Periodic Reporting for period 1 - FIWIN5G (FIber-Wireless Integrated Networks for 5th Generation delivery.)

Teaser

Summary

This Innovative Training Network aims to produce the next generation of early stage researchers (ESRs) who will enable Europe to take a leading role in the development of future devices, systems and networks supporting the 5G high-speed wireless internet. As the MSCA programme strives for excellence, the consortium made an effort to select the best ESRs from the 482 applications received. All the Beneficiaries are concerned about the high quality of the FiWiN5G network and overall success of the project. In order to achieve best results and match the MSCA ITN requirements, the consortium ensured that the ESRs are working in interdisciplinary teams, integrate their activities, share expertise, and promote a vision of a converged wireless and optical devices and networks that efficiently supports the services and applications. While becoming experts in one particular sub-domain, the ESRs must understand the broad context of their work, whether it is systems/network engineers understanding the devices and technologies that make up the networks or device engineers understanding the networks in which their devices will function. We draw together a range of world-leading partners, selected for their complimentary and excellence to offer a vital opportunity to advance industryâ€™s understanding and uptake of the key technologies in this area.

Work performed

The main actions of the programme so far have been to recruit the full cohort of ESRs and implement the training programme. As of April 2016, the full cohort of 15 ESRs have been recruited to the network. The project has put on a number of training events for the ESRs and to publicise the network. The first Summer School was held in London on the 30th June 2015 in association with the 20th European Conference on Network and Optical Communications. The first winter school was held in conjunction with the IEEE International Topical Meeting on Microwave Photonics during the week of 26 â€“ 29 October 2015 in Paphos, Cyprus. The 2nd Summer School was held in Copenhagen on the 24th and 25th May 2016 while the 2nd Winter School was held in Ljubljana from the 2nd to 7th February 2017. These summer and winter schools provide specific training for the ESRs as well as allowing the exchange of ideas between ESR projects.

A number of bespoke training opportunities have also been offered to ESRs in both technical and transferable skills. These have including training courses on Photonic Integrated Circuit Design for Millimetre and Terahertz Wave Generation, theory and modelling of key photonic devices, practical skills in the fabrication of III/V semiconductor based key photonic components, RF and Optical Measurement techniques, knowledge creation and Organisational Design, People Management and Innovation.

Final results

Most of the ESR projects are still at a relatively early stage of development. However, some important results with high potential impact have already immerged.

One project has produced a novel InP UTC photodiode array on Si wafer with high responsivity and bandwidth which will enable highly integrated and steerable antennas for high frequency 5G applications. Another project has produced and tested a design for a photonic integrated circuit capable of producing a Pulse train and optical comb at 75 GHz (fundamental repetition rate), 150 GHz (1st stage post-processed) and 300 GHz (2nd stage post-processed). Across the projects a number of fundamental advices in photonic device technology, such as these, are expected. These novel and innovative technologies will support higher bandwidth optical backhaul and fronthaul systems and support the evolution to millimetre wave frequencies predicted to be a central part of 5G techniques.

In parallel to device technologies, ESRs are researching data communication techniques to support the high bandwidth 5G communication systems. Others are working to design and implement system experiments, potentially involving the components developed in the project, to demonstrate the applicability and impact of FiWiN5G technologies.
