CAPPA – Centre for Advanced Photonics & Process Analysis

The Centre for Advanced Photonics & Process Analysis (CAPPA) is a research centre of Cork Institute of Technology, conducting both applied and fundamental research on photonics for applications in areas as diverse as telecommunications, medical devices, food and pharmaceutical manufacturing. As part of the CIT@Tyndall partnership, several members of CAPPA are co-located in Tyndall National Institute, forming a group within Tyndall’s Photonics Centre.

CAPPA is led by Dr. Guillaume Huyet, who is also the Head of the Dept. of Physical Sciences at CIT. In Tyndall, CAPPA occupies three state-of-the-art labs, and major research strands include non-linear dynamics of lasers and ultrafast laser physics, and the understanding of the dynamics of novel semiconductor materials and devices.

Current research activities of CAPPA include:

  • Swept source lasers for Optical Coherence Tomography
  • Optical characterisation of semiconductor materials and devices (including ultrafast spectroscopy techniques such as Time-Resolved Photoluminescence and Pump-Probe Spectroscopy)
  • Design and implementation of photonic sensors, e.g. for medical device and process monitoring applications

Cork Institute of Technology and Tyndall National Institute have a long history of collaboration, which goes back well over two decades. The early collaborations were mostly on a peer-to-peer basis, but as the research activity of both institutions grew and matured, it became clear that the full advantage of collaborations could only be achieved through closer cooperation. Hence, a formal Memorandum of Understanding (MoU) was established between Tyndall and CIT. This was officially launched in September 2008 by then Minister for Science & Education, Batt O’Keeffe, when he unveiled a commemorative plaque. More recently, the renewal of the MoU was marked by a ceremony in June 2014 attended by Seán Sherlock, Minister for Research & Innovation.

CAPPA accounts for the majority of CIT researchers based on-site in Tyndall. The group maintains three state-of-the-art labs and office space in Tyndall, and collaborates closely with Tyndall on major projects such as the IPIC research centre and the PROMIS EU Marie Sklowdowska-Curie Network. Tyndall also has strong collaborations with other groups in CIT, such as the NIMBUS Centre in the areas of embedded systems and energy.
