Biography

Dr Luca Sapienza is a Reader in Quantum Technologies at the James Watt School of Engineering and he is a member of the Centre for Quantum Technology of the University of Glasgow.

He is leading the Integrated Quantum Photonics research group whose activities focus on the fundamental understanding of quantum optics effects on a chip, the development of quantum and nano-photonic devices integrating single-photon emitters and the study of quantum effects in bio-molecules. 
Research activities span electromagnetic simulation, nanofabrication and optical characterisation, by means of time-resolved micro-photoluminescence spectroscopy, down to cryogenic temperatures.
Device technology is based on III-V, silicon, silicon nitride and hybrid material systems to realise photonic crystal and plasmonic waveguides, optical cavities and resonators.

Prior to joining the University of Glasgow, Luca was an Associate Professor of Physics at the University of Southampton (United Kingdom) and he has held visiting positions at the National Institute of Standards and Technology (USA) and at the Ecole Normale Superieure de Paris (France).
