Philippe Lalanne, email : email@example.com ;
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), JOSAA 22 (2005), 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), Nature 492 (2012)], and has designed and demonstrated novel nanostructures with record or completely novel performance in their time, e.g. diffractive optical elements [Opt. Lett. 23 (1998), JOSAA 16 (1999)], slow light injectors [Opt. Lett. 32 (2007)], directional plasmon launchers [NanoLett 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 Chapters 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 15 PhD candidates, has co-supervised 5 PhD candidates. He is currently working on computational electrodynamics, slow light, quantum plasmonics, and complex optical systems.
RETOP implements near-to-far-field transform (NFFT) for light scattering or emission problems in stratified media. RETOP can be used to retrieve the free-space and/or guided-mode radiation diagrams. The NFFT relies on the knowledge of the near-zone field (obtained from any full-wave Maxwell’s solver, not provided) on a rectangular box that should fully surround the local inhomogeneity. It is especially relevant for calculating the scattering of nanoparticle on substrates. Special attention is made to the interface with COMSOL Multiphysics.
QNM calculates and normalizes (mode volume) the resonance mode (also known as the quasi-normal modes or QNMs) of plasmonic or photonic nano/micro resonators. It relies on pedagocical Matlab programs that operates under Matlab-COMSOL livelink. A toolbox also calculates the absorption/extincsion cross-sections and the calculated normalized QNMs can be directly used to calculate LDOS (or Purcell factors).
RETICOLO implements the rigorous coupled wave analysis (RCWA) for 1D (classical and conical diffraction) and 2D crossed gratings. It operates under a MATLAB environment and incorporates an efficient and accurate toolbox for visualizing the electromagnetic field in the grating.
We offer postdoc, PhD, master positions in three areas:
We are currently looking for a motivated PhD student to work on the "Exotic optical properties of complex plasmonic nanostructures". See description here:
We also have an open position for a M2 internship on the "experimental characterization of light scattering by metasurfaces". See description here:
Researchers at LP2N have revealed and explained the importance of the effective photon mass in the formation of Anderson highly-localized states in periodic waveguides.
Researchers at LP2N have elaborated a freeware to compute the free-space and guided radiation diagrams of objects embedded in thin-film stacks.
