Photonic Device Dynamics

Welcome to the Photonic Device Dynamics Group website

The Photonic Device Dynamics Group has been renamed CAPPA


All of our group's activities have now been brought together under the umbrella title of the Centre for Advanced Photonics & Process Analysis (CAPPA). This combines both the fundamental science and industry-focused research strands of the group, as well as consolidating activities based on the main CIT campus and within the Tyndall National Institute; in future, the group's activities in Tyndall will be referred to simply as CAPPA@Tyndall.
Consequently, the Photonic Device Dynamics name is being phased out. These webpages and links will be updated soon. Until then, please bear in mind that some of the information on these pages may be out of date.

The Photonic Device Dynamics Group was created in September 2006 when Dr. Guillaume Huyet joined the Department of Applied Physics and Instrumentation at the Cork Institute of Technology. The group emerged from the Optoelectronics & Non-Linear Dynamics group of University College Cork (now the Laser Physics Group), but remains a member of the Tyndall National Institute. We are based in the Institute's facilities at the Lee Maltings complex, next to the river Lee in the centre of Cork city. The group's research aims to advance the understanding of the dynamics of novel semiconductor materials and devices from both applied and fundamental viewpoints. Current areas of interest include the properties of quantum dot systems (principally InAs dots but also recently GaSb dots) and optical feedback and injection in semiconductor devices.

 Ph.D. and M.Sc. Positions Available

The PDD group has a number of places available for postgraduate students interested in pursuing either an M.Sc. or Ph.D. degree in photonics. If you are interested in applying for one of these positions, or simply want further information on them, please contact Guillaume Huyet for an informal discussion.


CAPPA - Centre for Advanced Photonics and Process Analysis

The PDD group is also strongly linked with CIT's Centre for Advanced Photonics & Process Analysis, or CAPPA, an industry-led applied research group working in the fields of optics and photonics, aiming to forge strong alliances between industry and academia at CIT.

PROPHET - Postgraduate Research on Photonics as an Enabling Technology

The Photonic Device Dynamics Group are coordinating the EU FP7 Marie Curie Initial Training Network, PROPHET, which brings together 16 European partners to train the next generation of photonics researchers. 14 Ph.D. students and 5 postdoctoral researchers will be trained over four years, in the wide spectrum of skills required for a multi-disciplinary, industry-focused career in photonics. These skills will be applied in four key application areas: mode-locked lasers for Communications applications, solar cells for Energy applications, gas sensing for Environment applications and fast tunable lasers for OCT in Life Science applications. See the project website for available vacancies.

AQUA-PULSE - Photocatalysis with UV LED Sources for Efficient Water Purification

The Photonic Device Dynamics Group (as CAPPA) are a partner in the EU Research for SMEs project, AQUA-PULSE, which aims to realise a low-power, low-maintenance water purification solution based on high brightness UV LEDs and a photocatalysis method. It brings together three European SMEs and three Research Providers.
