limitations, applicants can freely choose both their research topic and their host organisation, in the spirit of the ‘European Charter for Researchers’.
