The on-chip integration of quantum light sources and nonlinear elements constitutes a major step toward scalable photon-based information processing communication. In this work we demonstrate the potential hybrid technology that combines organic-molecule-based emitters dielectric chips consisting ridge waveguides grating far-field couplers. particular, dibenzoterrylene molecules in thin anthracene crystals are used as single-photon sources, exhibiting long-term photostability, easy fabrication methods, almost unitary yield, lifetime-limited emission at cryogenic temperatures. We couple such single to silicon nitride waveguides, showing coupling efficiency up 42 ± 2% over both propagation directions. Our results open novel path fully integrated photon-processing platform.
