Strong light-matter coupling in atomically-thin excitonic semiconductors (Conference Presentation)
Author(s): Deep Jariwala

Paper Abstract

I will present our recent works on confining visible frequency photons in heterostructures for plasmonic metals and excitonic transition metal dichalcogenides (TMDCs) of Mo and W. Evidence of strongly coupling between excitonic modes and Fabry-Perot like resonances will be presented in unpatterned case. When the TMDC layer is patterned, plasmonic and dielectric grating modes emerge which lead to further coupling with excitonic modes resulting in tunable strong coupling and light confiementment. Finally, I will extend this notion to monolayer TMDCs and show evidence of near-unity absorption in metamaterials of the same for applications ranging from optical modulators to photodetectors and photovoltaics.
