Solid-state quantum light sources based on semiconductor dots (QDs) are increasingly employed in photonic information applications. Especially when moving towards real-world scenarios outside shielded lab environments, the efficient and robust coupling of nanophotonic devices to single-mode optical fibers offers substantial advantage by enabling "plug-and-play" operation. In this work we present a fiber-pigtailed cavity-enhanced source flying qubits emitting single indistinguishable photons at clock-rates exceeding 1 GHz. This is achieved employing fully deterministic technique for fiber-pigtailing optimized QD-devices hybrid circular Bragg grating (hCBG) micro-cavities. The fabricated hCBGs feature emission lifetimes <80 ps, corresponding Purcell factor ∼9, suppression multi-photon events with g (2)(0) < %, photon-indistinguishability >80 % measured single-photon efficiency 53 high numerical aperture fiber, 1.2 Megaclicks per second detectors under 80 MHz excitation clock-rates. Furthermore, show that indistinguishability prevail Our results Purcell-enhanced hCBG cavities prime candidate applications science.
