Figure 1

(a) Artistic illustration of the coupled WSe2 monolayer (1L) single-photon emitter and the Si3N4 waveguide. (b) Finite element method eigenmode simulation of the fundamental quasi-TE and (c) quasi-TM waveguide modes at 770 nm wavelength. (d) Microscope image of the Si3N4 waveguide with (e) zoom-in of the WSe2 flake. The monolayer is marked in red (1L). (f) Photoluminescence with defocused excitation shows strain-localized emitters along the waveguide edges. Emitter 1 is marked with a red circle.
