Silicon based materials are widely used for photonic integrated circuits (PICs), because of their low losses in the telecom wavelength regime and available manufacturing expertise. These properties makes them suitable for potential large scale PICs for on-chip quantum technologies. On demand single-photon sources are hard to realize in these systems, due to the indirect bandgap of silicon. On the other hand, InGaAs Quantum Dots (QDs) can emit high quality single photons at telecom wavelengths making it desirable to combine both material platforms. Here we discuss our first steps in combining the benefits of III-V QDs and SiN photonic chips.
