Fiber-based highly efficient entangled photon sources are an essential ingredient for quantum photonic networks. While the realization of fiber-coupled single photon sources has been attempted by various methods, direct fiber coupling of quantum dot based entangled photon sources has not been reported. In our work, we employ quantum dot nanomembranes directly attached to single mode fiber end-faces for efficient photon extraction. A key ingredient of efficient photon collection into fibers is the careful design and implementation of an air gap between fiber end face and quantum dot nanomembrane.
