| Introduction |
|
 |
Richard Penty's first foray into the world of optical communications was via a sponsorship with the National Coal Board for whom he designed a 1Mb/s optical line card. He graduated from the University of Cambridge with a degree in Engineering and Electrical Sciences in 1986 and a PhD for research into nonlinear optical fibre devices in 1990. Richard was then an SERC IT research fellow at Cambridge until taking up a lectureship in physics at the University of Bath in 1990. In 1996 he moved to the University of Bristol as a lecturer in electrical and electronic engineering subsequently being promoted to Professor of Photonics. In 2001 he moved to the Cambridge University Engineering Department and was elected to a fellowship of Sidney Sussex College in 2002.

Richard's research interests include optical data communications, MMF systems (digital and analogue), high-speed optical communications systems, wavelength conversion and WDM networks, optical amplifiers, optical non-linearities for switching and routing applications, RF over fibre and high power semiconductor lasers.
Richard is the co-author of in excess of 300 refereed journal and conference papers. He manages the semiconductor laser workpackage of the PHOTON project and is one of the UK representatives on the EU COST 267 management committee.
