TP-2 Postdoctoral researcher position in Photonics

Job title:  Postdoctoral researcher 

Contract: Full-time / Fixed Term

Job description

Tyndall National Institute at University College, Cork invites applications for postdoctoral researcher position in the field of semiconductor laser sources for Optical Coherence Tomography (OCT) applications. The successful candidate will join CAPPA group (Centre for Advanced Photonics & Process Analysis) ( at the Tyndall National Institute to work under the supervision of Dr. Tomasz Piwonski. This is a funded position for up to 2 years.

The aim of this project is to develop new continuous wavelength tuned (swept sources) semiconductor lasers sources at 850 nm for OCT applications. Such lasers will provide an important breakthrough providing a platform that will enable cutting edge research in biomedical imaging and industrial metrology applications.

Optical coherence tomography (OCT) is an imaging technique which enables the acquisition of real-time, high-resolution cross sections of scattering media. It is best known for delivering images of biological tissues however its areas of applications is growing and now includes e.g. nondestructive material testing. The core element of this technique is a light source whose properties directly affect quality of acquired images. The aim of this project it to utilize advanced optical techniques to develop and improve performance of semiconductor lasers source used in OCT thus allowing new application areas to be realised on the back of improved device performance.  The researcher will be involved in the design, development, fabrication and integration of the technology and will work in a team with other research groups in Tyndall. The project is a collaborative project with industry.

Key Responsibilities

  • Design and simulations of semiconductor photonic devices using commercial software
  • Fabrication of semiconductor swept source lasers.
  • Electro-optical characterization.
  • Review of state of the art (publications in journals, conferences and patents)
  • Contribute to grant proposal writing for EU and other funding streams.
  • Engage in the dissemination of the results of the research. Ability to write articles in journals and attend conferences
  • Participate in Education and Public Engagement activities, as required.
  • Ensure all activities are compliant with the Tyndall Quality Management system.
  • Ensure all activities are compliant with the required Health and Safety standards.

Essential Criteria

  • The post will require a researcher who holds a PhD in a relevant field such as physics, photonics, optoelectronics or a related discipline.
  • Strong theoretical and experimental skills and hands-on experience with fabrication and characterization of photonic semiconductor devices (lasers, amplifiers etc.) are essential.
  • Broad experience in optical spectroscopy.
  • The candidate must demonstrate an academic record of scientific excellence, independent research.
  • Experience in programming and communication with laboratory instruments (C++, MatLab, LabView or similar)
  • Good communication, writing, organization and interpersonal skills.
  • Highly self-motivated and able to demonstrate initiative.
  • A capability of working within a project team to achieve results.
  • A commitment to personal development.

Desirable Criteria

  • Design of optical systems using commercial software (Fimmwave, Lumerical etc.)
  • Designing of photolithography masks.
  • Operation and programming of microcontrollers
  • Fast prototyping (CAD, SketchUp, 3D printing…)
