  This thesis is devoted to the study of the coupling of single-photon emitters
with photonic nanostructures by using the properties of the near field of a
photonic structure in view of the realization of a compact integrated
single-photon source for quantum applications.
  The first part of my thesis work was consecrated to the optimization of
perovskites nanocrystals. Although perovskites nanocrystals are very promising
single-photon sources, they still need improvements: in this work, I review the
main properties of these emitters and present a full characterization of
perovskite nanocrystals with improved photo-stability, reduced blinking ad
strong antibunching.
  In the second part of the thesis, I focus on the coupling of quantum emitters
with various photonic structures: namely the tapered optical nanofibers and the
ion-exchange waveguides.
  The fabrication method and the optical properties of the nanofibers are
described in detail and the coupling of a single perovskite nanocrystal with a
nanofiber is achieved, which constitutes a proof of principle of a hybrid
integrated single-photon source.
  Finally, I show how the near field around ion exchange waveguides can be
employed together with near-field polymerization to trap single-photon emitters
onto the waveguides.
