This thesis is devoted to the study of the coupling of single-photon emitterswith photonic nanostructures by using the properties of the near field of aphotonic structure in view of the realization of a compact integratedsingle-photon source for quantum applications.  The first part of my thesis work was consecrated to the optimization ofperovskites nanocrystals. Although perovskites nanocrystals are very promisingsingle-photon sources, they still need improvements: in this work, I review themain properties of these emitters and present a full characterization ofperovskite nanocrystals with improved photo-stability, reduced blinking adstrong antibunching.  In the second part of the thesis, I focus on the coupling of quantum emitterswith various photonic structures: namely the tapered optical nanofibers and theion-exchange waveguides.  The fabrication method and the optical properties of the nanofibers aredescribed in detail and the coupling of a single perovskite nanocrystal with ananofiber is achieved, which constitutes a proof of principle of a hybridintegrated single-photon source.  Finally, I show how the near field around ion exchange waveguides can beemployed together with near-field polymerization to trap single-photon emittersonto the waveguides.
