    Professor Graham T. Reed

    Graham Reed, BSc, PhD, FIET, CEng, is Professor of Silicon Photonics at the University of Southampton, UK. In April 2012, he joined Southampton from the University of Surrey, where he was Professor of Optoelectronics, and was Head of the Department of Electronic Engineering from 2006 to 2012.

    Reed is a pioneer in the field of Silicon Photonics, and acknowledged as the individual who initiated the research field in the UK. He established the Silicon Photonics Research Group at the University of Surrey in 1989. The first Silicon Photonics company in the world, Bookham Technology Inc., was founded by Reed’s PhD student, Dr Andrew Rickman, and adopted the research developed in the Group. Bookham (now renamed Oclaro Inc) is one of the leading optical sub-system companies in the world. Reed’s Silicon Photonics Group have provided a series of world leading results since its inception, and are particularly well known for their work on silicon optical modulators. For example, the Group produced the first published design of an optical modulator with a bandwidth exceeding 1 GHz, and were the first to publish the design of a depletion mode optical modulator, which is now a technology standard device. More recently the team were responsible for the first all-silicon optical modulator operating at 40Gb/s with a high extinction ratio (10dB), as well as a second modulator design (also operating at 40Gb/s) that operates close to polarization independence. They also reported the first device operating at 50Gb/s.

    Reed is a regular invited and contributing author to the major Silicon Photonics conferences around the world. He has served on numerous international conference committees, and has also chaired many others. To name but two, he has been co-chair, of the Silicon Photonics symposium at SPIE Photonics West conference in San Francisco since it was first established in 2006, and in 2011 he was co-chair of the most prestigious Silicon Photonics conference, IEEE Group IV Photonics, held at the Royal Society in London, the latter being the most well supported conference in the history of the event. He is currently a member of 5 international conference committees, and has published over 300 papers in the field of Silicon Photonics. In 2013 he was the recipient of the IET Crompton Medal for Achievement in Energy, for his work on Silicon Photonics, and in 2014 he was awarded a Royal Society Wolfson Merit Award.

    He currently leads the £6.2M (approx. $10M) “Silicon Photonics for Future Systems” programme, a UK research programme funded by the EPSRC, as well as the £3.3M ($5.4M) “CORNERSTONE” project (also EPSRC funded), as well as several smaller.

  • Professor Roger Webb +

    Professor Roger Webb

    Roger joined the Department in 1983 as a Research Fellow with the SRC (as it was then - interesting how the EPSRC has gained letters over the years) Surrey Ion Beam Centre. He was employed to look after the computing facilities associated with the research group - a single pdp11, about half of the computer "power" in the department in those days.

    Before this he had spent 3 years as a post doc at the Naval Postgraduate School in Monterey California, making Molecular Dynamics Studies and Computer Animations, which is still the main area of his research activities. He did his PhD work in the Electronic & Electrical

    Engineering Department of the University of Salford, on the Mathematical Modelling of Atomic Collisions in Solids.

    He was made a Lecturer in the Department in 1986, promoted to Senior Lecturer in 1993 and then to Reader in 1997, reaching the dizzy heights of Professor of Ion Beam Physics in 2002. He is the current Director of the Surrey Ion Beam Centre.

    He has performed research at Penn State College and the Chinese University of Hong Kong.
