Speaker information

Polina Bayvel, Professor of Optical Communications and Networks, and Head of the Optical Networks Group at UCL

Some of the greatest scientific and technological successes of the past 50 years are from communications. Most of the data we generate and receive (whether emails, tweets, videos or mobile calls) are now carried by optical fibres, which use light to transmit vast quantities of information over trans-oceanic distances. The use of hundreds of wavelengths (colours of light), over, a single fibre, as well as other properties of light: its amplitude, phase and polarisation, have led to increases of many orders of magnitude in the optical information carrying capacity. This sparked the communication revolution and the growth of the Internet, and created an illusion of infinite capacity being available. But as the amounts of data increase, is there a limit to the capacity of an optical fibre communication channel? Professor Bayvel will describe the challenges and limits of communicating with light and the advances in optical and digital signal processing to maximise optical network capacity.
