PhD in “Advanced Digital Signal Processing Enabling Flexible Coherent PON

PMO-33 PhD in “Advanced Digital Signal Processing Enabling Flexible Coherent PON towards 200G/λ and Beyond”

Contract: Full Time/Fixed Term  

PIADS Centre for Doctoral Training PhD Studentships

We have a prestigious PIADS PhD position available in the Photonic Systems Group at Tyndall National Institute. The successful candidate will work under the supervision of Dr. Xing Ouyang and Prof. Paul Townsend. 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 at Tyndall National Institute, and registered as PhD student at University College Cork. 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 :Advanced Digital Signal Processing Enabling Flexible Coherent PON towards 200G/λ and Beyond.

Passive optical network (PON) is a vital fiber-optic technology that delivers ultra-high-speed Internet and data services to a range of end users— known as the Fiber-To-The-x (FTTx), where “x” stands for home, business premises, cellular sites, and so on — in a low-cost and effective way utilizing its unique point-to-multipoint (P2MP) network architecture. Due to the growth and sustainability of our modern society of tremendous magnitude, especially in the post-Pandemic world, our global networks are undergoing ever-increasing data traffic. The overarching aim of the project is to design the physical layer Digital Coherent PON technology as an enabling fabric of the succeeding evolution, and develop advanced DSP technologies for flexible PON transceiver as a converged design bridging the traditional IM/DD- and future DCO-based PON systems, and implement proof-of-concept demonstrations — in synergy with the advanced devices and packaged transceiver technologies of other IPIC themes — for the final showcase demo.

Key requirements

  • First or upper second-class honour’s degree (or equivalent international degree/master degree) in Electrical/Electronic Engineering, Physics, Communication Engineering, or a related relevant discipline.
  • Strong background in mathematics, statistics, digital signal processing, and communication system modelling.
  • Experience in signal processing and testbed for high-speed fibre-optic systems or other communication systems, such as wireless 4G/5G and WLAN systems.
  • The candidate must have knowledge and experience of one or more programming languages, such as MATLAB, C/C++, Python or equivalent.
  • The candidate must demonstrate proficiency in English alongside good scientific writing and communication skills and if possible, for example, with publications in high-impact IEEE/Optical journals and/or conference.

What we offer

A fully-funded PhD position that includes a stipend of €19,000/year for up to four years and full coverage of academic fees. The successful candidate will be registered as PhD student at University College Cork.

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 20th April, 2023.

Successful candidates may start their PhD position latest in September 2023.
