Coupling single photons from discrete quantum emitters in WSe${}_2$ to lithographically defined plasmonic slot-waveguides

Mäx Blauth, Marius Jürgensen, Gwenaëlle Vest +5

We report the observation of the generation and routing of single plasmons generated by localized excitons in a WSe${}_2$ monolayer flake exfoliated onto lithographically defined Au-…
