Two-dimensional materials like Transition Metal Dichalcogenides (TMDs) have shown exceptional promise for on-demand solid state single-photon emitters in which strain enables site-selective, localized quantum emitter formation. It is viable to integrate these within photonic structures such as waveguides using pick-and-place methods. In our study, we demonstrate quantum emission in monolayer WSe2 deposited onto horizontally aligned InP nanowire waveguides (NWs). The faceted nature of NWs renders control in tailoring the strain-induced QE locations relative to the traditional rectangular waveguide geometries by the potential orientation of QEs on the top surface for efficient coupling. Multiple bright and narrow emission peaks are observed in the 715-785 nm spectral range, along with g(2)(0) as low as 0.049, indicative of high purity single photon generation.
