The Photonics Systems and Sensing Lab. (PSSL)

This is a research group that focuses on the simulation and demonstration of novel technologies
for future photonic systems. The research carried out in this group encompasses a wide array of
domains, including optical communications systems, a wide array of high-speed semiconductor
devices, optical transmitters and receivers, optical pulse and frequency comb sources, high speed
detection, photonic sensing as well as optical and digital signal processing. PSSL has strong
linkages with academic and industrial partners in Ireland and abroad and works on a mix of
fundamental and applied research topics in the domains of radio and optical systems.

The Project - Intelligent Photonic Sensor System (InPhoSS)

This research project is in the area of photonic sensor/interrogator technology for the development
of a high-resolution real-time sensing solution. The InPhoSS project is funded by Enterprise Ireland
(EI) through a Commercialisation Fund (CF).

Photonic based sensing technology has garnered a lot of attention recently as an effective tool for
a wide range of applications such as monitoring low-level gas emissions, LIDAR and assessing
and monitoring of civil infrastructures, etc. Taking gas sensing as a typical use case, individual
gases possess absorption coefficients at unique frequencies and when a light source is passed
through a sample, it's possible to identify the gas by its absorption profile. In this project, an
intelligent photonic sensor system is proposed. This system will consist of an interrogator based on
a dual optical frequency comb approach developed in CF-2017-0683A-P “INDOTS” and an
intelligent receiver based on artificial neural networks.

Role Profile

The successful candidate will play a substantial role in the design and development of an intelligent
neural network receiver implemented on an FPGA which can investigate spectroscopic data
emanating from a photonic interrogator. The characterization of the system for differentiating
between various absorption levels will be a vital aspect to be explored in this project. The work will
also examine how to benchmark the system utilising more conventional interrogator/receiver
approaches and illustrate the performance of the prototype for use in real world scenarios. The
role will provide access to competent technical, infrastructural and administrative assistance and
the opportunity to evolve a multi-facetted skillset in an environment where you closely partner with
world-class Irish and international companies and research organisations. One of the highlights of
working on such a project is that there is a strong potential of the outcomes being commercialised,
which may direct to exciting/rewarding career opportunities.

Duties and Responsibilities

The Research Assistant will:
  • Conduct a specified programme of research within the InPhoSS Enterprise Ireland
Commercialisation Fund Project under the supervision of the project Principal Investigator.
  • Work closely with the Principal Investigator to develop a hardware based neural network
for analysis of spectroscopic data.
  • Attend and contribute to PSSL group meetings.
  • Carry out administrative work associated with the programme as necessary.
  • Engage in the dissemination of the results of the research in which they are engaged, as
directed by, with the assistance of and under the supervision of the Principal Investigator.
  • Participate in meetings with the interested parties (e.g. end-users, commercialisation
consultants, external industry and academic partners) and assist in promoting the
technology (e.g. conferences and tradeshows).

Qualifications, Skills and Experience:

Applicants must hold a primary degree (NFQ Level 8), MSc or Bachelor's Degree in Electronic,
Mechanical or Mechatronic Engineering or a cognate discipline.

Candidates will possess:
  • A passion for on-the-job learning and a willingness to contribute to multi-disciplinary
aspects of the project such as working with a photonic interrogator for spectroscopy and
contributing to the assembly and testing of an FPGA based prototype receiver.
  • Excellent written and verbal communication and social skills.
  • Proven ability to prioritise workload and work to strict deadlines.
  • Ability to work in a team and to take responsibility to contribute to the overall success of
the team.
  • Strong problem solving abilities.
  • Experience in FPGA programming and electronic hardware such as analog-to-digital
convertors, electrical spectrum analysers, and FPGAs along with microcontroller
programming is desirable.
  • An aptitude for hands-on work and comfortability in a laboratory environment.
  • A commitment to gaining practical experience working on a commercialisation fund.
Desirable
  • Digital signal processing
  • Neural networks
  • Spectroscopy
