Over the past decade, there is a growing research activity on light-matter interactions in atomically thin materials, such as graphene, topological insulators, thin polar and semiconducting layers and other van der Waals materials, including their heterostructures. Here, we will consider 2D ("flatland") materials as a promising rich platform for manipulation of infrared (IR) and terahertz (THz) waves. We will show how to launch and focus polaritons in graphene sheets and nano-cavities [1,2] and thin van der Waals multilayers (BN and graphene-BN hybrids) [3]. We will discuss both theoretical and experimental studies on 2D optics (optics in atomically-thick layers) as well as the applications of 2D plasmonics to modern IR and THz sensing and photodetecting optoelectronic nanodevices (see Fig.). Artistic representation of the concept of on-chip merging graphene photonics and electronics [3].

Dr. Alexey Nikitin is an expert in theory of electromagnetic wave phenomena, particularly in nanophotonics. Recently, his main scope of interest has been light-matter interaction in low-dimensional systems (such as graphene, topological insulators, BN and other van der Waals materials). He obtained his PhD in theoretical physics in 2005 in the Institute for Radiophysics and Electronics (Kharkov, Ukraine). Starting from 2006 he had a postdoctroral stay in the University of Zaragoza (Spain) being awarded with two individual grants for talented young scientists: INTAS (sponsored by European Union) and Juan de la Cierva (sponsored by Spanish Ministry of Science). In 2013 he joined nanoGUNE research centre as an Ikerbasque Fellow.
