  • Photonics

 In terms of his personal research accomplishments, Paul Townsend is widely-recognised as one of the founders of the field of experimental Quantum Key Distribution (QKD), being the first to demonstrate phase-encoded QKD in fibre links, multi-user networks and Wavelength Division Multiplexed (WDM) systems, whilst at BT Laboratories in the UK. The main focus of his current research at Tyndall is next generation fibre to the home networks, and in particular new large scale networks that can significantly reduce the cost and energy consumption of the whole network by eliminating unnecessary electronic switches and routers. His group has developed a number of inventions related to this, and other access or data centre applications, which are under development within his core research programme. His team’s work on long reach access has been highlighted by BT at major conferences such as the Broadband World Forum, ECOC and OFC, and is of interest to standardisation bodies such as the IEEE 802.3 Extended EPON Study Group. He collaborates widely with industry, working with some 15 companies over the last five years, including major ICT multi-nationals such as BT, Intel, Alcatel-Lucent and Nokia Siemens Networks.

 Paul Townsend was awarded a PhD in Physics from the University of Cambridge in 1987. He subsequently worked in the international communications industry with Bell Communications Research, BT and Corning, where he held research leadership positions, before moving to Tyndall/UCC in 2003. He has authored more than 170 peer-reviewed publications, including 40 invited papers, and holds granted patents in 16 families to date, with several other applications pending.  is also an Honorary Professor in the School of Engineering and Physical Sciences at Heriot-Watt University in Edinburgh and a Fellow of the Institute of Physics.
