Abstract

The research line "plasmonic devices in Graphene and coupling to photonic waveguides" of the SPEC project to which this fellowship is connected aims to excite plasmonic modes from optical waveguide modes, using metallic nanostructures as scatterers (see main projects text). To develop this line, it is important to study several waveguides in different geometries and materials, in order to determine the configuration that enables the most efficient opto­ plasmonic coupling. To study and optimize, for example, the energy contained in the evanescent portion of the field that superposes with the metallic nanostructures is crucial for a good coupling. This post­ doctoral fellowship aims to address these issues in order to enable the success of the research line. Overall, we intend to numerically and experimentally study different waveguides in order to maximize the coupling between the guided light and the nanostructures. Moreover, methods to transfer the graphene sheet to the waveguide will also be studied. The researcher will work in close proximity, and sometimes in an overlapped manner, with master and doctoral students.
