Biography: 

Professor Jean-Michel Nunzi, received his Ph.D. degree in Physics from Plasmon Nonlinear Optics, École Polytechnique (France) in 1984, and Ph.D. degree in Physics from Polymer Nonlinear Optics, Commissariat à l'Énergie Atomique in 1990. Now he is a full professor of Department of Physics, engineering Physics and Astronomy, Department of Chemistry, Queen’s University, Canada. Tier 1 Canada Research Chair in Photonics for Life. He is also the visiting scientists of our institute under the CAS President’s International Fellowship Initiative for 2017. His research interests are the optical and electronic properties of organic materials and devices, including photo-physics, nonlinear optics, self-organization under light, charge generation and transport, solar cells, plastic lasers, nano-materials, bio-compatible materials and devices. He also studies the fabrication of chiral structures using light - matter interactions. Up to now, he has published 11 patents, 240 peer-reviewed publications. More than 7000 citations, H-index is 44. He is SPIE Senior Membership, IOP Fellow, ACS National Membership, Member of the Optical Society of America, and Member of Chemical Institute of Canada and Constituent Societies. He also serves as Editorial Board Member of Scientific Reports, Chinese Optics Letters, European Physical Journal: Applied Physics, and Energies. 

Abstract: 

In this talk I will introduce optical nonlinearities on the basis of Maxwell equations, I then show some of the organic materials for NLO constantly in use in my lab. I introduce the origin of the susceptibilities on the basis of excited states and quantum mechanics. I then go to applications of which I selected light manipulation with light and 2nd harmonic generation. The idea is to deliver a unified picture of NLO and the possibility to easily enter new hot topics like cavity NLO and NLO-photovoltaics.
