On the subject:

Light-matter strong coupling and potential for chemistry and biology

When matter is placed in the confined field of electromagnetic radiation, it can lead to modified and even new properties. This is of great interest from both the fundamental point of view as well as for many radiation engineering applications. For instance, the field confinement can lead to effects such as extraordinary optical transmission, enhanced absorption and emission of light, high-resolution spectroscopy and imaging. Under certain conditions, the light-matter interaction can become so strong that it enters the so-called strong coupling regime where new hybrid light-matter states are formed, offering a vast potential for chemistry and biology that has hardly been explored.

In this talk, I'll present the nature of enhanced optical phenomena using nanophotonics and plasmonic structures, emphasizing the applications of harnessing radiation fields into confined regions for bio-sensing and molecular detection. Then, a basic introduction to strong coupling of optically-active substances will be presented. Strong coupling of molecular vibrational transitions in the infra-red region will be particularly elaborated with new prospects to modify molecular and structural processes. New directions for exploiting strong light-matter interactions for bio-sensing and biomedical applications will be discussed.

Short biography:

Dr. Shalabney graduated from the Electrical Engineering Department of the Technion in 1997. He received his M.Sc. and Ph.D. degrees from the Electro-Optics Engineering Department at the Ben-Gurion University in the years 2010 and 2013 respectively. During his Ph.D., he worked within the group of Prof. Ibrahim Abdulhalim on developing plasmonic nanostructures to enhance the sensitivity of optical bio-sensors. In 2013, Dr. Shalabney joined the group of Prof. Thomas  Ebbesen at the University of Strasbourg, where his work has been focused on light-matter strong coupling with applications in biology and chemistry.
