The Internet is formed by a huge global web of optical fibre, connecting cities and continents by crossing the oceans and transporting more than 99% of all internet traffic data. The growth of the “Internet of Things”, video services and social media means data traffic is growing at an ever-increasing rate. The world record capacity of 120 Tbit/s transmitted over a single mode fibre was experimentally demonstrated by the Optical Networks Group at UCL in partnership with Xtera communications.
The maximum information throughput in an optical fibre depends on transmission bandwidth and the signal-to-noise ratio, which defines the signal quality. Optical fibres have more than 50THz of available transmission bandwidth, defined by the low-loss wavelength region of glass, but only 20% of this potential has been explored by the researchers and commercial systems. This is mainly due to bandwidth restrictions imposed by the long-established erbium-doped fibre amplifier (EDFA).
The PhD project will investigate broadband optical amplifiers technologies and all optical components that operate across the entire 50THz of spectrum to support next generation of optical networks. Of particular focus and interest to be explored are wavelength converters for signal generation; ultra-wideband SOA and Raman amplifiers for signal amplification; and optical fibre modelling to predict the performance of ultra-wideband transmission systems.
Candidates should have or expect to achieve an excellent degree(s) (BEng/MEng/MSc) in Electronic Engineering, Computer Science or related discipline. The research will include a mix of theoretical and experimental work, and the ideal candidate should have the following skills and knowledge:
Understanding of optical communications
Scientific computer programming (e.g.,MATLAB)
The PhD student will be part of the UCL’s Optical Networks Group, a world-leading team working on the next generation of optical communication systems.
