Abstract Scalable, reliable quantum light sources are essential for increasing quantum channel capacity and advancing quantum protocols based on photonic qubits. Although recent developments in solid‐state quantum emitters have enabled the generation of single photons with high performance, the scalable integration of multiple quantum light sources onto practical optical platforms remains a challenging task. Here, a breakthrough in achieving a multiple, tunable array of quantum photonic devices is presented. An individual device transfer process allows post‐characterization and selective integration of multiple single‐photon sources onto a V‐groove fiber platform. The nanophotonic cavity ensures efficient coupling of single photons into a standard SMF 28 fiber. Moreover, applying an electric field enables a frequency shift of the integrated single‐photon device. Therefore, the fiber‐integrated quantum platform realizes a scalable and reliable single‐photon array within a compact fiber chip at telecom wavelengths.
