Abstract:
With the remorseless growth in demand for telecommunication services,
the capacity of optical fiber links first exceeded the capabilities of
electronics, requiring the introduction of wavelength division
multiplexing, and is now approaching a fundamental limit. This limit is
due to a trade-off between the familiar Shannon limit at low signal
powers, and nonlinear effects at high powers. Before considering the
implications of the capacity crunch when demand finally hits this limit,
this lecture will review the technological achievements which took the
industry from its first commercial service with the Dorset (UK) police
in 1975 through to the 10 Tbit/s systems of today.
Presenter(s):
Dr. Andrew Ellis was born in Underwood, England in 1965 and gained a BSc
in Physics with a minor in mathematics from the University of Sussex,
Brighton, England in 1987. He was awarded his PhD in Electronic and
Electrical Engineering from The University of Aston in Birmingham,
Birmingham, England in 1997 for his study on All Optical Networking
beyond 10 Gbit/s.
He previously worked for British Telecom Research Laboratories as a
Senior Research Engineer investigating the use of optical amplifiers and
advanced modulation formats in optical networks and the Corning
Research Centre as a Senior Research Fellow where he led activities in
high speed optical component
characterization. Currently, he heads the Transmission and Sensors Group
at the Tyndall National Institute in Cork, Ireland, where he is also a
member of the Department of Physics, University College Cork. He is also
an adjunct Professor of Electronic Engineering at Dublin City
University, and a founder of the Dublin based start-up Pilot Photonics.
He research interests include all optical OFDM, optical and electrical
signal processing, the
mechanisms limiting capacity in optical communication systems, and the
application of photonics to sensing. Dr. Ellis is a member of the
Institute of Physics and the Institute of Engineering Technology, and is
a Chartered Physicist. He is an Associate Editor of Optics Express and
acts as a reviewer for IEEE Journal of Lightwave Technology, Photonics
Technology Letters and Journal of Selected Topics in Quantum
Electronics. He has published over 150 journal papers and over 24
patents in the field of Photonics.
