Dr Wladek Forysiak studied Physics at Imperial College, London and then joined the Physics department at Heriot-Watt University, Edinburgh, and received a PhD for studies on Nonlinear Dynamics of Three-Level Lasers in 1989.
Following post-doctoral appointments at Heriot-Watt University, Aston University and The University of Arizona, he joined the Department of Electronic Engineering at Aston University in 1996 as a lecturer and was promoted to reader in 2000. During that period he taught several UG and MSc-level courses in electronic engineering and telecommunications, and performed research on high-speed optical fibre transmission systems via numerical simulations, with emphasis on optical solitons, dispersion management, and WDM.
In 2000, he moved to Marconi Solstis as Development Director alongside five colleagues from Aston to develop an ultra-long-haul DWDM transmission system, named uPLx160. From 2003-2010 he worked for Marconi plc, and subsequently Ericsson Ltd, as Photonics Modelling Manager leading an international team responsible for propagation modelling, simulation tools, and link configuration design rules. In 2010, Wladek was appointed Director, technology and systems at Oclaro Technology Ltd, where he worked for the Optical Network Systems Business Unit, with interests in optical communication systems, high-bit-rate modules, advanced amplification, and related technologies.
In 2012 he was appointed Royal Society Industry Fellow at AIPT to work on a research project entitled “Tackling Information Capacity limits to Tbit/s fibre Optic Communication systems” (TICTOC) and in July 2014 appointed as a Senior Lecturer in Applied Physics at Aston. He has been a TRANSNET Co-Investigator, based at our Aston University site since 2018.

TRANSNET Deputy Director
I graduated from the Department of Physics of the Novosibirsk University, Russia in 1982 and received my Ph.D. degree in Theoretical and Mathematical Physics from the Institute of Nuclear Physics, Novosibirsk, Russia in 1986.
From 1992 to 1998 I worked in the Institute for Theoretical Physics I, Heinrich-Heine University Duesseldorf, Germany; first as a Humboldt Fellow and then within the collaborative projects with Deutsche Telekom. I joined the Photonics Research Group in the School of Engineering and Applied Science, Aston University in 1998.
During last two decades I have been working on various problems of nonlinear science, including soliton theory, self-focusing of light beams, discrete nonlinear systems, and nonlinear fibre optics. My recent research has been shifted towards the high-speed optical communications, nonlinear photonic devices, Raman-based technologies, and ultra-long fibre lasers. Since 2005, I hold the Royal Society Wolfson Research Merit Award. I have been Deputy Director on the TRANSNET grant since 2018.
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.
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
