2013 Lalanne portrait

Philippe Lalanne (mail : ; tél. +33 5 57 01 72 01)

Philippe Lalanne is Directeur de Recherche at CNRS and is an international expert in nanoscale electrodynamics. He was first involved in Optical Information Processing in the group of Pierre Chavel at l'Institut d’Optique. In 1995, he spent a sabbatical year in the group of G.M. Morris, at the Institute of Optics in Rochester.

With his colleagues, he has launched new and powerful tools and models in computational electrodynamics [JOSAA 13 (1996), JOSAA 18 (2001), PRL 110 (2013)], has provided deep insight into the physical mechanisms involved in key nanoscale optical phenomena and devices, e.g.light confinement in photonic-crystal cavities [APL 78 (2001),Nature 429 (2004)] and the extraordinary optical transmission through metallic hole arrays [Nature 452 (2008) and Nature 492 (2012)], and has designed and demonstrated novel nanostructures with record or completely novel performance in their time, e.g. diffractive optical elements [J. Opt. A: Pure Appl. Opt. 4, S119 (2002)], slow light injectors [OL 32 (2007)], directional plasmon launchers [NL 11 (2011)], non-classical light source devices [PRL 105 (2010), Nat Photon. (2010)].

He has co-authored about 170 publications in peer-reviewed journals and filled 10 patents. He is a recipient of the Bronze medal of CNRS, the prix Fabry de Gramont of the Société Française d’Optique. He is a member of the editorial board of Advanced Optical Materials and Laser & Photonics Reviews, a board member of the OSA international council, Faculty advisor of the Bordeaux SPIE and OSA Student Chapter and is deputy-director of GDR ondes. He is a fellow of the IOP, OSA and SPIE and was Carl Zeiss visiting Professor at Jena in 2010

He was the supervisor of 12 PhD candidates, has co-supervised 5 PhD candidates. He is currently working on computational electrodynamics, slow light, quantum plasmonics, and transport in complex optical systems.


We offer postdoc, PhD, master positions in three areas. See
