Research overview

Liam O'Faolain is a lecturer at the School of Physics and Astronomy at the University of St Andrews. He is one of the leading authorities on disorder and loss in Photonic Crystals and has  designed  and  realised  the  world's  best  slowlight  waveguides  to  date. Photonic crystal cavities are another of his main research interests, and he has recently used them to realise record low optical switching energies and record high levels of light emission from silicon. One of his group's main research goals is the realisation of a new family of low power optical interconnects based on Photonic Crystal cavities.

He also co-founded and runs NanoPIX, a foundry service for nanophotonic devices ( This has supplied  15-20  research  teams  across  Europe  with  bespoke  samples,  resulting  in  more  than  80  joint publications since September 2006.

He is PI on the Scottish Enterprise Proof of Concept project FRONTIER which is commercialising some of his recent discoveries.
