PMO-36 PIADS: PhD in analogue RoF and digital transmission coexistence- Dublin

PIADS Centre for Doctoral Training PhD Studentships

Contract: Full Time/Fixed Term

Project title: Coexistence of digital and analogue optical transmission over converged access/metro architectures through intelligent control plane and signal adaptation

We have a prestigious PIADS PhD position available in the Optical Network Architecture group at Trinity College Dublin, under supervision of Prof. Marco Ruffini and co-supervision of Prof. Liam Barry at Dublin City University.

Students will join an exciting and well-established Centre for Doctoral Training (CDT) hosted by IPIC (the Irish Photonics Integration Centre) in the Republic of Ireland (ROI), and in partnership with Queens University Belfast and the University of Glasgow. You will be based in Dublin, and registered as PhD student at Trinity College Dublin. You will have access to an advanced structured training programme, to world class facilities and academic expertise that spans the partners in IPIC as well as the University of Glasgow and Queen's University in Belfast.

Project details

Novel optical access and metro networks are essential to support fast growing capacity requirement, driven by novel 5G and 6G networked applications. Flexibility is an essential feature, driven by novel reconfigurable components. These however require the development of intelligent control planes to autonomously manage network requests, maintaining high availability and optimal resource utilization.

One PhD studentship is available for work in the area of optical communications in support of 6G networks. This research will explore how optical access and metro networks can support next generation 6G services. More specifically, it will investigate novel transmission systems, mostly based on Radio-over-Fibre to support the higher capacity requirements, but over highly heterogeneous network architectures. A key investigation will be the coexistence of RoF signals across access and metro networks. Indeed, in order to provide ubiquitous, flexible access, at low cost (which is necessary to enable densification) the high-capacity RoF signals will need to be routed across a highly heterogeneous network, which could consist of standard PONs, enhanced mesh-PON architectures, filter-less node architectures and transparent integration with metro networks. The scenario is also highly dynamic owing to its dependency not only on overall network load from multiple applications, but also on the load on edge computing nodes (which are inherently small and thus will have higher fluctuation in load) as well as new applications.

This requires:

  • Investigation of adaptive, flexible approaches for uplink and downlink signal transmission, including analog and digital waveforms, modulation and coding supporting both photonic-enabled mmWave and THz wireless services;
  • Investigation of control plane estimation and decision algorithms, including Quality of Transmission estimation, for coexisting digital and analogue RoF signals, and decision making on optimal signal routing strategy and wavelength band to use.
  • The position will be based both in Trinity College Dublin and Dublin City University.

    The position will be under the direction of Prof. Marco Ruffini and Prof. Liam Barry


    The candidate must have a Bachelor degree (Master preferred) in Electrical Engineering, Computer Engineering, Physics, Computer Science, or a related field, with a minimum mark of 2.1 (i.e. with a score higher than 60%). First class honour (mark higher than 70% is desired). The successful candidate will join a team of highly skilled and innovative researchers in next generation wireless and optical networks.

    Essential Criteria

  • Knowledge of machine learning theory and algorithms.
  • Knowledge of optical transmission systems
  • Knowledge of networking both at physical layer and protocols (layer2/layer3).
  • Working knowledge of python programming language and Linux operating system
  • Excellent written and oral communication skills
  • The ability to work well in a group.
  • Strong self motivation and willing to learn attitude
  • Desirable Criteria

  • Experience with network-oriented programming.
  • Interest in one of more of the following areas: software defined radio, open optical systems, software defined networks control plane, virtualisation and orchestration.
  • Working knowledge of programming languages such as c++, java.
  • What we offer: A fully-funded PhD position that includes a stipend of €18,500/year for up to four years and full coverage of academic fees.

    Why Apply?

    As a student on the programme you will join a vibrant, supportive and engaging cohort of over 40 students and will have the chance to travel and attend a bespoke week long induction programme with students from all three partners, an annual Winter & Summer School and have access to advanced training courses in areas such as semiconductor fabrication, packaging, biophotonics and entrepreneurship. In addition, IPIC and PIADS have many industry partners that will open up many research and career opportunities.

    Graduating PIADS doctoral students are equipped with the highest level of scientific and engineering research skills needed to address the challenges of developing new integrated photonic technologies for diverse applications, as well as with the entrepreneurial, leadership and teamwork capabilities needed to lead and operate at the highest levels in industry. The programme is a gateway to a vast array of career paths from data storage, semiconductors, telecommunications, biophotonics, medical technologies and more.

    Closing date for application is 28th February 2023. Successful candidates may start their PhD position latest in September 2023.

    For any informal queries, please contact Prof Marco Ruffini marco.ruffini@tcd.ie or Elisabeth Wintersteller at elisabeth.wintersteller@tyndall.ie.
