Summary: The unprecedented growth of optical communications has underpinned the broadband communications and the Internet, enabling e-commerce, video-on-demand, telepresence and high-performance distributed computing. The development of the optical fibre infrastructure has dramatically changed the whole landscape of public, business and government activities, stimulating relentless traffic growth. According to Cisco’s Visual Networking Index, the annual global IP traffic will exceed three-quarters of a zettabyte (767 exabytes) by 2014. Global IP traffic will quadruple from 2009 to 2014. Despite a huge global optical communication infrastructure, the demand for ever-higher communication bandwidth, with reduced cost and power consumption per bit strains the capability of this infrastructure to satisfy it. Despite the extraordinary developments in optical communication research, the continuing growth in network traffic means that by 2020 traffic growth will exceed capacity growth of the existing or installed fibre infrastructure by a factor of 10! The aim of the research is to develop, through theory and experiment, ground-breaking and visionary concepts to unlocking the capacity of future information systems that go beyond the limits of current optical communications technology. Our approach is focused on the need to quantify, for the first time, the fundamental limits of nonlinear channels carried over optical fibres. Saturation of the capacity of the communication systems will have detrimental impact on the economy and social progress and public, business and government activities. The aim of the research is to develop, through theory and experiment, disruptive approaches to unlock capacity of future information systems. Combining techniques from information theory, coding, study of advanced modulation formats, digital signal processing and advanced photonic concepts to make possible breakthroughs that go beyond the limits, for the systems beyond tomorrow.
