Researchers from The (ORC) reveal a breakthrough in optical fibre communications.
Dublin, January 2015

Researchers from the Optoelectronics Research Centre (ORC) at the University of Southampton working with Eblana Photonics Inc, in Ireland, have revealed a breakthrough in optical fibre communications in a paper published in the prestigious journal Nature Communications.

ORC - Coherent signal synthesiser.

Academics from the ORC have collaborated with colleagues at Eblana Photonics Inc, in Ireland, to develop an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals.

The paper, entitled Modulator-free Optical QAM Signal Synthesis, explores a radically new approach to the generation of spectrally-efficient advanced modulation format signals as required in modern optical communication systems [more].

This new technology, patented by the University of Southampton and licensed to Eblana Photonics Inc, avoids the need for costly and power-inefficient external modulator schemes that are currently used to generate such signals.

Dr Radan Slavík, Principal Research Fellow at the ORC, said: "Our paper highlights the exquisite control that we have achieved over the optical field generated directly from a current-modulated semiconductor laser."

Direct current modulated lasers are of huge commercial relevance and are already widely used in optical communications, telecommunications and sensor and high power fibre laser systems. However, the inability to accurately control the full optical field emitted directly from such lasers has been a fundamental problem limiting applications.

Radan explains: "The new capability we have demonstrated will be of relevance and could be of significant impact within many scientific and engineering communities that are directly concerned with or exploit laser radiation.

"We have previously presented some of the results included in this paper at conferences, including a post-deadline presentation at Optical Fibre Communications (OFC), and at an international symposium and this has already generated a lot of interest from senior academics in our community, as well as from leading industrial players.

"Having our results published in Nature Communications, a prestigious scientific journal, represents great recognition for the work we are doing and the advances that we have made", he concluded.

Dr. Rob Lennox, Director of Sales at Eblana, said "We are very pleased to have collaborated on this innovative development work performed by the ORC team and are looking towards making this new approach a commercial reality."

The paper was co-authored by Zhixin Liu, Radan Slavík, and David J. Richardson from the ORC, Brian Kelly, John O'Carroll, and Richard Phelan from Eblana Photonics Inc, and former Southampton PhD student Joseph Kakande, now at Alcatel-Lucent's Bell Labs in the USA.

Preventing gridlock
Dublin, November 25th 2011 [read]

To keep pace with society's ever increasing data-transmission requirements, a new project funded under the EU 7th Framework Programme is set to develop the next generation internet infrastructure to enhance the capacity of broadband core networks providing increased bandwidth of 100 times current capacity

The 11.8m Euro MODE-GAP project will seek to provide Europe with a lead in the development of the next generation internet infrastructure. Combining the expertise of eight world-leading photonics partners, MODE-GAP will develop transmission technologies based on specialist long-haul transmission fibres, and associated enabling technologies such as novel rare-earth doped optical amplifiers, transmitter and receiver components and data processing techniques to increase the capacity of broadband networks.

If successful, the MODE-GAP technology will have a significant impact in enabling 'future proof networks and systems' of 'increasing information throughput'. Without such a breakthrough the internet of the future could be severely compromised.

Led by the University of Southampton's Optoelectronics Research Centre, this collaborative project brings together the expertise of leading industrial and academic organisations across Europe: Phoenix Photonics Ltd, ESPCI ParisTech, OFS Fitel Denmark APS, the COBRA Institute at Technische Universiteit Eindhoven, Eblana Photonics Ltd, Nokia Siemens Networks GMBH & Co. KG and the Tyndall National Institute of University College Cork.

ORC Project Leader Professor David Richardson comments:

"We are close to realising the fundamental data carrying capacity limits of current fibre technology in the laboratory and although there is plenty of headroom for capacity scaling of commercial systems for the next 10-15 years, we need to be looking now at developing a new generation of transmission techniques based on novel fibres and amplifiers if we are to keep pace with society's ever increasing data transport demands in the longer term.

"The MODE-GAP project has the potential to revolutionise the way we build and operate future generations of optical network. Success will require substantial innovation and major technological developments in a number of fields. The consortium partners believe that they are ideally equipped to undertake the work and are looking forward to the many challenges ahead." Bart Van Caenegem, Project Officer at the European Commission, comments: "A European consortium of highly qualified and talented researchers has teamed up and has adopted a ground-breaking approach in R&D to advance the transmission technologies that will enable the networks of the future. This EU-funded project contributes to the Digital Agenda objectives, namely it aims to improve the competitiveness of the European industry and it aims to enable Europe to master and shape future developments in ICT so that it can meet the demands of its society and economy."
