Leader in Integrated ICT Hardware & Systems


Professor Peter O’Brien received his PhD in physics from University College Cork (Ireland) in 1999. He was a postdoctoral scholar at the California Institute of Technology (US) and NASA’s Jet Propulsion Laboratory (US). In 2006, he founded Epi-Light Ltd. – a photonics company developing specialty optical systems for medical device and bio-imaging applications – selling the company in 2009, and returning to Tyndall to establish an advanced photonic packaging and integration group. Today, the group has grown to 20 researchers, and is involved in a wide range of academic and industry-funded projects, with a special focus on packaging and integration for silicon-photonics devices. Prof. O’Brien works to develop photonic packaging standards and to support photonic-packaging for the ePIXfab and EuroPractice silicon-photonic foundries. He is deputy director of IPIC – the Irish Photonic Integration Centre ( – that recently received €30M of funding from Science Foundation Ireland.
