Présentation

Kevin Heggarty is Professor in the Optics Department of the IMT Atlantique, a French “Grande Ecole” (graduate engineering school). His research interests include non-display applications of spatial light modulators and especially the design and fabrication of diffractive micro-optical elements and their applications in photonics, optical information processing and optical telecommunications. He has published over 80 papers and patents in international reviews and conferences, ran or participated in several European projects, numerous industrial and French national (ANR) projects and is a founder of the spin-off company Holotetrics.

He has teaches optics/photonics/electro-magnetism at all levels at the IMT Atlantique and has lectured in Masters courses in France, Spain, Germany and Belgium, He received his B.A. in Natural Sciences from the University of Cambridge (UK) in 1987, an M.Sc. in Telecommunications and Information Systems from the university of Essex (UK) in 1988, his doctorate from the Ecole Nationale Supérieure des Télécommunications (E.N.S.T.) in Paris (FRANCE) in 1991 and his Habilitation à Diriger des Recherches (HDR) in 2010.
