TRANSNET Co-Investigator

David Ives was born in the UK. He received the BSc degree in physics from the University of Birmingham UK, in 1988.

He spent 21 years at the National Physical Laboratory in Teddington, UK, as part of the Photonics group. He worked on the development of techniques for optical fibre and waveguide characterisation and optical fibre test equipment calibration. He had a strong interest in polarisation effects and properties of optical fibre and in optical time domain reflectometry, OTDR.

In September 2010 he joined the Centre for Doctoral Training in Photonic Systems Development at UCL (University College London) and obtained the degrees of MRes (2011) and PhD (2015). His PhD research was with the Optical Networks Group at UCL looking at the optimisation of wavelength routed optical networks to maximise data throughput while strongly considering the nonlinear transmission impairments for coherent optical communications. His PhD thesis titled "Coherent Optical Fibre Networking in the Nonlinear Regime" is available as a PDF.

He is currently working as a Research Associate on the EPSRC funded project INSIGHT: Introducing Insight into the Abstraction of Optical Network Infrastructures. This joint project intends to merge the knowledge of physical layer transmission impairments from UCL with that of network virtualisation from Bristol University to create robust abstractions of the physical layer suitable for the creation and control of coexisting virtual networks. In February 2016 this work moved to the Centre for Photonic Systems at the University of Cambridge.

Dr Seb Savory

TRANSNET Co-Investigator

My research is focused on optical fibre communication, whereby digital data modulates light that is then transmitted over huge distances using optical fibres. According to the 2009 IEEE ROGUCCI report, over 99% of all long distance international data traffic is carried using optical fibres and as such they underpin the internet and today’s global communication infrastructure. It is rich area of research, which encompasses both the theory and practice of engineering, ranging from developing new science, mathematics and technology to understanding the environmental, economic and societal impact which these optical fibre communication systems have on today’s global community. It is an area I have found fascinating that I have been actively carrying out research in for almost twenty five years. I have been TRANSNET Co-Investigator since 2018. 

 My current research explores four areas:

1.Algorithms for digital coherent transceivers.
2.Ultra-dense passive optical networks.
3.Statistical optical communication system design.
4.Cognitive optical networks
