Integrated quantum photonic circuitry is an emerging topic that requires efficient coupling of quantum light sources to waveguides and optical resonators. So far, great effort is devoted to engineering on-chip systems from 3D crystals such as diamond or gallium arsenide. In this study, room-temperature coupling is demonstrated of quantum emitters embedded in layered hexagonal boron nitride to an on-chip aluminum nitride waveguide. 1.35% light coupling efficiency is achieved in the device and transmission of single photons through the waveguide is demonstrated. The results serve as foundation for integrating layered materials to on-chip components and realizing integrated quantum photonic cir..
