Projekt se týká oblasti hybridních dielektricko-plazmonických vlnovodů a zaměří se na výzkum vazby mezi plazmonickými mody, které se mohou šířit na páscích grafenu, a vlnovodným modem. V rámci projektu plánujeme návrh a vývoj vhodných fyzikálních modelů vazby a experimentální charakterizaci vybraných hybridních vlnovodů s grafenem.

Popis anglicky
- Investigation of the resonant coupling between graphene SPs and a waveguide mode in promising hybrid nanophotonic waveguide structures - Exploring application of the effect for control of light with potentially useful advanced functionalities. - This will include development of the adequate physical models, numerical simulations and experimental characterization of selected DWGs, and first steps towards possible experimental confirmation of the effect. Theoretical studies, which will be coordinated by the Czech project partner (IPE), will rely on their expertise in modal techniques that are very efficient in description of coupled systems. We plan to develop a new formulation describing the waveguide-graphene interactions. These results will be supported with rigorous simulation tools (COMSOL). With regard to the experimental goals, the French project partner (IEMN) will bring its recently developed original expertise in near-field microscopy at THz and MIR frequencies using a scanning nanotip-scattering approach. This an original and entirely novel approach to characterize such hybrid waveguide-graphene polariton excitations. Besides bringing extra experimental information on the phenomenon under study by nanoresolved imaging of the graphene excitations, it also contributes in general to the currently heavily investigated domain of THz and MIR nanoscopy. A strong engagement of PhD students and junior scientists and direct application of results in education is also envisaged.
