Dr. Julien CARDIN (CIMAP), 40, Habilitation research the University of Caen Lower Normandy (2015) and PhD in Solid state physics (high honors with congratulations of the jury) of the University of Nantes (2004).

The thesis work has carried on the development and characterization of thin films ferroelectric perovskite PZT for optical applications to the former Institute for Research in Electricity Electronics Nantes Atlantique IREENA (currently the antenna Nantes IETR).
In his thesis, he has a unique contribution to the development of prism spectroscopy technique (M-lines) through the determination of optical losses and the analysis of two and three-layer system.
In 2005, he joined the Royal Institute of Technology (KTH) in Stockholm (Sweden) in the laboratory of Photonics and Microwave (MAP IMF) on a postdoctoral 2 year contract.
Under the direction of Professor Bozena Jaskorzynska, this work has carried on the development of hybrid photonic crystals based application photonic silicon / silica and electro-optic polymer materials. He achieved numerical modeling waveguide hybrid silicon / silica / polymer tunable directional coupler wavelength and development of deposits of organic electro-optic materials.
In 2007, he joined the CIPAC laboratory at the University of Caen, where he develops optical materials spectroscopic characterizations such as silica enriched silicon, Ga2O3, HfO2 or the ZnO, these materials are doped with ions rare earth (erbium, neodymium, ytterbium ...) and dielectric composite media / metal plasmon resonance.

More recently, he develops methods of optical modeling of light-matter interactions in different configurations reflecting the applications referred to CIPAC laboratory. These modeling methods (ADE-FDTD, optical matrix, discrete dipole approximation ...) are applied to the study of devices such as optical wave-based rare earth material and silicon amplifier nanograins guide, study deformed metal metallic nanoparticles by irradiation and thin Films for frequency conversion for photovoltaics.

Julien Cardin is the co-author of 60 papers (articles, documents ..) he produced 15 national and international oral conference and participated in over 10 national and international research projects.
