Emmanuel Rosencher  was born in Paris, France, in 1952. He graduated from the Ecole Polytechnique, Paris, France, in 1975 and from the Ecole Nationale Supérieure des Télécommunications, Paris, France in 1977. He received the Doctorat in Applied Mathematics from the Université de Paris IX in 1978 and the Habilitation Degree in Physics from the Université de Grenoble in 1986 From 1978 to 1988, he worked at the Centre National d’Etudes des Télécommunications (CNET) in Grenoble. In 1984, he discovered the transistor effect in the monolithic Si/CoSi2/Si heterostructure and studied the related Metal Base Transistor devices as well as the quantum transport in ultra-thin epitaxial metal film until 1988. In 1988, he joined the Laboratoire Central de Recherches de THOMSON-CSF in Orsay, France as the head of the Physics laboratory. In 1989, he discovered the giant optical nonlinear effects in asymmetrical quantum wells. In 1998, he joined the Office National d’Etudes et des Recherches Aerospatiales (ONERA), where he is currently the Director of the Physics Branch (420 persons).  He is a pioneer in the Physics of intersubband transitions in semiconductor quantum wells, optical non linearities in semiconductors and optical parametric oscillators. He received the 1991 Prix Foucault (Physique Appliquée) from the Société Française de Physique, the Montgolfier Award 2000 (Arts Physiques) from the Société d'Encouragement de l'Industrie Nationale, the 2001 Arnulf-Françon Prize from the Société Française d'Optique, the 2003 Grand Prix de Physique Appliquée from the Société Française de Physique and he is Chevalier de l'Ordre National du Mérite. Dr Rosencher has published more than 250 papers in the field of semiconductor heterostructures , nonlinear optics and laser physics with 140 papers in refereed international reviews and 70 invited talks. He also holds 21 patents. He is Fellow of the Optical Society of America (OSA), of the IEE and of the Institute of Physics (IoPF96), member of the French and American Physics Societies. He is Professor of Physics at the Ecole Polytechnique and writes also physics textbooks (Optoelectronics, Cambridge University Press in French, English and Russian) as well as books for the popularization of Science (La Puce et l’Ordinateur, Flammarion, translated in Italian, Spanish, Portuguese,…).
