Biographical sketch of Jean-Louis de Bougrenet de la Tocnaye :
Head of the Optics Department, Telecom Bretagne.
 
Academic cursus : PhD in Optics (1981) Marseille University, licencié ès Lettres (1984) Aix-Marseille University, Doctor ès Sciences (1985) Marseille University.
 
Scientifical skills: Field of expertise covers: optical signal processing diffraction theory (vortex, axicon, diffractive optics), interferometry and optical properties of liquid crystals with applications in telecoms and optics. World expert in this field, member of several technical committees of international conferences, chairman of the FLC conference and their applications in 1997, he contributed to elaborate the self-imaging theory with applications in optics and telecommunications, stating the 3D self-imaging conditions and analytical expressions for the diffraction of Gaussian beam gratings, with applications in optical communications. He is at the origin of new concepts for dynamic spectral equalizers and wavelength blockers based on normal quantile law, he introduced into optics, as well as the design and manufacturing of fast polarization controllers for PMD compensation. He demonstrated the first tunable VCSEL and cholesteric photonic liquid crystal, both devices based on polymer stabilized liquid crystal technology. Recently, his skills have been applied to new kinds of optical shutters for welding masks and stereo-goggles for 3D cinema. In particular he investigated achromatic large viewing angle active glasses using thin liquid crystal technology as well as chromatic properties of annular linear diffractive axicons for colour splitter/combiner. His attention is focused at the moment on 3D acceptance and ophthalmic and neuro-ophthalmic impacts.
 
Scientific production : Author and co-author of more than 130 papers in international refereed technical journals as well in conference proceedings, author and co-author of 47 patents.
