Title: Metallic gratings covered with 2D materials: a route to polaritonics

Session Abstract

Metallic diffraction gratings have been intensively studied for more than a century. Its theoretical study started with the work of A. Sommerfeld back to 1899. The interest in metallic gratings was kept alive for many decades to follow with the work of U. Fano and A. Maradudin extensively contributing to its understanding. The latter author contributed with a number several works to the understanding of metallic gratings taking roughness into account. By the 1980’s, gratings were considered understood and the topic faded away. Coming from a completely different area of physics, the discovery of 2D materials around 2004-2005 gave rise to a new field of research in nanophotonics based on these new types of systems. Scientists regain interest in gratings when these are covered with 2D materials. This new type of system supports new types of polaritons whose study is still in its infancy. In this lecture we will present an ongoing theoretical study of a metallic grating covered with two types of 2D materials, an insulator, and a conductor. We will see the emergence of new types of polaritons with far reaching consequences in applications to sensing and nanophotonics.
