PhD Semiconductor Laser Sources for Optical Coherence Tomography

TP-1 PHD Semiconductor Laser Sources for Optical Coherence Tomography

Contract Type:   Full-time

Tyndall National Institute at University College, Cork invites applications for a PhD in field of semiconductor laser sources for Optical Coherence Tomography (OCT) applications.

One PhD position is available in CAPPA group (Centre for Advanced Photonics & Process Analysis)  at the Tyndall National Institute under the supervision of Dr. Tomasz Piwonski. This is a funded position for up to 4 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, integration and demonstration of the technology and will work in a team with other research groups in Tyndall. The project is a collaborative project with industry.

Key Duties and Responsibilities

  • Review of state of the art (publications in journals, conferences and patents)
  • Design and simulations
  • Fabrication of semiconductor swept source lasers
  • Electro-optical characterization
  • Ability to write articles in journals/conferences
