The practical and theoretical techniques and associated systems for transporting information by fibre-guided or free-space photons, including analogue and digital signals. This area contains research aiming to increase the capacity, speed, flexibility, availability, efficiency and security of optical communications on all length scales, from sub-micron (intra-chip) to mega-metres (transoceanic links). It can include, for instance, optical signal generation and processing for advanced modulation formats, transmission and switching (including wavelength, space, polarisation and time division multiplexing). This area also addresses intelligent networking, including integration with wireless communications and non-linear optical techniques.
The strategy for this research area recognises the UK strength in this area and the contribution it makes to the communication of information in an increasingly connected world. The UK community is in a good position to respond to challenges originating from future demands to increase capacity in the optical communications network due to the continued development of Information and Communications Technologies (ICT) under the influence of both Big Data and the Internet of Things.

By the end of the current Delivery Plan, we aim to have a research area which:
The international landscape is moving towards a converged, cross-disciplinary approach to communications. While this research area does not require further specific stimulus, then, it should continue to maximise the impact of research undertaken within it by adopting an approach that encourages systems thinking beyond the traditional Optical Communications domain. This requires efforts to bring about greater interaction in future between this research community and others, and in particular with the Radio Frequency and Microwave Communications community in terms of addressing the cross-disciplinary challenges that need to be overcome to enable the development of 5G networks.
Highlights:In this research area, the UK features some very strong groups at the forefront of their fields, with strong research capability spanning many aspects of Optical Communications research, from components to systems and network architectures. (Evidence source 2,3,4,5,6,7) The UK is unique in its coverage of many communications research areas and has made major contributions to the development and use of fibre optics, as well as in pioneering specialist research (e.g. free-space Optical Communications) and disruptive technologies (e.g. Light Fidelity, or LiFi). (Evidence source 3,5)
The groups active in this area are well-connected, with numerous collaborations at both national and international level, and this is supported by a healthy industry strongly engaged with leading research groups. (Evidence source 1,6) Many parts of industry are relevant beyond ICT - extending into healthcare, manufacturing and energy - and the research area-s grant portfolio reflects this. (Evidence source 4)
Concentrated among a small number of key institutions, the community is capable of attracting both UK and international academics and students. (Evidence source 2,3,4,8) The UK can support this community at different career stages through a mix of different mechanisms, suggesting that the UK is not at risk of losing capacity.
This area is well-supported by extensive and in some cases unique infrastructure, including cleanrooms, large equipment and facilities such as the expanding National Dark Fibre Infrastructure Service established in 2014 and the National Hub in High Value Photonic Manufacturing established in 2015. EPSRC funding for linking network testbeds has been awarded to projects working to link optical and wireless communications and therefore accelerate the impact of Optical Communications research in this area. (Evidence source 1,4,8)
This research area has the potential to contribute to Connected, Productive and Resilient Nation Outcomes in the short and long term, and the following specific Ambitions within these Outcomes:
Recent developments in the field (e.g. LiFi) have shown the potential.
This research area will enable communications paradigms for novel network architectures involving multiple devices.
This area is relevant to future internet and communications networks.
